UHF RFID Unit (JRD4035) on M5Core2

  • I was wondering if the examples from the M5Stack Repository will be re-released on the M5Core2 repository. Unfortunately I am not able to get my JRD4035 running on a M5Core2. Anybody maybe has experience in this or info when examples will be released?

    Best wishes

  • Hello @tobias-h

    you could try to modify the M5Stack example yourself.

    Replace below line:

    #include <M5Stack.h>


    #include <M5Core2.h>

    and below line:

    Serial2.begin(115200, SERIAL_8N1, 16, 17);//16.17

    with this line if you connect the unit to port A (found on M5Core2):

    Serial2.begin(115200, SERIAL_8N1, 33, 32);

    or this line if you connect the unit to port C (found on M5GO Battery Bottom2):

    Serial2.begin(115200, SERIAL_8N1, 13, 14);
