The UB232R is a mini development module for the FT232RQ IC device. It come on a 14mm x 17 mm PCB with a mini B USB connector, and provides USB - Serial UART interface in a extremely small form factor. It is ideal for new development purposes, and also for adding a USB interface to existing product designs.

Based on the FT232RQ device, the UB232R supports RTS/CTS hardware handshaking and is powered from the USB port. Serial data communication is possible at up to 3MBaud at TTL level. In addition, two of the EEPROM configurable CBUS pins of the FT232R are brought out allowing the MM232R to be used to provide clock signals to external logic.

Two 1x4 board headers with a standard 0.1" pitch are supplied with the MM232R to allow for rapid prototyping and development.
