CP2102 USB UART Board (Micro-USB)

This CP2102 USB Board is a handy UART accessory for communicating with devices, that features the single-chip USB to UART bridge CP2102 onboard.

This version of the module includes a micro-USB connection and comes with pin headers and jumper wires. We also stock a USB-C version.

Note: the module is compatible with TTL level only, to avoid damage please do not directly connect to an RS232 circuit.

How to Use

Please also see the product Wiki

In the case of working with a MCU:

• VCCIO: 3.3V or 5V output (the module is powered from USB, onboard jumper should be shorted to 3.3V or 5V)
• GND: connects to GND
• TXD: connects to MCU.RX (signal direction: MCU.RX << CP2102 << PC.TX)
• RXD: connects to MCU.TX (signal direction: MCU.TX >> CP2102 >> PC.RX)
• RTS: connects to MCU.CTS (signal direction: MCU.CTS << CP2102 << PC.RTS)
• CTS: connects to MCU.RTS (signal direction: MCU.RTS >> CP2102 >> PC.CTS)

Note: VCP examples and USBXpress driver program library are provided.
