Konwerter USB UART TTL CH340G 3V3 5V USB-A programator do Arduino ESP32

USB UART TTL Converter with CH340G 3.3V 5V USB-A Professional USB to UART converter (Universal Asynchronous Receiver-Transmitter) enabling bidirectional data transmission between a computer with a USB-A port and devices equipped with a serial interface. The module is based on the popular and reliable CH340G chip. The device emulates a virtual COM port in the operating system, allowing easy communication with microcontrollers. The module is fully compatible with popular development platforms. It works perfectly as a programmer for ESP8266, ESP32, Arduino, and Raspberry Pi. Key technical features

* Control chip: CH340G

* Communication interface: UART

* Logic level voltage: 3.3V and 5V - selectable via a jumper

* Computer connector: standard USB-A plug

* Status indication: built-in LEDs (power, TX transmit, RX receive)

* Additional pins: RTS (Request to Send) and CTS (Clear to Send)

* Module dimensions: 59 mm x 24 mm

Example applications

* Programming microcontrollers without a built-in USB interface (e.g. for Arduino Pro Mini)

* Uploading firmware to WiFi modules (for ESP8266, for ESP32)

* Serial communication with single-board computers (for Raspberry Pi)

* Diagnostics of network devices (routers, switches) via the console port

* Reading data from sensors and modules equipped with a UART interface

* Creating custom diagnostic interfaces in electronic projects

Benefits of using the module

* Voltage versatility - ability to work with 3.3V and 5V circuits thanks to the built-in jumper

* Visual operation monitoring - LEDs indicate power and ongoing data transmission

* Full flow control - exposed RTS and CTS pins enable hardware transmission control

* Complete kit - the package includes the necessary jumper and 4 connection wires (female-female)

* Easy installation - the module requires only the standard ch341ser driver (recommended for Windows systems)
