Serial Console of the HSL Femto

There is a 3-pin header on the digital board of the HSL Femto.

It contains a RS-232 serial console of the TI DaVinci ARM core running at 115,200 bps

The pinout is as follows:
  • Pin 1: TxD output of Femto
  • Pin 2: RxD input of Femto
  • Pin 3: Ground

NOTE: There is a RS232 level shifter on board running the console at real RS232 voltage levels, so don't expect the typical 3.3V CMOS level.
