GoPlus2 on Atom Lite

wrs642

haven't been able to operate the GoPlus2 module with the Atom Lite. Have grove connector from Atom pins 26,32 to PORTB1 of GoPlus2. GoPlus2 is powered by 12v and two 5g servos are connected.

I2C scan does not return a device.

setup includes:

M5.begin(true, true, false);
Wire.begin(26,32)

Anyone had success with this setup?

Hello @wrs642

Note:

port A (red) is by default I2C
port B (black) is by default IN/OUT
port C (blue) is by default UART

M5GoPlus2 has three port B, none of which is I2C. I2C is only available on MBUS (pins 21/22). Please check schematics here.

Thanks
Felix
