Product Details

UM232R USB to Serial UART Development Module, FTDI Chip

The UM232R module is a USB - Serial UART (TTL) development module for the FT232R IC device. The UM232R is supplied on a PCB designed to fit a 24 pin DIP socket, and provides access to all UART and CBUS interface pins of the FT232R device. The UM232R can be configured as either USB bus-powered or self-powered and also supports 5V or 3V level interface IOs via two sets of jumper setting pins. Full hardware handshaking is supported and the UM232R can communicate at up to 3MBaud at TTL/CMOS levels.

FTDI Chip USB To UART Development Board

The FTDI chip USB to UART development board is a development module that uses FTDI’s FT232RL, one of FTDI’s range of USB to UART interface integrated circuit devices. The FT232RL is a USB to serial UART interface with optional clock generator output and the FTDI Chip-ID security dongle feature. The internally generated clock (6MHz, 12MHz, 24MHz, and 48MHz) can be detached and used to drive a microcontroller or external logic. A unique number is burnt into the device during manufacture and is readable over USB, thus forming the basis of a security dongle that can be used to protect customer application software from being copied. The circuit is supplied on a PCB which is designed to plug into a standard 0.6in wide 24-pin DIP socket.
