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 chip that runs your program and controls connected inputs and outputs. For this product, it is the part that reads buttons and sensors, drives the display and speaker, and communicates over Bluetooth.
- UART
- UART is a simple serial connection that sends data over separate transmit and receive wires, often labelled TX and RX. It matters because this module is designed to replace a wired UART cable with a wireless link while keeping the same serial data format.
- USB-C
- A modern reversible USB connector used for power and data connections. On this product it matters because it can connect directly to a computer as well as to a microcontroller project.
