UMFT234XF Development
Module
UMFT234XF is a USB to UART development module
1 Introduction
The UMFT234XF development module utilizes FTDI’s FT234XD IC to convert USB to a basic UART (RXD,
TXD, RTS#, CTS#).
1.1 Features
The UMFT234XF is a development module that converts USB2.0 Full-Speed to UART. The module includes a
micro-B USB connector to connect to a USB host and the UART IO are available on separate pads. The
module is designed to be soldered directly to another PCB (PCB on PCB technology).
The UART interface operates between +1.8V and +3.3V voltage levels depending on the VIO signal, however
all I/Os are 5V tolerant.
An additional configurable bus (CBUS) pad allows for general IO or indicating that the module is connected to
a dedicated charging port for battery charging.
