Connecting the rpi_ui to a USB to TTL console cable.

The console cable manual show the following connection diagram:

RPI Console pins.png

Our boards break out the uart pins on a 4-pin uart connector.

Here is a diagram (top view) of the rpi_ui. Even if it might show the 16x2, the 20x4 board has the pins in exactly the same order.

So to connect things up:

  • Connect the black GROUND connector to the GND pin. The one nearest the I2C connector.
  • Connect the green RXD cable to the next pin and
  • Connect the white TXD cable to the third pin.

You can leave the red VCC connector unconnected.
