2.1. Typical Connection 2.2. Power Interface USR-WIFI232-B2 adopt single-voltage 3.3 V power supply. Peak current is about 350mA, work current is about 200mA and sleep mode current is 100mA. The power filter is recommended to be used near the connector of the user board, and it is recommended to use two parallel decoupling capacitors with 100uF and 10uF to improve the stability of the system and wireless performance. -
