How do I connect my Raspberry Pi to the serial?
Connect the Raspberry Pi board to a +3.3V serial device.
- To receive data, connect the GPIO 15 (UART0_RXD) pin on the Raspberry Pi board to the TxD pin on the serial device.
- To transmit data, connect the GPIO 14 (UART0_TXD) pin on the Raspberry Pi board to the RxD pin on the serial device.
How do I connect my UART device to my Raspberry Pi?
To connect the Raspberry Pi to a PC via UART, you will need a USB Serial Cable that supports 3.3V. As seen on the image above, this cable has four female wires that can be plugged into the Raspberry Pi. The red wire is to be connected to +5V, black wire to GND, green wire to TXD and white wire to RXD.
