There is absolutely no end to the number of different types of modules and devices in which the ESP family of WiFi modules/microcontrollers have been featured, thanks to their integrated nature and small form factor. While the ESP8266 and ESP32 variants are the most known, other less-known versions like the ESP8285 have recently been garnering popularity with several products based on it, including the recently released PSF-B 4-gang Wi-Fi Switch Module, by china-based home automation solution provider; ITEAD.
A 1-4 gang ultra-low-power Wi-Fi switch module, the ESP8285-based PSF-B Switch module was designed to enable rapid development of WiFi-based, home automation switch solutions. It comes with the ability to switch up to four independent household points/appliances and can be controlled via connected pushbuttons, or controlled remotely by connecting it to a privately developed, or publicly available app like ITEAD’s eWeLink.
