@cepics The RST pin assignment for COMX LTE (SKU:M031-A) is not provided in the materials. However, since the module uses AT commands for control (via UART 115200bps), you may not need a dedicated RST pin connection if using software reset via AT commands (e.g., AT+CFUN=1,1 to reset the module).
For Adafruit_FONA compatibility, if a hardware RST is required, you can connect an unused GPIO pin from Core1 (e.g., G2) to the module's RST pin (refer to the module's schematic for exact RST pin location, typically labeled "RST" or "RESET" on the PCB).
