【Fast Isolated Transfer】TTL output module with CH340T USB to serial design and optocoupler isolation supports up to 256000bps, helping reduce interference during data transmission for sensitive equipment.
【3.3V And 5V Output】USB to serial TTL output module provides selectable 3.3V or 5V output level. TX RX side includes protection diode function to improve shock resistance in connected circuits.
【Complete Electrical Isolation】PC USB side and serial output side achieve electrical isolation. On board 5V isolated power supply module and 500mA self recovery design help protect the computer during use.
【Practical Module Design】Made of electronic components with maximum 150mA serial output current. On board stable CH340T chip supports consistent connection for debugging control and transmission tasks.
【For Device Connection】Designed to isolate TX RX GND and VCC pins between serial module and user device. Suitable for sensitive equipment transmission setups requiring isolated serial communication.
