- 15 - External MCU Wi-Fi module Capacitor Groundin g Fig 9 Circuit diagram (3.3V) If your device is powered by 5V, you can refer to the circuit shown in Fig 10 or design your own circuit for power conversion. The value of resistor can be adjusted according to actual circuit design.
- 16 - 5.2. Power Supply Requirement If an LDO is used to supply the module with 3.3V power, C1 capacitor can be considered to be used with 10uF-22uF; If a DCDC is used to supply 3.3V power, C1 capacitor can be considered to be used with 22uF. It is recommended to supply the module with power higher than 450mA to ensure enough power supply to the module and avoid power down during data. The module is designed with 2x 3.3V pins. You can power the module with either pin or both pins.
