Driver Installation

Foca Pro adopts CP2102 chip instead of FT232RL chip on Foca board, thus we cannot use driver file in the driver directory of Arduino IDE to install the driver.

You can download CP2102 driver for different platforms including MAC version, Linux version and Windows version. Once downloaded, plug in Foca Pro, search for CP2102 among the unknown devices, then click Upgrade Driver and manually install. Point the driver position to the downloaded driver directory and then install, finally the corresponding serial number can be found on IDE.
