      When I use m5stack core2 with mbus as Input and 5v input, serial2 does not work and the microcontroller shuts down. m5stack core2 with mbus as Output and 5v input to BAT pin works fine.Is there a problem if I use 5V input to the BAT pin of m5stack core2?

        Hello @mu0104

        that doesn't sound right. I have an M5Core2 which is solely powered via the 5 V input from the stacked COM.X module and the communication between the two uses Serial2 (aka GPIO13 and GPIO14) successfully.

        Do you care to share your code?

        Thanks
