Need 32 channels of digital IO for Feather Huzzah

by awardblvr on Tue Oct 31, 2017 11:37 am

(or 16 will do for a proto)

What is the best BOARD that will make it easy to switch 32 (or 16) relays (via the common Opto-isolate interface).
So... basically digital output 0 - 3 or 0 - 5 volts. Source or sink. But a SMALL form factor and hopefully just one board to interface with Feather Huzzah or PyCom board.

So some I2C or SPI based GPIO device is fine.

Please advise.

A couple of these should do it: https://www.adafruit.com/product/732

Thats the problem... I do not want to wire these up myself. I want a board that mounts to the Feather Huzzah and has these already connected.

Sounds like a great Adafruit opportunity... (BTW.. this is for a company that may want to use these in a factory to control a bunch of relays)
