LC234X: USB to UART Bridge


The LC234X module is a low cost USB to UART bridge using the FTDI FT234XD to transfer data at up to 3M Baud. Ideal for programming Arduino Pro, ESP modules etc., the pinout follows the industry standard FTDI TTL cable interface. In addition to the 4 data lines (RXD, TXD, RTS, CTS) there is also the option to output 5V power to external hardware. The interface IO level may be set to either 3.3V or 5V by an on-board jumper – no soldering / de-soldering required.

The LC234X module’s UART interface is mapped to one 1X6 pin header. The module is supplied with one right angle socket and one right angle pin header for maximum flexibility.

Furthermore there is an LED provided to indicate data transmission on the UART signals.
