  • SP0503 protection safeguards the USB port
  • Three LEDs show TX, RX and power status

USB-C UART Bridge with CP2102

This WaveShare module converts a USB-C port into a 3.3 V logic-level UART using the CP2102 controller. It supplies selectable 5 V or 3.3 V output and includes an SP0503 protection device plus TXD, RXD and power LEDs. The board exposes TXD, RXD, RTS and CTS on standard pin headers for direct prototyping.

Makers, developers and repair technicians

It suits anyone needing a modern USB-C link to serial firmware consoles, microcontroller bootloaders or legacy industrial gear. Buyers who require a USB-A plug, galvanic isolation or voltage levels beyond 3.3 V TTL should choose a different adapter.

CP2102 controller with selectable 5 V

The CP2102 chip provides the USB-to-UART translation and lets you switch the I/O voltage between 5 V and 3.3 V to match the target device. This single setting determines whether the module can drive your circuit safely.

Questions about this item

What pin pitch do the drilled holes use for prototype-board mounting?

The drilled holes match a universal prototype-board pitch so you can solder the module directly onto stripboard or perfboard without adapters.

Which driver package covers Windows 10 and 11 for the CP2102 chip?

Install the Silicon Labs CP210x VCP driver; the device then appears as a standard COM port in Device Manager with no extra configuration.

How can I tell when the on-board protection fuse has tripped?

The POWER LED goes out while the USB host remains connected, indicating the SP0503 has cut power to the UART side.
