Dear customers, due to the Labour Day, the factories will be closed from 1st to 7th May 2024.
Features
1. Adopt 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)
2. Support Mac, Linux, Android, Windows 7/8/8.1/10/11
3. Onboard resettable Fuse and Transient Voltage Suppressor, anti-overcurrent and anti-overvoltage, anti-surge, anti-static, improve shock resistance, stable and safe communication performance
4. Onboard IO protection circuits, anti-surge, anti-static, stable and safe communication performance
5. Onboard 3.3V and 5V TTL level switch pins for selecting TTL communication level
6. Support 3.3V/5V output (the module is powered by USB, and the onboard jumper should be shorted to 3.3V or 5V accordingly)
7. Adopt double-sided black immersion gold process, which is durable and has a good look
Indictor Description
