Note: the power supply section
1, modules working voltage Can choose DC 3.3V or DC 5V, such as purchase module, power supply voltage is DC3.3V power supply parts must add DC5V turn 3.3V DCtoDC circuit, refer to section module power supply!Power supply must adopt dc DCtoDC power IC (it is recommended to use power supply IC model QX3406AL/power IC G5728 / power IC LP3204AADB5F package SOT23-5) specific reference schematic diagram!
2, advice, do not use zener diode, triode, such as "1117-3.3 series voltage regulator IC, for example, because the WIFI at work current change along with the change of network traffic state, place of fluctuations, when it.Output voltage instability easily leads to unstable or WIFI module chip burn out.This phenomenon occurred in the client application, after using DCtoDC power supply has not found a similar phenomenon.Please pay attention!
3, DCtoDC output power inductor current can reach more than 300 ma, best recommended (SMD laminated power 0805 MCL2012S2R2MT along the winding inductance Sunlord), current (WIFI work in 95 ~ 95 ma) current is too small will lead to an unstable WIFI work and excessive heat and burn out chip.A similar phenomenon has encountered in the process of customer service.

Note: antenna part
1, this part need to do 50 r single line impedance;
2, layout Line: walk arc line or lines, try to get the line is short, had better not exceed 10 mm
3, regular posted 0 R resistor R1 position, C1 C2 don't stick (C1 C2 R1 for the antenna matching circuit, parameters
According to different antenna adjustment), please try to close to the WIFI module, this part its furthest distance can not exceed 10 mm.
