USB To UART Communication Module, Micro / Mini / Type-A / Type-C Connectors, High Baud Rate Transmission

USB to UART Communication Module

Stable transmission | Multi-device applicable | Multi-system compatible

Features at a glance

• Adopts new version CH343G chip. Compared with CH340G, it supports higher data rate (up to 6Mbps) and more serial port IO levels (5V / 3.3V / 2.5V / 1.8V)
• Supports Mac, Linux, Android, Windows 7/8/8.1/10/11
• Onboard resettable Fuse and Transient Voltage Suppressor, anti-overcurrent and anti-overvoltage, anti-surge, anti-static, improve shock proof performance, stable and safe communication performance
• Onboard IO protection circuits, anti-surge, anti-static, stable and safe communication performance
• Onboard 3.3V and 5V TTL level switch pins for selecting TTL communication level
• Support 3.3V/5V output (the module is powered by USB, and the onboard jumper should be shorted to 3.3V or 5V accordingly)
• Adopts double-sided black immersion gold process, which is durable and has a good look
