This is an 8-channel remote in a compact board suitable for remote ON/OFF applications using Bluetooth or Wi-Fi protocol. The board consists of an ESP32 module and 8 tactile switches connected to various GPIO. The circuit works with 3.3V_DC power supply and a Li-Ion battery can be used to power the board. The onboard LED indicates the power. There is an onboard programming connector that helps users program the ESP32 module using Arduino IDE. The users have to write their own code to use the module, according to their requirements.
