Product description: CP2102N USB-UART converter - with microUSB connector - Pololu 1317
A module based on the CP2102 chip, which enables data conversion between USB-UART standards. With this converter you can exchange data between a PC equipped with USB port and a microcontroller supporting the popular serial interface. The module has a built-in microUSB connector. Additionally, the chip contains four general purpose digital outputs (GPIO).
For proper work of the converter a microUSB cable is required, which is not included in set. You can buy it separately in our shop.
Pinout description of the converter.
Pinout description
Pinouts of the converter are popular goldpin connectors with 2,54 mm pitch. They allow to connect the module with wires or allow direct PCB plugging. In addition, the converter has four digital GPIO pins, which can be controlled by one-time programming ROM.
- VDD - regulator output with voltage of 3.3 V
- VBUS - USB bus voltage 5 V
- GND - system ground
- RST - RESET pin
- TX - serial data transmission pin UART
- RX - UART serial data receive pin
- CTS - "Clear to send" control input (used with RTS pin)
- RTS - "Ready to send" control output (used with CTS pin)
- DSR - "Data set ready" control input (activated by low state; used with the DTR pin)
- DTR - "Data terminal ready" control input (activated by high state; used with the DSR pin)
- DCD - "Data carrier detect" control input (activated with low state)
- RI - "Ring indicator" control input (activated by low state)
- GPIO.0 / GPIO. 1 / GPIO. 2 / GPIO .3 - general purpose digital input / output pins
