Hi, I am trying to work out the resistor values for RG1 and RG2 for the Latch Driver Board v3.1 I am trying to assemble from scratch. I managed to find the values for all the other components, but only the package size seems to be listed for these and I’m not confident enough to work them out for myself would someone be able to help me out with this?
Those are current limiting resistors. You only need one (either RG1 or RG2), of 1 ohm value, SMD 2512 package. We only have 2.2 ohm in stock so we populated both to make an equivalent of 1 ohm. The current limiting resistor helps in situations of shorted solenoid etc.
