Adafruit – USB/DC Lithium Polymer battery charger 5-12V – 3.7/4.2v cells
Adafruit: 280
Description
Charge your single-cell lithium ion/polymer battery any which way you like with this board. Have a USB connection? No problem, just plug into the miniUSB connector. Only have a wall adapter? Any standard 2.1mm DC adapter which puts out 5 to 12VDC will work fine. If both are plugged in, the charger will automatically choose whichever has the highest voltage.
Other nice things about this charger include multiple LEDs for power & charging status, including a charging LED which will blink when the battery is full. If the charger gets too hot from high-speed charging, it will slow down the charge rate automatically. You can easily adjust the charge rate up to 1.2A or down to 100mA.
For use with Adafruit Lipoly/LiIon batteries only! Other batteries may have different voltage, chemistry, polarity or pinout.
- Use USB or DC power – 5 to 12V input
- Charges one single-cell 3.7/4.2v batteries (not for older 3.6/4.1v cells) with constant current/constant voltage
- Three indicator LEDs – green for Power, orange for charging and red for error
- Charging LED will blink when the battery is full
- You don’t have to worry about heat dissipation in the charger, even when plugging in a 12V DC power jack – thermal protection inside will slow down the charge rate to prevent damage
- 2 JST connections so you can keep the battery plugged in and powering your project
Terminal block connections galore (if you don’t like JST connectors) just solder in 3.5mm terminal blocks - Default charge rate is about 500mA, but you can easily change this by soldering in a through-hole resistor on. The chip can do 100-1200 mA charging
- Safety timer will stop charging after about 14 hours
- The chip supports a standard 10K thermistor, which we have stuffed as a standard resistor. You can solder in a thermistor easily
- Lots of information in the datasheet for the MCP73861
- Fully assembled, tested and comes with a free JST cable

Adafruit – Colorful Round Tactile Button Switch Assortment
Adafruit: 1009
Description
Little clicky switches are standard input “buttons” on electronic projects. These work best in a PCB but can be used on a solderless breadboard as shown in this tutorial. The pins are normally open (disconnected) and when the button is pressed they are momentarily closed.
These buttons are bigger than the 6mm ones we carry, and come in a pack of 15. Each button comes with a candy-colored round cap that snaps on. You get three of each color– blue, grey, yellow, green, and red. The round plastic button tops affix easily to the tactile switch body.
Assembled button dimensions: 12mm x 12mm x 12mm

Adafruit – PowerBoost 500 Shield – Rechargeable 5V Power Shield
Adafruit: 2078
Description
What’s a project if it’s trapped on your desk? Now you can take your Arduino anywhere you wish with the PowerBoost shield! This stackable shield goes onto your Arduino and provides a slim rechargeable power pack, with a built in battery charger as well as DC/DC booster.
Compatible with Arduino Uno, Duemilanove, Mega, Leonardo and Due – basically any Arduino-pinout-shaped Arduino as only the GND and 5V pins are used. You can stack shields on top, or stack the PowerBoost on top. Please note that the powerboost does not pass through the ICSP headers (the battery is in the way) so if your stacking shield uses ICSP for data transfer (like the Ethernet Shield), you’ll need to stack the PowerBoost above it!
The PowerBoost shield can run off of any Lithium Ion or Lithium Polymer battery (3.7/4.2V kind) but we suggest our 1200mAh capacity or 2000mAh capacity batteries, both of which fits very nicely in the empty space of the shield. Plug in the battery and recharge it via the microUSB jack. When you’re ready to go, just unplug the Arduino from USB or the wall adapter and it will automatically switch over to shield power.
The onboard boost converter can provide at least 500mA current, and can peak at 1A. There’s an onboard fuse to protect against higher current draws which could damage the boost converter or battery.
The shield comes as a kit of parts, some light soldering is required to attach the stacking headers and switch! Battery is not included, but you can pick one up in the shop (again, we suggest our 1200mAh battery or 2000mAh battery, but you can use any 500mAh+ size you like) There’s even an optional switch. If you choose to solder it in, it will let you turn the shield and Arduino power on/off.

Adafruit – FLORA – Arduino-compatible V1.0a
Adafruit: 659
Description
FLORA is Adafruit’s fully-featured wearable electronics platform. It’s a round, sewable, Arduino-compatible microcontroller designed to empower amazing wearables projects.
The FLORA is small (1.75″ diameter, weighing 4.4 grams). The FLORA family also has the best stainless steel threads, sensors, GPS modules and chainable LED NeoPixels, perfect accessories for the FLORA main board.
The FLORA has built-in USB support. Built in USB means you plug it in to program it, it just shows up – all you need is a Micro-B USB cable, no additional purchases are needed! We have a modified version of the Arduino IDE so Mac & Windows users can get started fast – or with the new 1.6.4+ Arduino IDE, it takes only a few seconds to add Flora-support. The FLORA has USB HID support, so it can act like a mouse or keyboard to attach directly to computers.

The FLORA has USB HID support, so it can act like a mouse or keyboard to attach directly to computers.
FLORA has onboard power switch connected to 2A power FET for safe and efficient battery on/off control, so you can power quite a bit without burning out your switch. The FLORA has an onboard 3.3v 250mA regulator with a protection diode and USB fuse so that the microcontroller voltage is consistent and can power common 3.3v modules and sensors.
We spent a lot of time on the power supply because the FLORA power system is specifically designed to allow easy control and power of a large quantity of addressable NeoPixels. Flora can easily drive 50 pixels directly from the onboard power supply, or up to 500 with the pixels externally powered by a separate 5V supply.
- FLORA is fabric friendly– all the components on board are flush to the PCB and won’t snag delicate garments (it does not use FTDI headers).
- FLORA is extremely beginner-friendly – it is difficult to destroy the FLORA by connecting a battery backwards due to polarized connector and protection diodes. The on-board regulator means that even connecting a 9V battery will not result in damage or tears.
- The FLORA has 4 indicator LEDs: power good, digital signal LED for bootloader feedback, data rx/tx. Also onboard is an ICSP connector for easy reprograming for advanced users. Flora v2 even has an RGB NeoPixel for even more colorful lighting.
- There are 14 sewing tap pads for attachment and electrical connections. Data buses are interleaved with power and ground pads for easy module and sensor attachments without worrying about overlapping traces which are not possible with conductive thread.
- The FLORA works great with the Arduino IDE and is super easy to install support if you have IDE 1.6.4 or later
The FLORA is not the first wearable Arduino / Arduino-compatible. Leah Buechley’s Lilypad was developed in 2007 and while they are both round, FLORA is a completely new platform that works seamlessly with the FLORA accessories.
The FLORA is made in NYC at Adafruit, it was designed by Limor Fried (Ladyada), Adafruit’s founder and engineer. Adafruit has a proven track record of providing 100+ high-quality libraries for Arduino/Arduino IDE, hundreds of tutorials, open-source code and contributions to the Arduino project. Ladyada was a member of the MIT wearables group and likes to sew.
You may get an off-white or black JST connector.

Adafruit – Micro Lipo – USB LiIon/LiPoly Charger
Adafruit: 1304
Description
Oh so adorable, this is the tiniest little lipo charger, so handy you can keep it any project box! Its also easy to use. Simply plug in the gold plated contacts into any USB port and a 3.7V/4.2V lithium polymer or lithium ion rechargeable battery into the JST plug on the other end. There are two LEDs – one red and one green. While charging, the red LED is lit. When the battery is fully charged and ready for use, the green LED turns on. Seriously, it could not get more easy.
Charging is performed in three stages: first a preconditioning charge, then a constant-current fast charge and finally a constant-voltage trickle charge to keep the battery topped-up. The charge current is 100mA by default, so it will work with any size battery and USB port. If you want you can easily change it over to 500mA mode by soldering closed the jumper on the back, for when you’ll only be charging batteries with 500mAh size or larger.
For use with Adafruit LiPoly/LiIon batteries only! Other batteries may have different voltage, chemistry, polarity or pinout.
- Comes assembled and tested with a free bonus JST cable!
- 5V input via PCB-style USB connector
- For charging single Lithium Ion/Lithium Polymer 3.7/4.2v batteries (not for older 3.6/4.1v cells)
- 100mA charge current, adjustable to 500mA by soldering a jumper closed
- Free 2-pin JST cable included!

SparkFun – Bluetooth Mate Silver
SparkFun: WRL-10393
Description: The Bluetooth Mate is very similar to our BlueSMiRF modem, but it is designed specifically to be used with our Arduino Pros and LilyPad Arduinos. These modems work as a serial (RX/TX) pipe, and are a great wireless replacement for serial cables. Any serial stream from 2400 to 115200bps can be passed seamlessly from your computer to your target.
Bluetooth Mate has the same pin out as the FTDI Basic, and is meant to plug directly into an Arduino Pro, Pro Mini, or LilyPad Mainboard. Because we’ve arranged the pins to do this, you cannot directly plug the Bluetooth Mate to an FTDI Basic board (you’ll have to swap TX and RX).
The RN-42 is perfect for short range, battery powered applications. The RN-42 uses only 26uA in sleep mode while still being discoverable and connectable. Multiple user configurable power modes allow the user to dial in the lowest power profile for a given application. If you need longer range, check out the Bluetooth Mate Gold.
The Bluetooth Mate has on-board voltage regulators, so it can be powered from any 3.3 to 6VDC power supply. We’ve got level shifting all set up so the RX and TX pins on the remote unit are 3-6VDC tolerant. Do not attach this device directly to a serial port. You will need an RS232 to TTL converter circuit if you need to attach this to a computer.
Unit comes without a connector; if you want to connect it to an Arduino Pro, we’d suggest the 6-pin right-angle female header.
Note: The hardware reset pin of the RN-42 module is broken out on the bottom side of the board. This pin is mislabeled as ‘PIO6’, it is actually PIO4. Should you need to reset the Mate, pull this pin high upon power-up, and then toggle it 3 times.
Features:
- Designed to work directly with Arduino Pro’s and LilyPad main boards
- FCC Approved Class 2 Bluetooth® Radio Modem!
- Low power consumption: 25mA avg
- Hardy frequency hopping scheme – operates in harsh RF environments like WiFi, 802.11g, and Zigbee
- Encrypted connection
- Frequency: 2.4~2.524 GHz
- Operating Voltage: 3.3V-6V
- Serial communications: 2400-115200bps
- Operating Temperature: -40 ~ +70C
- Built-in antenna
Dimensions:
- Board: 1.75×0.65″

Pololu – Adjustable Boost Regulator 2.5-9.5V
Pololu: 791
This powerful, adjustable boost regulator can generate an output voltage as high as 9.5 V from an input voltage as low as 1.5 V, all in a compact, 0.42? x 0.88? x 0.23? package. A trimmer potentiometer lets you set the boost regulator’s output voltage to a value between 2.5 and 9.5 V.
Overview
The Pololu adjustable boost regulator is a very flexible switching regulator (also called a switched-mode power supply, SMPS, or DC-to-DC converter) that can generate voltages higher than its input voltage. We offer two adjustable ranges: approximately 2.5 V to 9.5 V and 4 V to 25 V. The output voltage can be set using the trimmer potentiometer in the upper-right corner of the board. The input voltage range is 1.5 V to 16 V (the input voltage should be kept below the output voltage). The integrated 2 A switch allows for output currents high enough to drive small motors, as in our 3pi robot, and allows large voltage gains, such as obtaining 24 V from two NiMH or NiCd cells.
Some example applications include:
- Powering 5 V or 3.3 V systems from lower-voltage batteries
- Powering 5 V subsystems (e.g. sensors) in lower-voltage (e.g. 3.3 V) systems
- Achieving consistent actuator operation when powered by fluctuating batteries
- Powering high-brightness LEDs or a large number of LEDs in series
Note: For high-volume applications, this product can be customized with fixed output voltages ranging from 2 V to 30 V.
Feature Summary
- Input voltage: 1.5 V to 16 V
- Output adjustable from 2.5 V to 9.5 V or 4 V to 25 V
- 750 kHz switching frequency
- 2 A switch (and input) limit
- Integrated over-temperature and over-current shutoff
- Typical efficiency of 80-90% when doubling voltage and with 100-500 mA output
- Small size: 10.7 x 22.4 x 5.8 mm (0.42″ x 0.88″ x 0.23″)
- Weight without header pins: 1.6 g (0.06 oz)
