A comment on Pine64 Ox64 $6 RISC-V Linux hybrid SBC.

Does anyone know if this would be able to control a pair of relays on a network? I'm looking to control two electric heaters in my garage. I'd also like a pair of temp sensors. The hardest part of the project so far is the voltage to run a 240v relay is higher than the boards I've looked at can put out.

Any advice, or places I can go to for advice on projects like these would be appreciated.

Voltage or current? Either way, chaining relays (or maybe a transistor) would be the answer. I.e. use a 10mA output to run a transistor, providing the 250mA that the relay needs. Use a parametric search (like digikey, mouser) to find a relay with a low voltage coil and high voltage/current contacts.

It's probably both, I haven't checked the current requirements yet. I was originally planning to use a raspberry pi zero. the GPIO pins put out 5 or 9v, but the relays that handle 240v run on...I think it was 12v.

What about Solid State Relays? I think one of mine takes 5v-30v input and I switch mains with it.

awesome, I'll look into it. Thanks!
