Here’s my code that has been successfully working on a Mayfly v1.1 RevB board, with a Hydros21 connected to the D4-7 Grove jack (with jumper set to the switched 3v setting) and a Y-511a and our custom RS485 adapter connected to the D5-6 jack and an external (non-Mayfly) 12v source supplying power for the Y-511a.
