CH347 USB Interface Development Board

Connect several digital interfaces to a USB host with a CH347 development bridge board for electronics prototyping.

✅ Bring different buses to one bench - The board supports the described I2C, SPI, UART, JTAG and GPIO interface functions.

✅ Select the working mode locally - Two switches provide the described mode selection for the bridge configuration.

✅ Choose the connection package - Board-only and board-with-cable selections let you match the kit to existing leads.

Give the computer a path to your circuit

A computer does not normally expose the same connections as a small embedded board. A USB bridge provides an interface between host software and a correctly wired target circuit.

Select the correct mode, driver and signal configuration before connecting the target. USB link speed is not the transfer rate of every attached bus, and the target's voltage levels and pinout must match the board.
