Signals: RxD, TxD, RTS, CTS, and supply lines (PWR, GND) brought out to a 6-pin goldpin header. PWR voltage output level is chosen using a jumper and can be either:

  • 5V supplied from the USB through polymer fuse preventing port damage (max. 500mA)
  • 3.3V supplied from the internal FTDI voltage converter (max. 50mA)

In addition, other transmission signals (RI, DTR, DSR, DCD) are brought out to the solder pads. You can use them if you need a more complex transmission management. Configurable CBUS pins (C2, C3, C4) are also brought out to the solder pads (suitable for goldpin connector soldering).
