FoBE Breakout GP8303

I2C 4-20mA/0-20mA DAC Module.​


FoBE Breakout GP8303 Main

Introduction​

FoBE Breakout GP8303 can convert I2C signals into analog signals, and can linearly convert 12-bit digital values 0x000-0xFFF into 4-20mA analog current; the output current linearity is 0.1%.

There is an eeprom on board, can store the calibration parameter.
