This is a VIK module designed to allow you to experiment and prototype.
It includes:
- MCP23017 I/O expander
- 74hc595 shift register
- WS2812B 5050 leds
- MX/Choc V1/Gateron low profile switch footprint, both hotswap and solderable
- Row/Column and Direct Pin switch configuration (default is Row/Column)
- EC11 footprint
All pins are broken out. If you have female headers connected, you can experiment with your wiring, write firmware, and prototype / test features.
Big thank you to GeorgeN for the suggestion for this module
Thanks to petejohanson for providing additional tips along the way
For PCB fabrication, you can use the files in the production folder.
- gerbers.zip - the file used to fabricate the pcb
- bom.csv - used for PCBA. You can also use the part numbers in this file to look up the exact parts as lcsc.com
- positions.csv - used for PCBA
Using the 3 files above, this has been tested at jlcpcb.com
