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.

About

Complete Solution

The world doesn't need another embedded processor board; it needs a complete solution: circuit board, display, I/O, software and enclosure.

That's why we designed the PDK-64.

Display: This is the first (and often) only aspect of your product that the end user will ever see. If it's not sharp, fast and easy to see, people will think your product is junk. That's why we went with a sunlight readable (450 nit) TFT display. It sports a multi-touch glass Capacitive Touch screen for fast response. 

PCB: Based on the All Winner A-64, quad-core. It runs at 1.2 GHz and has one Gigabyte of RAM and 8 Gbytes of FLASH. Of course, it's got all the other standard peripherals, see the list below.

Chassis: we took an “old school” approach and built the entire unit around a cast aluminum frame. It provides a rugged base to build your project around: bolt to it, screw into it, glue to it, even machine it.

Basic Bezel: the chassis comes with a basic bezel to hold the TFT and Touch Panel in place while sitting on your bench. Use your imagination, you'll find plenty of ways to use it. 

Enclosure: Just because it's tough, doesn't mean it can't be pretty. We've also designed a customizable enclosure. This is were plastic makes the most sense: tough enough to protect but flexible enough to absorb the trauma of the real world. Knock-out panels allow you to customize for your project requirements.

The enclosure features removable panels to make customization easy.

Main board:  

  • Quad-core A8 running at 1.2 GHz
  • 1 Gbyte RAM
  • 8 Gbytes FLASH
  •  HDMI output
  •  2 USB Ports
  • uSD Card for addition storage
  • Wifi (on board)
  • Ethernet MAC
  •  Camera interface
  •  TFT/Touch panel interface
  • 5 Watt stereo output
  •  Pi bus connector
  •  Euler bus connector
  • battery connector for on-board charging circuit
  • Microphone input
  • 6 switch inputs
  • Options: Ethernet PHY module; 4 port USB hub

Display:

  • 7" TFT, sunlight readable (450 nit)
  • Capacitive touch screen.

Okay, this isn't the greatest photo ever taken but it gets the idea across. Here's the display outside in the Denver sun at 2:00 in the afternoon. (Shown running Android 6.)


  I/O board:

We're designing a general purpose I/O board that will simply bolt to the frame and allow you to interface to the real world right away. General features are:

  • Four general purpose 2 A, low voltage relays
  • 8 current sync pins
  • 8 buffered inputs
  • prototype area
  • Arduino shield compatible connector footprints
  • configurable connectors for I2C, SPI, Serial bus etc

Please remember that the above specs might change based on feedback from backers.

Of course, software drivers will be provided.

Software:

Comes with Linux, Code::blocks development app and GNU compiler installed. Just add a keyboard and start developing. (Of course, an HDMI monitor and mouse make life easier.)

Android image will be available.

Mechanical:

Cast aluminum chassis: 6.7” x 3.9” x 0.87” Fits into the Retro-modern ABS enclosure: 9.6” x 5.65” x 1.45”

Risks and challenges

Of course, standard disclaimers apply. That said, there isn't anything new here! In fact, most of the software drivers already exist; the TFT panel is OTS and the custom Touch panel only needs minor tweaks.

The biggest challenge will be managing all the little details to bring everything together at the same time and at the same place.
