GPS Receiver – GP-20U7 (56 Channel)
The GP-20U7 is a compact GPS receiver with a built-in high performances all-in-one GPS chipset. The GP-20U7 accurately provides position, velocity, and time readings as well possessing high sensitivity and tracking capabilities. Thanks to the low power consumption this receiver requires, the GP-20U7 is ideal for portable applications such as tablet PCs, smart phones, and other devices requiring positioning capability. With 56 channels in search mode and 22 channels “All-In-View” tracking, the GP-20U7 is quite the work horse for its size.

AltIMU-10 v5 Gyro, Accelerometer, Compass, and Altimeter
The Pololu AltIMU-10 v5 is an inertial measurement unit (IMU) and altimeter that features the same LSM6DS33 gyro and accelerometer and LIS3MDL magnetometer as the MinIMU-9 v5, and adds an LPS25H digital barometer. An I²C interface accesses ten independent pressure, rotation, acceleration, and magnetic measurements that can be used to calculate the sensor’s altitude and absolute orientation. The Pololu AltIMU-10 v5 is a compact board that combines ST’s LSM6DS33 3-axis gyroscope and 3-axis accelerometer, LIS3MDL 3-axis magnetometer, and LPS25H digital barometer to form an inertial measurement unit (IMU) and altimeter.

SparkFun Air Quality Breakout – CCS811
The CCS811 Air Quality Breakout is a digital gas sensor solution that senses a wide range of Total Volatile Organic Compounds (TVOCs), including equivalent carbon dioxide (eCO2) and metal oxide (MOX) levels. VOCs are often categorized as pollutants and or sensory irritants and can come from a variety of sources like construction materials, machines and even people. This breakout is intended for indoor air quality monitoring in personal devices such as watches and phone.

SparkFun Thing Plus – ESP32 WROOM
The SparkFun ESP32 Thing Plus is the next step to get started with Espressif IoT ideations while still enjoying all the amenities of the original ESP32 Thing. Espressif’s ESP32 WROOM is a powerful WiFi and Bluetooth MCU module that targets a wide variety of applications. At the core of this module is the ESP32-D0WDQ6 chip which is designed to be both scalable and adaptive. To make the Thing Plus even easier to use, we’ve moved a few pins around to make the board Feather compatible and it utilizes our handy Qwiic Connect System which means no soldering or shields are required to connect it to the rest of your system.
The ESP32 Thing plus integrates a rich set of peripherals, ranging from capacitive touch sensors, SD card interface, Ethernet, high-speed SPI, UART, I2S and I2C. Thanks to the onboard ESP32 WROOM module, the SparkFun Thing Plus features 16MB of flash memory, 520kB of internal SRAM, an integrated 802.11 BGN WiFi transceiver and dual-mode Bluetooth capabilities, and a JST connector to plug in a LiPo battery.

ACTION Commands
Begin by sending the inquiry scan command: I,
If the modem finds any modules, you can try sending the connect command: C,
< to connect to one of them. The modem in the example above found one devices in range, by sending the C,0006664FAE18 command, we can attempt to connect to one of them. After sending the connect command, the device will respond with "TRYING", which will be followed by either "CONNECT failed" or the connection will be successful. After a successful connection we immediately enter data mode, and the modem becomes a pipeline. Any characters sent from one Bluetooth device will be sent to the other, and vice-versa.

Moteino
Moteino began as a low power wireless Arduino compatible development platform based on the popular ATmega328p chip used in the Arduino UNO. Moteinos are compatible and can communicate with any other Arduino or development platform that uses the popular HopeRF RFM69 or LoRa transceivers, or even the older RFM12B. Moteino also comes with an optional SPI flash memory chip for wireless programming, or data logging. Moteino was designed to be a compact, highly customizable and affordable development platform, suitable for IoT, home automation and long range wireless projects.
Moteino in RFM12B to rebuild suggests doing as new without completely replacing. I decided to stripped down at RFM12B and rebuild in Bluetooth.

MPU-9150
MotionInterface is becoming a “Must-Have” function being adopted by smartphone and tablet manufacturers due to the enormous value it adds to the end user experience. In smartphones, it finds use in applications such as gesture commands for applications and phone control, enhanced gaming, augmented reality, panoramic photo capture and viewing, and pedestrian and vehicle navigation. With its ability to precisely and accurately track user motions, MotionTracking technology can convert handsets and tablets into powerful 3D intelligent devices that can be used in applications ranging from health and fitness monitoring to location-based services. Key requirements for MotionInterface enabled devices are small package size, low power consumption, high accuracy and repeatability, high shock tolerance, and application specific performance programmability, all at a low consumer price point.

SparkFun Bluetooth Mate Silver
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.
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. 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.

Microcontroller
A microcontroller is a small computer on a single Metal-Oxide-Semiconductor (MOS) integrated circuit (IC) chip. A microcontroller contains one or more CPUs (Processor Cores) along with memory and programmable input/output peripherals. Program memory in the form of ferroelectric RAM, NOR flash or OTP ROM is also often included on chip, as well as a small amount of RAM. Microcontrollers are designed for embedded applications, in contrast to the microprocessors used in personal computers or other general purpose applications consisting of various discrete chips.
A microcontroller is a “Simple Computer” that runs one program in a loop. They are designed to perform a single, specific task. In this guide, we’ll be focusing on microcontrollers that have breakout boards, or a board that makes it easier to connect to and program the microcontroller. On a breakout board, the microcontroller pins are soldered to a printed circuit board, headers or other connectors are added to the PCB, and some basic firmware, or permanent software, is loaded to prep the microcontroller to receive signals.
There are different microcontrollers and it can be daunting to get started, especially if you’re just getting into electronics.
- Arduino Uno, etc, (5V/16MHz, 3.3V/8MHz) is a microcontroller board based on the ATmega328.
- Arduino Micro, etc, (5V/16MHz, 3.3V/8MHz) is a microcontroller board based on the ATmega32U4.
- Arduino Mega 2560, etc, (5V/16MHz) is a microcontroller board based on the ATmega2560.
- Arduino Due, etc, (3.3V/84MHz) is a microcontroller board based on the AT91SAM3X8E.
- Arduino Zero, etc, (3.3V/48MHz) is a microcontroller board based on the ATSAMD21G18 ARM Cortex M0+.
- Arduino Nano 33, etc, (3.3V/120MHz) is a microcontroller board based on the ATSAMD51 Cortex M4.
- Espressif ESP32 WROOM, etc, (3.3V/240MHz) is a microcontroller board based on the Espressif Xtensa® dual-core 32-bit LX6.
- Raspberry Pi 4 Model B (5.1V/1.5GHz) is a microcontroller board based on the Broadcom BCM2711, quad-core Cortex-A72 (ARM v8) 64-bit SoC.
- Raspberry Pi Zero W (5.1V/1GHz) is a microcontroller board based on the Broadcom BCM2837B0 64-bit ARM Cortex-A53 Quad Core Processor SoC.
