Need to add analog inputs? This chip will add 8 channels of 10-bit analog 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 it's fun to have analog inputs but the Pi does not have an ADC. https://elecena.pl/product/17498347/mcp3008-8-channel-10-bit-adc-with-spi-interface 2021-04-06 https://elecena.pl/product/17498347/mcp3008-8-channel-10-bit-adc-with-spi-interface 2021-12-15
