Allows RPI pin to control the buck converter enable pin, allowing the Pi to shut down the converter.

Duplicates RPI pins so that you can more easily attach multiple wires to pins.

Team 4272 designed Simple Power Breakout. CAD and BOM can be found on our Github page

Team 4272 Design MXP Port Breakout for the NI RoboRIO. Board is designed to allow us use MolexSL connectors for our digital and analog inputs. LEDs are also added as a quick visual for digital inputs. BOM and KICad files can be found on our Github.

This is a SparkMAX Breakout designed by FRC4272. This is designed to attach to our 3D printed mount. Schematic and BOMs can be found on our Github page. 3D printed mount can be found on our Printables page.

This is a USB type C jack that I specifically designed for Gameboy Pocket to wire to a lipo charging module. You need to solder it directly to the motherboard and replacing the DC jack connector, allowing you to have a better look on your build and get more room on the battery compartment. Can be charged with any USB-C charger safely, the jack board has a circuit on it that only provides 5v max input.

Instructions: USB-C BOARD. 1.- Solder 5.1k ohm resistors 0603 size to R1 and R2. 2.- Place and solder a USB-C 6 pin female jack to the board, you can bend the front anker pins so they can fit on the board or trim those ones. The USB-C port that you need should look like this one: https://aliexpress.com/item/4001054493231.html?spm=a2g0o.productlist.0.0.61233a56aRLM7o&algo_pvid=11ce47ef-8b4e-459f-82dd-ff9aaf936088&aem_p4p_detail=202111082245423538519152746340044004769&algo_exp_id=11ce47ef-8b4e-459f-82dd-ff9aaf936088-7&pdp_ext_f=%7B%22sku_id%22%3A%2210000013821822616%22%7D

GAMEBOY POCKET MOTHERBOARD. 1.- Remove the DC input connector from the motherboard. 2.- Clean the pads. 3.- Place the USB-C JACK BOARD to the Gameboy motherboard and solder the pads on the bottom of the board correctly. If you don’t solder the bottom pads to the Gameboy mother board the Gameboy WONT WORK. 4.- Solder the pads on the top of the board to the corresponding Positive (+) and negative (-) pads of your lipo charging module. 5.- Enjoy.

Order it with 0.8mm thickness.

OPTIONAL. You can also add wireless charging module to all the circuit, you just need to solder the positive and negative wires to the ones on top of the USB-C JACK board that are marked as “W+” and “W-“. You can order it with 1.6mm thickness or 0.8mm.

A simple video amplifier for composite video in a Famicom. Should also work fine in an NES Top Loader, but I haven’t tried it personally. Also includes a passthrough for audio, with a filter cap.

The solder points marked 20, 21, and 22 refer to pins on the PPU, and are ground, video, and 5 volts respectively. Audio can be taken from pin 46 on the cartridge connector.

50% duty oscillator. Complementary Outputs. uses mmbt7002dw

Mussel Gape Tracker Revision F. This version allows the use of two different versions of the DS3231 real time clock, either a 16-SOIC or 8-SOIC footprint. This version is still software compatible with earlier revisions.

Single board for mounting Allegro A1395, A1393, A1391 Hall effect sensors. Requires one 10k ohm resistor (0603 size) and one 0.1 uF capacitor (0603 size). ‘SLP’ is the sleep line, ‘VOUT’ is the output signal.
