Description: Replacement:BOB-09981. The new version has a different crystal. We went from a 12.288MHz to a 14.7456MHz crystal. This page is for reference only. The change of crystal increases the functionality of the board by allowing for all of the common baud rates from 9600 up to 921600 (14400, 38400, etc.).
This is a breakout board for the SC16IS750, a handy chip used to convert I2C or SPI serial signals to a single-channel, high-performance UART. As an application example: we use this chip on our WiFly Shield to allow an Arduino to communicate with the WiFly RN-131G module - which is normally controlled via a UART - using an SPI interface. This allows for greater communication speeds and frees up the Arduino’s UART for other purposes.
Power applied to the ‘VIN’ pin is sent through a 3.3V LDO regulator before powering the IC. The input pins of the SC16IS750 are 5.5V tolerant, so this board should work with both 3.3V and 5V controllers. Also populated on the board is a 12.288MHz crystal, to serve as a clock input to the chip, and other supporting components.
This board breaks out all pins of the SC16IS750 to two breadboard friendly 11-pin, 0.1" pitch headers.
