“Perfect for what I wanted! I've used a pi zero and two 2x relay boards for one half of my project and later an esp32 with another two 2x relay for the second half. This all in one solution really neatens up my whole setup and I can run it with a lower power pi pico now on wifi which is a superb combination!”
“The board is very well made and got it working quickly which is alway nice
I think a nice touch would be to have breakout headers at least on unused ports so additional stuff can be achieved on this board
Just an idea I have found another way for my project”
“Well made product. but documentation is sketchy and example code is for the brave: requires some careful reading and modification.
I wanted to control the relays over USB from another system (rPi 4) and it turns out that the C code on https://www.waveshare.com/pico-relay-b.htm lets you do that, writing from the host over the serial port. I can "echo -nr "\x04" > /dev/serialetcetcetcetc and lo and behold relay 4 switches on!”
“Great module that is very easy to use, provides a good enclosure for a Pi Pico and clips directly onto DIN rail. I couldn't but the respective parts for this price let along incorporate them into a finished article. V good”
