Keyestudio Arduino Leonardo R3+micro USB development board for DIY
Keyestudio Leonardo is a microcontroller board based on ATmega32u4 (datasheet). It is easy to use open source hardware. It contains everything needed to support the microcontroller. Simply connect it to your computer with a USB cable or power it with an AC-to-DC adapter or battery and you're ready to go. The ICSP (In-Circuit Serial Programming) header can not only program firmware into the Atmega32u4, but can also be used as an SPI communication interface. Keyestudio Leonardo can be powered via micro USB connection, or via external power jack (DC 7-12 V) or even via female Vin/GND headers (DC 7-12 V). Leonardo differs from other Arduino boards by using a separate USB-Serial chip in that the ATmega32u4 has built-in USB communication, eliminating the need for a secondary processor, allowing Leonardo to appear to the connected computer as a mouse and keyboard.
