USB to UART Module (Mini-USB) CH343G Chip Support Linux, Android, Windows 7/8/8.1/10/11,Onboard Multiple Protection Circuits

USB to UART Communication Module,mini-USB DEVICE INTERFACE. COMMUNICATION RANGE:50bps ~ 6Mbps. 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 resistance, 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. 1)Indicator description: PWR:Power indicator, turn on when the voltage is detected from USB interface. RXD:Receiving indicator, turn on when data is sent back from the device interface. TXD:Sending indicator, turn on when data is sent from USB. VCC:5V or 3.3V output for external device (configured by jumper). 2)Pinouts Definition: GND:Ground. TXD:Connects to MCU.RXD. RXD:Connects to MCU.TXD. RTS#:Connects to MCU.CTS. CTS#:Connects to MCU.RTS.
