The USB to UART TTL Serial Converter Module is a handy interface that converts your computer’s USB port to a standard UART (TX/RX) serial port. It is ideal for programming, flashing firmware and debugging microcontroller-based boards such as Arduino, ESP8266, ESP32, STM32 and many other embedded devices. The module breaks out 3.3V, TXD, RXD, GND and +5V pins on a convenient 5-pin header, making it simple to connect with jumper wires. Just plug the module into your USB port, install the required driver (if needed) and you can start using any serial terminal or IDE to communicate with your hardware.
