Foca

Overview

Foca V2.0 is a USB to serial UART board with XBee interface socket. It’s the essential tools for establishing communication between PC and mostly MCU or use XBee. Especially, it’s the optimum tool for the board which basic Arduino but without USB interface, like Sniffer Nano, Colorduino and etc.

Features
