Description
The Waveshare USB to Serial Port Expansion Board is a versatile 4-port USB hub designed to significantly enhance the peripheral connectivity of your Raspberry Pi. It delivers four additional USB 2.0 compliant ports, making it ideal for connecting multiple USB devices such as keyboards, mice, flash drives, or other sensors to your single board computer. This expansion is particularly beneficial for Raspberry Pi models with limited native USB ports, like the Raspberry Pi Zero series.
Beyond its function as a USB hub, this board features an integrated USB to UART converter. Powered by a reliable CP2102 chip, this converter simplifies serial communication and debugging for your Raspberry Pi. A convenient enable/disable switch ensures that the UART functionality can be toggled to avoid conflicts when not in use. The board also includes multiple LED indicators for power, UART status, and individual USB port activity, providing clear visual feedback on its operational state. While its form factor is perfectly suited for Raspberry Pi Zero, Zero W, and Zero WH, it remains compatible with other Raspberry Pi models (B+, 2B, 3B, 3B+, 4B) via a standard Micro USB cable connection.
