SparkFun – ProtoBoard – Wombat (PTH)
SparkFun: PRT-08619
Description: An empty canvas for electrical enthusiasts! Designed to fit the SFE project enclosures this project board gives you 8x10cm (3.15×3.94″) of building space for through-hole components with 2.54mm (100mil) spaced holes. This is not your normal perf board! This board is much higher quality with plated-through holes and annular rings that will not lift off the PCB under normal soldering conditions.
The marsupial naming convention is what happens when you let Engineers into a Marketing meeting. They looked so happy, we just couldn’t tell them no. Wombat is the board with nothing but PTH prototyping pads.
Dimensions: 8x10cm (3.15×3.94″)

Adafruit – Perma-Proto Quarter-sized Breadboard PCB
Adafruit: 1608
Description
Customers have asked us to carry basic perf-board, but we never liked the look of most basic perf: its always crummy quality, with pads that flake off and no labeling. Then we thought about how people actually prototype – usually starting with a solderless breadboard and then transferring the parts to a more permanent PCB. That’s when we realized what people would really like is a proto board that makes it easy!
This proto-board is the PCB you always wish you had, but never realized it! We took the basic layout of a quarter-sized breadboard (basically, a ‘tiny’ breadboard plus power rails) and turned that into a beautiful PCB. The top side has a white silkscreen, and the same markings you’re familiar with, to make transferring components easy. The bottom has the 5-hole pad design that matches a classic breadboard, with 4 power bus lines on the sides, and no mask so you can easily cut traces when necessary. We used 1.2mm diameter drill holes so even parts with big leads will fit. All holes are thru-plated for strength – these wont peel off with rework. The finish is a gold plate – you won’t get oxidation like with bare copper perf! There are also two mounting holes so you can attach the PCB to your project box.
Once you use a Perma-Proto board, you’ll never go back!

SparkFun – Spring Terminals – PCB Mount (6-Pin)
SparkFun: PRT-08077
Description: These are small spring terminals. Open the aperature with the small arm, insert the wire, release the arm and the wire is held firmly in place. This is a good quick way to to interface to bare wires. Capable of higher current and more resilient than breadboard or female header type connections.
Terminals with 0.1″ standard spacing. Inserts directly into perf and proto board. Comes in 2, 3, 4, 5, and 6 positions. Rated up to 150V @ 2A. Terminal can accept 26 to 20AWG wire.

SparkFun – Nut – Nylon Locknut (4-40)
SparkFun: PRT-10460
Description: These are standard locknuts with 4-40 thread. For use with 4-40 machine screws. They have a nylon insert that allows them to stay tightly in place.
Note: These come in packs of 10.

Steward-MacDonald – Orange Drop Caps
Steward-MacDonald: 1281
Upgrade to the quality caps used in Fender and Gibson guitars.
Made of durable high grade polyester, and favorites for vintage restorations or new builds.
Capacitors are energy-storage devices that filter the high frequencies. A cap lets the tone control roll off the treble response, progressively warming the tone. The higher the value, the more bass output from the tone control at its “zero” setting.
A cap wired to a potentiometer creates a standard tone control, as explained in this Article: How a tone control works.
100V. Sold individually.
- .022uF 223K Humbucker Tone

Adafruit – Lithium Ion Battery – 3.7v 2000mAh
Adafruit: 2011
Description
Lithium ion polymer (also known as ‘lipo’ or ‘lipoly’) batteries are thin, light and powerful. The output ranges from 4.2V when completely charged to 3.7V. This battery has a capacity of 2000mAh. If you need a larger (or smaller!) battery, we have a full range of LiPoly batteries
The batteries come pre-attached with a genuine 2-pin JST-PH connector as shown and include the necessary protection circuitry. Because they have a genuine JST connector, not a knock-off, the cable wont snag or get stuck in a matching JST jack, they click in and out smoothly.
The included protection circuitry keeps the battery voltage from going too high (over-charging) or low (over-use) which means that the battery will cut-out when completely dead at 3.0V. It will also protect against output shorts. However, even with this protection it is very important that you only use a LiIon/LiPoly constant-voltage/constant-current charger to recharge them and at a rate of 2A or less (500mA is best). We suggest our Micro Lipo charger, which has a 100mA default rate. You can also set the Micro Lipo to 500mA rate for a faster charge.
Like most lipos, the batteries we sell do not have thermistors built in. This is why we suggest charging at 1 C or even less – 100 to 500mA is a good rate, and available from any USB port if using a USB-powered charger.
Additional safety notes: Do not use a NiMH/NiCad/lead-acid charger! Also, do not abuse these batteries, do not short, bend, crush or puncture. As with all Lithium ion polymer batteries and with any power source – they should be used by experts who are comfortable working with power supplies.
Technical Details
- Dimensions: 60mm x 36mm x 7mm / 2.4″ x 1.4″ x 0.3″
- Weight: 34g
- Nominal Capacity: 2000mAh ±2%
- Nominal Voltage: 3.7V

SparkFun – Polymer Lithium Ion Battery – 1000mAh
SparkFun: PRT-00339
Description: These are very slim, extremely light weight batteries based on the new Polymer Lithium Ion chemistry. This is the highest energy density currently in production. Each cell outputs a nominal 3.7V at 1000mAh! Comes terminated with a standard 2-pin JST-PH connector – 2mm spacing between pins. These batteries require special charging. Do not attempt to charge these with anything but a specialized Lithium Polymer charger.
Battery includes built-in protection against over voltage, over current, and minimum voltage. Please use caution when using this battery in wearable projects. When using conductive thread, a short in the thread can create sparks and heat. We recommend using coin cell batteries for beginners.
Note: Although these cells are rated for 2C continuous discharge, the wiring and connectors are only rated up to 1A, so be sure to take that into account when determining your power requirements.
Note: Be careful with the JST connectors. They can stick in pretty good and tugging on them can damage the connector.
Dimensions: 50.8 x 33.5 x 5.9 mm
Weight: 22g
Features:
- Excellent long-term self-discharge rates (<8% per month)
- Robust power source under extreme conditions (-25 to 60C)
