Attention:
1. The maximum instantaneous current consumption of ESP8285 can reach 400~500mA, so 500mA power supply is recommended. Ldos such as XC6206 and 7533 cannot be used.
2. The ESD capability of the ESP8285 is slightly weak. Pay attention to electrostatic protection in a dry environment.
3. Based on the 500mA power supply requirement, it is recommended that the line width of the PCB, including VCC and GND, is not less than 30mil. If the power cord has a through hole, it is recommended to use 2 to 3 through holes to prevent PCB production problems.
4. For better RF performance, refer to the module placement method in the manual. If the product has certification requirements, it is recommended that there be no parallel lines near the PCB antenna, and the download interface should be reserved far away from the antenna.
5. It is recommended to erase the module before downloading the program, otherwise it may cause some unpredictable problems.
6. If the module fails to start, restart the module. You are advised to check the power supply, including the power supply, the width of the power cable, the through hole on the power cable, and the power supply with the diode in series.
