1. This version does not have BMS, please use a lithium-ion battery with battery protection function
2. Please be sure to connect the antenna before transmitting, otherwise it is easy to damage the RF module
3. The T3-S3 V1.2 and T3-S3 V1.3 use the same pins; the only difference is the charging circuit.

* You can use GPIO10,21 by removing the two resistors in the figure below. Otherwise, the GPIO is connected to DIO8,DIO7 of Radio by default.
* SDA(18) and SCL(17) are not brought out and cannot be accessed. They can only be used as other GPIOs through QWIIC or header pins. During initialization, use explicit initialization `Wire.begin(sda,scl);` Any unused GPIO can be used as SDA and SCL.
