A: Looking at the schematic diagram of the ESP lyra mini T board you mentioned, it has occupied the pins as much as possible, and no extra IO has been found. If some functions can be discarded, I2C functions can be realized, such as turning off the TF card, using gpio13 and gpio15 to connect to the i2c device, and the development board has a reserved pad.
