CP2102 USB UART Board (USB-A)

This small board makes communication between a computer's USB port and UART devices a piece of cake! It uses the CP2102 chip, a single-chip USB-to-UART bridge, which eliminates the need for external components like resistors. It has a 576-byte receive buffer and a 640-byte transmit buffer for data transmission. It is compatible with many operating systems, including Windows (from Windows 2000 to Windows 11), Mac OS-X/OS-9, Linux 2.40 or higher and Android. This version of the module includes a USB-A connection and comes with pin headers and a jumper wire. We also stock a USB-C and Micro-USB version. Features

Pinout MCU

* VCCIO: 3.3V or 5V output (the module is powered from USB, the 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)
