Diagram 1 MCU(3.3V) & Module cooperative processing mode
Diagram 2 MCU(5V) & Module cooperative processing mode
1.The module is under the condition of 250Kbps rate and + 19dBm transmit power， power supply consumption: 3.3V, the typical current is about 120mA. Proposed supply current≥300mA. 2. Power filter capacitor C1 & C2 should be distributed as close to the 3.3V pin as possible.C1 & C2≥10uF. 3. RESET 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.
