Madefree Breakout Single UART with I²C/SPI Interface
This is a Breakout board of SC16IS750 chip.
The SC16IS740/750/760 is a slave I2C-bus/SPI interface to a single-channel high performance UART.
It offers data rates up to 5 Mbit/s and guarantees low operating and sleeping current.
The SC16IS750 and SC16IS760 also provide the application with 8 additional programmable I/O pins.
Dimension: 26×26 mm
