Description

  • 8 x 17-bit 0 to 5V Single Ended Inputs
  • Control via the Raspberry Pi I2C port
  • Stack up to 4 ADC Pi Zero boards on a single Raspberry Pi
  • Jumper selectable I2C addresses
  • Buffered 5V I2C port

The 8 Channel 17-bit Analog to Digital Converter for Raspberry Pi Zero is an 8 channel 17 bit analog to digital converter designed to work with the Raspberry Pi Zero. The ADC Pi Zero is based on two Microchip MCP3424 A/D converters each containing 4 analog inputs.  The MCP3424 is a delta-sigma A/D converter with low noise differential inputs.

The ADC Pi Zero is powered through the host Raspberry Pi Zero using the GPIO port and extended pins on the GPIO connector allow you to stack the ADC Pi Zero along with other expansion boards.
