The Beetle-ESP32 Microcontroller is only 35 x 34mm (1.38 x 1.34in.) in size and is a simplified version of FireBeetle-ESP32, specially designed for electronic engineering fans and DIY lovers. It is equipped with 4 analogue ports, 4 digital ports, UART and I2C interfaces, making it a perfect replacement for many physically larger boards.
The microcontroller enables users to directly burn programs via the on-board USB interface and has Bluetooth and WIFI integrated in the microcontroller for supporting more applications.
