Required components


Note1: It is advised to use FTDI USB-serial converter, as serial FTDI chips are by default working well in Linux.
The Paparazzi ground station software is configured to look for modems on FTDI ports by default.
This harness can also serve as a modem interface (after it's use in Bootloader uploading) if you plug it on Umarim's UART1 connector
