OpenSprinkler Forums Hardware Questions Hardware Rev 2.3 Reply To: Hardware Rev 2.3



As I looked into the previous relay implementation, I see that it was driven from D6 with a npn driver, so I should try to replicate thay with a 5vdc relay rather than a 24vac relay.

It’s hard to tell for sure by looking at the board, but it doesn’t look like this pin is brought out to any through-hole contacts. Would I need to solder directly to the uC pin?

Ray, can you upload the latest schematics to github? Also, were there any FW changes for this HW rev? Or will it still control this pin if selecting activate relay for a station?
