Beetle ESP32 Microcontroller

This Beetle ESP32 Microcontroller is just 35x34mm in size, and is a simplified version of DFRobot's FireBeetle-ESP32. It is equipped with 4 analog ports, 4 digital ports, UART and I2C interfaces.

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 new project.

Features

• Just 35mm×34mm in size
• Enable users to directly download and debug programs through Micro USB, free from programmer.
• Large 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
