What is a prototype?

A prototype is a preliminary model of something. Projects that offer physical products need to show backers documentation of a working prototype. This gallery features photos, videos, and other visual documentation that will give backers a sense of what’s been accomplished so far and what’s left to do. Though the development process can vary for each project, these are the stages we typically see:

Proof of Concept

Explorations that test ideas and functionality.

Functional Prototype

Demonstrates the functionality of the final product, but looks different.

Appearance Prototype

Looks like the final product, but is not functional.

Design Prototype

Appearance and function match the final product, but is made with different manufacturing methods.

Production Prototype

Appearance, function, and manufacturing methods match the final product.

These photos and videos provide a detailed look at this project’s development.

Universal Zero is an 8 port DAC / ADC / GPIO expansion pHat. 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. Any of the 8 pins can act as ADC (analog input), DAC (analog output) or GPIOs . It is possible create almost any

  • weather station
  • voltmeter
  • parts tester
  • digital thermometer
  • robot
  • almost any embedded device

Tou 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)

Ultimate Zero uses only 4 Raspberry Pi pins giving you 8 universal digital and analog inputs and outputs.

Extremely Easy to Code

Just couple lines of code required. Python & C library provided

Universal Zero has 54 pin proto area for rapid prototyping

3.3V , 5V & plenty of GND available. Test your ideas on the hat.

Board Layout

Universal Zero PCB layout. Please always set Vcc to 3.3V.
Universal Zero PCB layout. Please always set Vcc to 3.3V.

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.

Some Easy Soldering Required 

Universal Zero comes with all SMD parts soldered. Headers and optional output buffer socket has to be soldered.

Risks and challenges

The board is ready, software is ready, so there should be very low risk associated with this project. It was beta tested. Parts are available. We source our PCBs, materials and parts in Europe.
