Parameter Description
Power consumption 3.3V/100 mA. Transient (5 us) current: 450 mA. Recommended supply current is ≥ 300 mA.
C1/C2 Power filter capacitor. They should be arranged near the 3.3V power supply pin.
TXD0/RXD0 serial port The user’s serial port for sending and receiving data.
Default baud: 9600, Data bit: 8 bits, Stop bit: 1 bit. No check bit, no flow control.
Note: If you need to use this serial port as a general I/O port, contact technicians.
TOUT pin The ADC pin cannot be used as a general I/O port.
Note: When not in use, the pin can float.
RST pin The module reset pin, which is active low. A pull-up resistor is included internally, and the pin can float.
LED2 pin Relay status indicator. When the I/O port outputs a low level, the indicator flashes.
LED1 pin Wi-Fi status indicator. When the I/O port outputs a low level, the indicator flashes.
Reset button Active low.
  • Press the button: Turn on or off the relay.
  • Press and hold for 5 seconds: Clear Wi-Fi configurations.
RELAY pin Coil for control of the relay. The maximum driving capacity of the module I/O port is 12 mA.
Note: The I/O driving capacity of the module shall be greater than the driving current required by the relay.
Other unused pins They can float.

Module antenna

The in-line mode is used by the module by default. In order to optimize the Wi-Fi performance, it is recommended to keep the antenna at least 15 mm from other metal parts.
