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

We are introducing a professional RPi compatible tablet

Update: Power over ethernet (PoE) ready
 

In opposite to the many DIY builts and available kits, the HackerTab comes fully assembled and ready to run - but you can get a bare-bone option as well.

Instead of just stuffing a hobby-grade Raspberry Pi inside a monitor, we designed a real tablet from scratch which is running on the Raspberry Pi CM3 (Compute Module).

The CM3 is a tiny module containing the same processor as the RPi model 3B+ (four cores), but it´s intended to be used in industrial environments like fuse boxes and electrical cabinets.

The HackerTab is a fully integrated solution. The form factor is very handy and compact, yet offers plenty of space inside for expansions and integration of your own systems.

The removable silicone shell provides drop protection and splash water resistance.

Our goals

We designed a product which is meant to be a carrier for your own system.
You can focus on your goal instead of struggling with integrating a power management, a touchscreen, audio etc.

You can plug in your own (or third party) board into the standard Pi-HAT header and you are ready to go.
There are already many boards available, for example motor control, Hi-Fi audio, LTE connectivity and many many more.
The size of your custom board can be even greater than the size of a Pi-HAT. In fact, you can use the whole area inside the tablet. And you are free to sell your own products using this device as basis.

Some ideas are:

  • Entertainment system in the car
  • Arcade game machine
  • Portable oscilloscope
  • Outdoor SDR / Radar / GPS
  • Industrial control
  • Interactive terminal

What does "professional" mean?

  • Fully assembled device - ready to run
  • Body developed by professional industrial designer
  • Long-year experience in electronic design
    and series production
  • Power-down by system command
  • Splash-proof
  • Outdoor-capable
  • Realtime clock (can wake up the tablet)
  • Panel- & wall-mounting
  • Customized ISO/TS16949 automotive TFT panel
  • Using only quality components
  • Integrated power system
  • Audio IN and OUT (the standard RPi has output only)
  • CM3 or CM3 LITE module inside
  • Meets RPi HAT specification
  • HACKABLE

Device is ready-to-run
No further assembly needed

Price comparison

Let´s compare the price with a DIY-Kit

  • Raspberry Pi 3B+ 35€
  • Official Touchscreen 70€
  • Case 25€
  • Powerbank 10€
  • Audio IN 15€
  • Realtime clock 10€ 

SUM: 165€

So for only 84€ more you´ll get:

  • Handy format, but plenty of space inside
  • Rugged case / splash resistant
  • Header is free for use (no power or audio shield needed)
  • Power monitoring
  • USB accessible from inside
  • Space for your project instead of stuffed wires

Technical Data

Size: 19cm x 12cm x 3cm
Display: 7", 1024x600 Pixels RGB, touchscreen
CPU: Raspberry CM3 or CM3 LITE
Power: Li-Ion 3.7V / 5200 mAh / Connector Molex 5268-02A
Consumption: 1200mA typical on CM3
Quiescent current: 200µA max.
Charging: micro-USB, 500mA / 3000mA (autodetect)
Audio: 3.5mm jack, line/mic in, line out, internal speaker 1.5W
Interfaces:4x USB internal (header), two of them external as USB-A,
LAN, audio in/out, micro-USB (charge/boot),
Pi-HAT header (full GPIO Bank0), camera, power, speaker,
Updated: Header for PoE module, modules will be compliant with PoE standard and low cost.

Details

Audio OUT via 3.5mm jack - using PWM (stereo)  

 - well filtered, good quality sound with no crackling or hissing  

Audio IN stereo (24bit / 96kHz) via same 3.5mm jack  

 - selectable gain 0dB (line in) / +15dB (microphone)  
 - using I2S bus
 - each audio channel (L/R) configurable either as input or output 

Internal speaker with amplifier
 - stereo to mono hardware downmix

Realtime Clock

- RasClock compatible
- time selectable Auto Power OFF   - time selectable Auto Power ON

Battery charging via microUSB 

 - autodetect low/high current charger (similar to a smartphone)
 - charging possible during normal operation
 - USB boot via microUSB possible (for programming eMMC)

Pushbutton for ON/OFF control
 - Push ON / Push OFF

Battery voltage monitor

100 Mbit LAN 

4 USB ports, 2 of them as external USB-A (full sized) 

 - All USB ports accessible through internal 2.54mm pin-headers

Micro-SD slot, to use with CM3 LITE

Pi HAT header
 (standard) to use existing available HATs

Camera interface

- Compatible with existing RPi cameras

7" color TFT 1024x600 pixels 

 - capacitive multitouch
 - constant current dimmable backlight (no PWM, flicker free)

Vesa mount (interface for wall mounting)

Panel mount capability 

Silicone protective shell (removable)

Plenty of space inside

 - plug in your own boards
 - use it as a carrier for your DIY or commercial product

Plug-In WiFi module will be available on demand

- can be plugged into the internal USB header
- will be included depending on the pledge amount

Hackability

- We will provide descriptions of various test points and modding tips to give you more control over the hardware

Risks and challenges

We have a working prototype which has been tested for long time without showing any trouble.
The casing of the prototype has been 3D printed with laser-sintering to fit-check the injection-mould CAD data.
The device is ready for production i.e. PCBs, casing, assembly, packaging and shipping.
We have all quotations, so all we need is to press the start button.
Although we are using only reliable parts with high availability, there is currently a shortage of high capacitance ceramic SMD capacitors on the world market. We are trying to compensate for that and get all tapes before the campaign is over, so we can start production as soon as the fundraising goal has been reached.
