I2C/SPI - UART 인터페이스 변환 모듈
(I2C/SPI-to-UART Breakout - SC16IS750)
.
개요
- 본 제품은 I2C 혹은 SPI 시리얼 인터페이스를 UART 인터페이스로 변환하여 주는 제품입니다.
- SC16IS750칩을 장착하고 있으며, 마이크로컨트롤러의 부족한 UART인터페이스를 늘리고자 할 때 사용할 수 있는 제품입니다.
- 보드 뒷면의 솔더 점퍼를 이용하여 I2C 주소를 설정할 수 있습니다.

It does not come with pin headers. Please purchase and solder the pin header appropriate for your intended use.
About I2C address:
By cutting and connecting A0 and A1 jumper pad on the back of the breakout board, you can change I2C address. A0 is connected to VDD, A1 is connected to VSS at the initial setting, and the address is 0x98(1001 100X). Please refer to the IC data sheet regarding other settings.
About I2C pull-up register:
By soldering the 1608 size resistor chip to the R3 and R4 on the back of the board, you can pull-up the I2C signal line with supply voltage (3V3 terminal). R3 pulls-up SDA, R4 pulls-up SCL.
Please acquire separately the pull-up resistor (size 1608) and solder it as needed. As the distance between the resistor and the header is quite short, it is easier to mount the resistor first.
