The CP2102 USB UART Board (micro) is an accessory board that features the single-chip USB to UART bridge CP2102 onboard. It features Single-Chip USB to UART Data Transfer with no external resistors required, no external crystal required and an on-chip power-on reset circuit and voltage regulator.

The USB suspend states supported via SUSPEND pins and UART has all handshaking and modem interface signals.

This is a great little tool for embedded systems that require a serial connection to a computer. The board can simply attach to a USB bus and will appear as a standard COM port.

Pin connections of FT232 USB UART Board:

  1. VCCIO ↔ 3.3V or 5V output (the module is powered from USB, the onboard jumper should be shorted to 3.3V or 5V)
  2. GND ↔ GND
  3. TXD ↔ MCU.RX (signal direction: MCU.RX << FT232 << PC.TX)
  4. RXD ↔ MCU.TX (signal direction: MCU.TX >> FT232 >> PC.RX)
  5. RTS ↔ MCU.CTS (signal direction: MCU.CTS << FT232 << PC.RTS)
  6. CTS ↔ MCU.RTS (signal direction: MCU.RTS >> FT232 >> PC.CTS)

This breakout also allows you to connect the TX/RX pins of your favorite microcontroller or serial application to the RX/TX pins of the breakout, creating a simple serial cable replacement.
