Drivers
Driver is any MCP23017 driver.
Arduino Driver
Uses Adafruit driver Adafruit_MCP23017 Example code at ODAS-RELAY-16 Example Code. Raspberry Pi Driver Uses Adafruit Raspberry Pi driver Driver Alternate library Wiring Pi
Raspberry Pi Pico
MMBASIC
- SWLEDX8-01.bas - Read 8x switches, write 8x LEDs

Parts List / Assembly Sheet
Changes in Rev X2 PWB
Narrower footprint for K1-K16 relay parts Changed relays to to 4x4 array Issues with Rev X1 PWB Pad spacing on relays is too wide Part is narrower than a normal 8 pin DIP
Rev X1 Layout
