CH340 USB UART Interface for Communication

CANADUINO CH340 USB UART Interface is a USB-to-serial adapter based on the CH340 chipset, designed to connect microcontrollers and electronic modules to a computer via USB. It supports both 3.3 V and 5 V TTL logic levels, making it suitable for a wide range of applications in programming, debugging, and data communication.

• Chipset: CH340
• Interface: USB to UART (TTL serial)
• Logic level selection: 3.3 V or 5 V
• Connections: TX, RX, VCC, GND, DTR
• Provides power to target device during programming (3.3 V or 5 V selectable)

Compatible with Arduino, ESP8266, ESP32, STM32, Raspberry Pi (UART pins), and other development boards

USB drivers available for Windows, macOS, and Linux

The adapter allows a computer to program or monitor microcontrollers and modules directly via UART. It can also be used as a USB to RS232 interface if the connected device accepts TTL levels. For devices requiring true RS232 voltage levels, a separate RS232-to-TTL converter can be added.

A reliable tool for hobbyists, engineers, and developers working with microcontroller systems.
