I can't seem to get either the Quad Relay (https://www.sparkfun.com/products/16566) or the Single Relay (https://www.sparkfun.com/products/15093) to function using the Example sketches Example_2_Quad_Relay_Basics and Example_1_Single_Relay_Basics. I am using an Artemis Redboard Nano connected to the relay with a Qwiic connector. I power the quad relay with 10V from a lab power supply. Single relay doesn't need external power for the relay coils, as I understand it. Both power LEDs lights up, and the Serial print statements work, but no relay actuation (either audible, or measuring continuity with a multimeter).
I tested them one at a time, not daisy chained.
There is a CircuitPython library now available for the Qwiic Single Relay and the Raspberry Pi. The source code, examples, installation information and documentation are available on GitHub.
