DIYMAT001

  Universal Zero DIYMAT001  Universal Zero is an 8 port DAC / ADC / GPIO expansion board. Fits any 40 pin Raspberry Pi       read up to 8 analog 12 bit inputs (ADC)   write up to 8 analog 12 bit outputs (DAC)   read or write up to 8 digital channels (GPIO)   internal thermometer   fast 25MHz SPI, 400kSPS ADC  internal 2.5V (or 2x 2.5V) or external 3.3V ADC & DAC Voltage reference  It is fully software configurable (find the libraries here) https://github.com/diymat/UniversalZero Any of the 8 pins can act as ADC (analog input), DAC (analog output) or GPIOs . Possibly projects include       weather station  voltmeter  parts tester  digital thermometer  robot  almost any embedded device  You can:        control engines   read potentiometers   read joysticks and dials   read analog and digital sensors  provide signals for analog circuits  act as a digital potentiometer   read and write any signal (analog or digital)  Board Layout https://cdn.shopify.com/s/files/1/0174/1800/files/mnl.pdf?15815831175326407072 The board’s ADC/DAC/GPIO IC can be supplied from 5V (jumper 8). It gives a potential possibility to measure directly voltages up to 5V (up to Vcc actually). This is an experimental feature, and it is very probable to damage your PI if the 5V option is used. Please always use 3.3V option.                                                                         https://shop.pimoroni.com/products/universal‐zero  4/17/2017
