PSF-B04 module - 4-channel WiFi module integrated with the Sonoff eWeLink cloud
The PSF-B04 module is an advanced 4-channel WiFi module that works with the Sonoff eWeLink application to enable remote control of devices via WiFi. Equipped with the ESP8285 microcontroller, the module offers four voltage outputs (3.3V high state when the relay is activated in the application) and four inputs for control.
Main features:
- Compatibility with the eWeLink application: The module is controlled via the popular eWeLink app, allowing easy addition and configuration of devices in the home IoT network.
- Versatile power supply: The module is powered by 5V DC, compatible with USB power supplies such as phone chargers, powerbanks or computers.
- LED indicator: There is an LED on the board that indicates the status of the WiFi network connection, working in the same way as other Sonoff devices.
- Control inputs: Controllable via an external button or by shorting the corresponding pin to ground.
- High-level outputs: Four output signals, recommended for use with relay modules, activated by a high state.
The PSF-B04 module is ideal for home automation enthusiasts who are looking for a reliable and easy-to-configure solution for managing a variety of devices in the smart home. Its small size and low-current capability make it an excellent choice for projects requiring non-intrusive control.
Pinout description of the PSF-B04 module
- 3V3, GND,TX,RX,IO2 - connector for uploading your own software to the module e.g. Supla, Tasmot etc.
- +5V, GND - power supply pins 5V DC, module is not protected against reverse power supply
- Out1..4 - outputs of the module, when switched on, a high state appears on these pins: 3.3V
- KEY1..4 - inputs, short-circuiting of two pins results in switching on the appropriate output of the module or giving a low state
