Test serial communication in between Raspberry Pi and PC

To test whether our Serial communication is working or not make the connections shown in the below figure.

Raspberry Pi Interface with PC/Laptop for Serial Communication

Open Terminal on Laptop/PC to receive the data which will be transmitted from the Raspberry Pi.

Now, enter the following command to transmit data from Raspberry Pi terminal.

echo “Hello” > /dev/ttyS0

This command will output the “Hello” string on the UART port i.e. Tx pin and will display it on the terminal application of the PC/Laptop.

By default, mini UART is mapped to the GPIO14 (TX) and GPIO15(RX). While PL011 i.e. ttyAMA0 is connected to the onboard Bluetooth module.

Package Included: Pi-232 HAT x1, Screwdriver x1, Screws packx1, Quick Start x1. The Serial HAT features a Male DB9 RS232 port connected to the Pi's UART pins via a ST3232 IC. The ST3232 IC converts the Pi's UART port to RS232, which enables serial communication with any RS232 compatible serial device !. Serial Interfact HAT for the Raspberry Pi A+/B+/2/3/4(Also works with Zero/Zero W), HAT compliant (No EEPROM), Male DB9 Socket (RS232/ RS-232), ST3232 IC, TX/RX/GND Solder Points. Expansion board size: 65mm*56.5mm, the standard Raspberry Pi HAT extension plate size. A standard RS232 serial port can be connected directly to the PC etc.
