Do you need more analog inputs with your Arduino? Want to add the ability to read analog sensors to your Raspberry Pi? The MCP3008 is designed to do just that! This integrated circuit can accept 8 analog inputs (or 4 pseudo-differential pairs) with 10 bit precision and only requires 4 wires to connect over the SPI bus. This is the same chipset we use with our Raspberry Pi 16 Channel Analog Input HAT.
