RPI-ADC-1 | 8-Channel Analogue to Digital Converter for Pi
Need to add analogue inputs?
This chip will add 8 channels of 10-bit analogue input to your microcontroller or microcomputer project. It's super easy to use, and uses SPI so only 4 pins are required. We chose this chip as a great accompaniment to the Raspberry Pi computer, because its fun to have analoguge inputs but the Pi does not have a built-in ADC.
