Industrial USB TO RS485 Bidirectional Converter, Onboard original CH343G, Multi-Protection Circuits

CH343G is a USB bus adapter chip, which can convert USB to a high-speed asynchronous serial port, supports automatic identification and dynamic self-adaptation of communication baud rate of 115200bps and below, and provides commonly-used MODEM contact signals to expand asynchronous serial ports for computers. It can upgrade a common serial device or MCU directly to a USB bus.

Features At A Glance
1. Support USB to RS485 bidirectional conversion.
2. Onboard original CH343G chip, CH343G is a USB bus adapter chip, which can convert USB to a high-speed asynchronous serial port, supports automatic identification and dynamic self-adaptation of communication baud rate of 115200bps and below, and provides commonly-used MODEM contact signals to expand asynchronous serial ports for computers. It can upgrade a common serial device or MCU directly to a USB bus.
3. Onboard TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, lightningproof & anti-electrostatic.
4. Onboard resettable fuse and protection diodes, ensures the current/voltage stable outputs, provides over-current/over-voltage proof, improves shock resistance.
5. 3 LEDs for indicating the power and transceiver status.
6. Supports Mac, Linux, Android, WinCE, Win11/10/8.1/8/7/XP, etc.
6. Fast communication, stable and reliable, better compatibility.
