PCB of the day! Add oodles of analog inputs with an 8-channel ADC 🔌📊🔧
from Adafruit Industries · host Adafruit Industries
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 would be a great way to add a ton of potentiometers to a build, especially if it contained a Raspberry Pi, prototype coming soon! https://www.digikey.com/short/5t1w37hb Visit the Adafruit shop online - http://www.adafruit.com ----------------------------------------- LIVE CHAT IS HERE! http://adafru.it/discord Subscribe to Adafruit on YouTube: http://adafru.it/subscribe New tutorials on the Adafruit Learning System: http://learn.adafruit.com/ ----------------------------------------- #adafruit #electronics #pcb #opensource #opensourcehardware #pcboftheday #analoginputs #8channeladc #microcontrollers #raspberrypi #ads7830 #i2cinterface #sensorreadings #stemmqt #70ksamples #potentiometerbuild
