GPIO13 and GPIO15. here is diagram

To use these GPIOs, do I need to call any library?
RE: KC868-A2 ESP32 I/O pin define - admin - 09-02-2025
ESP32 GPIO you can use it directly, without install library.

board KC868-A2-V2.5 - all the same?

just the GSM pin define should be:
tx_pin: GPIO5
rx_pin: GPIO13
