Product Review

INTRODUCTION
Because the ATmega32U4 is sole microcontroller, Romeo V2 is simple and easy to use. The 32U4 chipset handles the USB directly, code libraries are available which allow the board to emulate a computer keyboard, mouse, and more using the very interesting USB-HID protocol! The best advantage is that ATmega32u4 has two serial ports which allows uploading sketches without removing wireless modules. Debugging is no longer a painful task.
