This is a breakout board for the SC16IS750, a useful chip to convert I2C or SPI serial signals to a single-channel, high-performance UART. As an application example: Sparkfun uses this chip on their 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 lets you use 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 the board should work well with both 3.3V and 5V controllers.
This board breaks out all pins of the SC16IS750 to two breadboard friendly 11-pin, 0.1" pitch headers.
Dimensions: 27.9x22.9mm (1.10x0.90")
