USB to UART TTL Serial Adaptor

USB to UART TTL Serial Adapter – USB to Serial Converter Module for Microcontroller Communication

The USB to UART TTL Serial Adapter is a compact and essential module that provides seamless communication between your computer and serial-based microcontrollers like Arduino, ESP8266, ESP32, STM32, and more. Based on popular chips like CH340, CP2102, or FT232RL, this adapter converts USB signals to TTL-level UART (TX/RX) signals, allowing easy firmware uploading, debugging, and serial communication.

It features standard 6-pin or 4-pin headers with TXD, RXD, VCC, GND, and often DTR or RTS for automatic reset when programming devices. Plug-and-play via USB, it supports multiple baud rates and is compatible with Windows, Linux, and macOS.
