A USB-to-UART communication module based on the CH343G chip, offering data rates up to 6 Mbps via a USB-C connector. It supports selectable TTL output levels (3.3 V or 5 V) and works across Windows, macOS, Linux, and Android.
The board includes multiple protection circuits — resettable fuse, transient voltage suppressor, and IO protection — for overcurrent, overvoltage, surge, and ESD protection.
Key Features
- CH343G Chip – Up to 6 Mbps baud rate, supporting 5 V / 3.3 V / 2.5 V / 1.8 V serial I/O levels
- USB-C Connector – Modern, reversible connection
- Selectable TTL Level – Onboard 3.3 V / 5 V switch pins
- Power Output – 3.3 V or 5 V via onboard jumper (USB-powered)
- Multi-OS Support – Windows 7/8/8.1/10/11, macOS, Linux, Android
- Built-in Protection – Resettable fuse, TVS, and IO protection circuits
Ideal For
- Serial debugging and communication
- Microcontroller programming and flashing
- Connecting UART devices to a computer
- High-speed serial data transfer
Package Contents
- 1× CH343 USB UART Board (USB-C)
- 1× 6-pin squid wire
Resources
Jargon buster
Plain-language definitions for the technical terms used above.
- baud
- Baud is the signalling rate of a serial connection, often used as the speed setting for UART communication. Matching the baud rate matters because both connected devices must use the same setting for readable data.
- ESD protection
- ESD protection helps protect electronics from damage caused by static electricity discharges. It is useful on development boards because cables, sensors and modules are often plugged and unplugged during prototyping.
- microcontroller
- A microcontroller is a small computer on a single chip that runs a stored program and controls connected inputs and outputs such as buttons, sensors, displays and communication interfaces. In a device built around one, it is the part that executes the code and coordinates the device's behaviour.
- UART
- UART is a simple asynchronous serial interface that sends data over separate transmit and receive wires, usually labelled TX and RX, with both ends set to the same baud rate. It is a common way for microcontrollers and other serial devices to exchange data.
- USB-C
- USB-C is a small, reversible USB connector that can carry power, data and, on some devices, video over a single cable. The same connector can range from charging only to high-speed data, so the functions a given port actually supports vary.
