I've use A16 board I2C interface what is located in middle of board
for wiring I have used SDA, SCL and GND, no Vcc as A16 and relay board have different voltage 3v3 vs 5v
Basic PCF8576 IO extender board, and on top of that breakout board having 2x10p 2.54 female header. Only wiring what needed to that board is to transfer GND to another end of female pin header.
