Download Firmware:

Pull-down BOOT to LOW level, then you can download firmware in ESP Download Tools software.

Note:

The maximum instantaneous current consumption of ESPC2 can reach 400~500mA, so the recommended power supply is 500mA. LDOs such as XC6206 and 7533 cannot be used;

Based on 500mA power supply requirement, it is recommended that the PCB wire width including VCC and GND is not less than 30mil. If the power line has vias, it is recommended to use 2~3 vias to prevent PCB production problem;

For better RF performance, please refer to the module placement method in the manual. If the product has certification requirements, it is recommended that there is no parallel wires near the PCB antenna, and the download interface should be reserved far from the antenna;

It is recommended to erase the module before downloading the program, otherwise there may cause some unpredictableproblems;

If the module fails to start normally and keeps restarting, it is recommended to check the power supply, including power supply, power trace width, vias on the power trace, diodes concatenated power supply, etc.;
