Beetle CM-32U4 Arduino Leonardo ATmega32U4

This is a compact Arduino Leonardo Board by DFRobot with a Lipo charging port.  The Beetle CM-32U4 has the most commonly used interfaces I2C, UART, SPI, and analogue + digital IO pins. With dimensions of just 22 x 20.5mm, the Beetle CM-32U4 is particularly suitable for applications where a very compact size is needed. The Beetle CM-32U4 supports a lithium battery, which can be connected directly via the pins on the board. In total, you can power the board in 3 ways. Via the USB-C port, Lipo battery via the BAT pin or with a 5V power source via the VIN pin.  

The Beetle CM-32U4 supports the official Arduino Leonardo firmware. This means that you can program it directly with Arduino IDE, without the need for extra downloads.
