PCB of the day! Add oodles of analog inputs with an 8-channel ADC 🔌📊🔧
Many microcontrollers have ADCs these days for reading analog/resistive sensors like potentiometers, thermistors, LDR light sensors, etc., but sometimes you need MOAR! or maybe you're using a single board computer like a Raspberry Pi that has no ADCs at all...the ADS7830 is an affordable 8-channel ADC with I2C interface, so it's easy to include with any platform. There are 2 address pins, so you could have 4 x 8 = 32 total ADC channels with chain-able Stemma QT cables. You can get up to 70 Ksamples per second, but only 8-bits of resolution, so it's suitable for rough sensor measurements. This…
