Roller485-Lite power supply
-
Hi all! My first post here...
I'm planning to use a Roller485 to implement some simple machine control. I'll be using a M5Stack Core2 or similar to drive it via the I2C port, but I think that I will probably need the power levels of the PWR485 port.
Looking at the schematic, it looks like there is a blocking diode that will permit power to be supplied through the PWR485 port, but control to be provided through the I2C port - is this correct?
Many thanks in advance!

If you use a Roller485, you can connect directly to PortA of the Core2 to provide power + I2C control at the same time.Yes, you can use the 485 bus to provide power and I2C control at the same time.

@kuriko Excellent - many thanks!

@kuriko A follow-up question, if I may...
Can an M5Stack controller accept power from the Grove connector? If I connect an Atom-Lite to a Roller485Lite via the I2C port and supply 12V to the Roller485 through the PWR485 port, will this provide power to the Atom-Lite? There appears to be a path through the schematics...
TIA
Martin
