USB-TTL_Module

The USB-TTL (Type-A) Converter Board is a compact serial communication module that converts USB signals from a Type-A port into TTL-level UART signals. It provides easy access to TX, RX, GND, 3.3V, and 5V pins, making it ideal for programming, debugging, and serial communication with microcontrollers such as Arduino, ESP8266, ESP32, and STM32 in embedded and prototyping applications.
