Anyone know of a good relay board, that can be interfaced from a mcu using either 1digital output (20ma max, or if need be I can include the transistor) per relay, or simple serial comm at low baud rate.
Should run and trigger at 5VDC. Needs 4-8outputs each capable of 230Vac 5amp Preferably with a case included.
The board should include rectifiers, transistors, and other components to make it work from a 5VDC source with 20ma triggers, or a serial protocol.
I would prefer a EU store, but any ideas is welcome.
