Connecting the rpi_ui to a USB to TTL console cable.
The console cable manual show the following connection diagram:
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.
