2.Hardware Design
2.1. Typical Connection
2.2. Power Interface
Working voltage VCC range from 1.9V~5.5V, 3.3V is recommended.Power the module by main power pin,
pin interface is in parallel with appropriate energy-storage capacitance and high frequency capacitance.
Circuit diagram as follows:

2.3. Reset, Reload and Wake up
nReload:nReload pin can connect to outer button . When press the button, pull down pin to low level, release
after 3s, module will restore factory defaults and restart.
nReset: Module reset pin, take affect when low level. There is 10K resistor pull up to 3.3V in module. When
module power on or break down, MCU will reset the module, pull down nReset pin as least 0.5s, then
release.
Wake_Up Key: Can connect to outer button or setup pin. When press the button to pull down pin to low
level,and release after 3s, module will wake up to normal work mode.
