Diagram 1 MCU(3.3V) & Module cooperative processing mode
Diagram 2 MCU(5V) & Module cooperative processing mode
1.The power supply consumption: 3.3V,proposed supply current≥100mA. 2. Power filter capacitor C1 & C2 should be distributed as close to the 3.3V pin as possible.C1 & C2≥10uF. 3. RST pin is module hardware reset pin, effective under the low level. Without external circuitry, it can be directly connected to the IO port of MCU for use. 4. The SDA pin is the low power control pin, the MCU sends and the module receives. 5. The SCL pin is the connection status indicator pin, the module sends and the MCU receives.
