The Beetle ESP32 is a compact microcontroller measuring 35mm x 34mm, based on the Tensilica LX6 dual-core processor (240MHz). It integrates 520KB of SRAM and 16Mbit of Flash memory. The board provides Wi-Fi (802.11 b/g/n) and Bluetooth 4.2 (BR/EDR/BLE) connectivity. It features large, gold-plated I/O pads for easy connection. The I/O includes 4 digital pins, 4 analog pins, one I2C interface, and one UART serial port. The board can be programmed directly via its Micro USB port and can be powered by 5V via USB or 3.5-6.5V via the VIN pin.

This microcontroller enables users to directly burn programs via the on-board USB interface. Meanwhile, Bluetooth and WIFI are integrated in the microcontroller for supporting more applications. With this Beetle-ESP32, you can easily build up your dreaming project.

Features :

• A small size of 35mm×34mm
• Enable users to directly download and debug programs through Micro USB, free from programmer.
• Large-scale I/O ports with gold plating, easy to screw wire on it or to sew the board on the clothes with wires, no need to solder.
• A group of gold plating power interfaces of honeycomb type, convenient to use.
• Integrate WIFI and Bluetooth
