Small converter PCB that changes the 2.54mm pitch 20 pin connector to a 10 pin ARM microcontroller style pinout with a 1.27mm pitch. For more information go to the project page

RFID Tag Antenna

• CAN
• OneWire
• RS485/DMX
• I2C
• Differential out for tiny ws281? remote (!!! NOT WORKING, as DMA would interfere with other channels)

Adds an XMC1400 to the Amiga which can be reprogrammed thru the Amiga serial port. This sits in the Paula socket and proxies the Amiga’s audio and serial outputs allowing software emulation of various sound chips and serial with much higher baud rates. Note that this does not REPLACE Paula.

Tester and breakout for FRC and similar digital I/O. The 3-pin 1x3 headers each carry Ground, +5v, and Signal, in that order. Build it as a tester, with male and female horizontal socket and header strips. Or omit the male headers, and directly solder in the wires from a limit switch or break-beam sensor. Designed by FRC team 4795.

Same as original except corrected logic level shifting circuit for SD card

Sonoff daughterboard

Full sized unregulated Poke Ball mod insert with dual DPAK N-Fets, Keystone 1098 dual 18350 battery tray, and a bunch of LEDs to light up your mod when fired, plus all of the prerequisite resistors and such!

Breakout Board for 2mm 3 Pin JST Connector to allow access to a 2S LiPo’s balancing leads and allow charging via a Hobby King DC-4S and custom charging cable!

Very simple limit switch breakout for DIY CD ROM 3D printer, plotter, etc. Connect 5v and ground to corresponding pads if you want the arduino pin to be pulled to ground when the switch isnt engaged, or reverse the polarity if you’d like it to be pulled high(the latter is the better option). the wires from each switch to the two switch pads, then the extra pad to the right of the switch pin to the arduino digital input pin you’re using for each switch. the fourth switch can be used to detect if filament has stopped extruding or run out and halt the process, or in my case as a second axis switch. of course if you want switches on either end of each axis you can use two boards and 6 digital pins
