The FT232RL USB to serial UART converter is very useful in connecting the computer to the microcontroller.
The USB UART converter is a device that converts the USB data transmission protocol to UART and vice versa. It is very often used to connect your computer to development boards or directly to microcontrollers.
This product uses the FT232RL integrated circuit, of very good quality and small size, found in the SMD package. The circuit also includes a 3.3 V regulator and a jumper allowing you to switch between 3.3 V and 5 V. There are also LEDs on the circuit indicating: power, reception and transmission of data.
Baud rate is adjustable. Do not forget to install the necessary driver on your computer.
