Feature

●2. Based on power supply requirement 500mA, is recommended that power and ground traces be no less than 30mil. If there are vias in power is recommended to make 2~3 holes toPCB production deviation.
●1. maximum RF instantaneous current ESP8285 can reach 400~500mA, so minimum power supply requirement is 500mA. LDOs such as XC6206 and 7533 cannot be used static ability ESP8285 is slightly weaker. In dry season in winter, pay attention to electrostatic protection.
●3. For better RF performance, please refer to module placement method in manual. If product has certification requirements, is recommended that there should be no parallel wiring near PCB antenna, and download interface should reserve a pad away from antenna.
●5. If module fails to start normally and keeps restarting, is recommended to check power supply including parameters power supply material, width power supply vias on power supply diodes connected in series on power supply, etc.
●module chip is ESP8285, its built-in storage is 16Mbit, and has various certifications such as FCC/CE/SRRC.


Description

Precautions
1. maximum RF instantaneous current ESP8285 can reach 400~500mA, so minimum power supply requirement is 500mA. LDOs such as XC6206 and 7533 cannot be used;
2. static ability ESP8285 is slightly weaker. In dry season in winter, pay attention to electrostatic protection;
3. Based on power supply requirement 500mA, is recommended that power and ground traces be no less than 30mil. If there are vias in power is recommended to make 2~3 holes to PCB production deviation;
4. For better RF performance, please refer to module placement method in manual. If product has certification requirements, is recommended that there should be no parallel wiring near PCB antenna, and download interface should reserve a pad away from antenna;
5. Before downloading program, is recommended to wipe module clean, otherwise there may be some failures to start;
6. If module fails to start normally and keeps restarting, is recommended to check power supply including parameters power supply material, width power supply vias on power supply diodes connected in series on power supply, etc.
