MarsBoard/Uart

Connection
The marsboard P2 connector includes the UART 0 signals as 3.3V TTL! .

You will need a TTL to RS232 line converter, or use a suitable TTL USB-serial adapter (such as the FTDI-232R-3V3-WE - USB to TTL Serial Cable). The MarsBoard P2 header is a 2x35 2mm header if you want to solder your own connectors.

The UART0-RX signal should be connected to the serial TX line, and the UART0-TX to the serial RX line.

See your USB-serial cable details for wire/pinout.
