Free up your UART interface with the I2C/SPI-UART SC16IS750 Breakout Board!

The SC16IS750 Breakout Board is, as its name suggests, equipped with the circuit of the same name, used to convert an I2C/SPI signal into a UART serial signal. Why choose a communication via your I2C/ SPI interface rather than the UART on your Arduino board?

First of all, by so doing you free up the UART interface on your Arduino board, allowing you to save it for connecting other modules.
Second, using an SPI or I2C interface to communicate with Arduino modules normally intended for a UART protocol speeds up data transmission.

In short, you save time and space!

Technical schematic of the I2C/SPI-UART SC16IS750 Breakout Board

Your IC I2C/SPI-UART SC16IS750 Breakout Board is powered via its VIN pin; the current then passes through a 3.3 V LDO (low-dropout) regulator, which regulates the output voltage even if it’s very similar to the input voltage.

Note too that the breakout board is also 5 V tolerant, making it compatible with a wide range of microcontrollers.

A new version of the I2C/SPI-UART SC16IS750 Breakout Board

This breakout board is actually a newer version of a product offering similar functionalities, equipped with the same SC16IS750 circuit.

However, this older version had a 12.288 MHz crystal oscillator compared with 14.7456 MHz in the current version, which increases the range of baud rates (from 9600 to 921600 baud).

Technical specifications of the I2C/SPI-UART SC16IS750 Breakout Board

  • Number of pins: 2 x 11
  • RoHS compliant
  • Dimensions: 27.9 × 22.9 mm
  • Compatible with 3.3 and 5 V microcontrollers
