Hi,
I need to move about 10 relays off a Raspberry Pi for my home automation project. I can find easily ready made, inexpensive boards that will connect to anything at 5V, like an Arduino. But there doesn't seem to be much on offer for the Pi's 3V3 GPIO. My current best find is Adafruit's 3-to-5 and any 5V relay board off DX or so.
I am looking for a ready made board or ready to build kit, as compact as possible. Ideally powered off the 5V pin available on the Pi, but I can live with another P/S.
Any recommendations?
