About

The PocketScreen is the smallest Arduino compatible multitool, whose board is just as big as a coin which includes a Microcontroller, full color OLED screen, Micro SD Card reader, 3 Hotkey Buttons, a status RGB LED and a Charing Module! (And possibly a WIFI module - See "Stretch goals"-section)

 It's like a tiny computer that fits in the palm of your hand.

The PocketScreen combines all important modules to develop great Arduino projects!

Upload your own codes or load sketches or images from a Micro SD card.

Same hardware but half the size of the PocketStar!

The PocketScreen has the same hardware as our previous project, the PocketStar (Except vibration motor and 3 more buttons) but is less than half the size. So most PocketStar projects should also work on the PocketScreen (When it's ported).

Visit our forum to explore already created community projects!

It works completely independent of the breadboard, because all important components and modules are on board.

Click the button below to download all Photos of the PocketScreen in high resolution.

Every important module - In one device!

Display, Microcontroller, Micro SD card connector - Everything you need is built-in. Even a charging module is on board to make portable projects a possible!

No wiring or breadboard needed - Just plug it in and upload your code!

You can connect it and upload your code directly. You don't need a breadboard, but you can still use it to expand your project.

It's just as big as a 50 Cent coin when it's folded

The compact size (25x22 millimeters) allows many portable projects. You can make a custom keychain, smartwatch or necklace out of it. (See "Project Ideas"-section)

Only 5 millimeter thick

Together with a battery, it fits into a ~12mm thick housing.


A full-color OLED screen makes many great projects possible! It only measures 25x22 millimeters which is just as small as the circuit board itself. Despite the small size, you can see many details. 


The Atmel ATSAMD21G18A is the same microcontroller that is used in the PocketStar & Arduino Zero. Enough to display 3D graphics (Real time rendering) & videos on the screen at over 30 FPS.

About ~20 16-bit images (12.288 bytes each) and ~41 8-bit images (6.144 bytes each) would fit into the internal memory. But if that's not enough, you could store thousands or even millions of images and sketches in a Micro-SD card and load it from there.

With a Micro SD Card, you can expand the memory of your project and load sketches without reprogramming every time. There is also a detection pin that checks if an SD card is inserted (That avoids crashes).

*The reason for the long wait at the beginning of the video is that the PocketScreen is trying to load the SD card. (You can avoid this by checking if an SD card is inserted at all)

The Micro SD card connector has a push-push function. That means it pops out when you push the Micro SD card while it's inside.

3 free assignable hotkey Buttons & A Hard-Reset Button.

Via the micro USB port, you can upload new sketches - There is a built-in charging module, which can charge a lithium-polymer battery, if one is connected. This makes portable projects like a watch or keychain possible!

(See the "Project Ideas"-section below)

The charging module allows you to check if the battery is charging and what the battery level is.

With the RGB LED on the board, you can display any color you want.

The breadboard compatible breakout pins gives you the opportunity to extend your project with additional modules and functions. 



Should we achieve the stretch goal of 20,000€ (See stretch goals down below), we will integrate the ESP8266EX WIFI chip.

An integrated WIFI module would make many IoT projects possible. A smartwatch connected to your smartphone or even as a mini server, which takes on a few tasks.

Uploading sketches via WIFI without connecting the PocketScren would be possible!


We already have a plan to create space for the new components:


1. The raw input & VCC will share one ground pin

Currently there are two ground pins. One at the pin header and the other next to the raw input. To create more space, we would put the raw input directly above the ground pin on the header.

2. Remove components & use smalle ones

There are ways to save parts. For the RGB LED 1 instead of 3 resistors can be used.

Currently we use 0603 package size for resistors and capacitors. If we use a smaller size, this should create more space.

3. Four layer PCB

The current board has two layers. If we increase it to four layers, the majority of the connections would be shifted from the surface to the inside of the board, creating more space for components.

4. Micro SD card connector as antenna

The Micro SD card connector would work very well as an antenna replacement, because the exterior is conductive and not connected anywhere.


Library

The library will be very similar to the PocketStar library, as it has almost the same hardware, with the difference that you can also control the pins. So it's easy for beginners.

(Click here to see the documentation of the PocketStar library)

Sketch-Loader

With the sketch-loader, you can switch between programs without reprogramming every time.

Apps ported from the PocketStar 

  • Stopwatch
  • Score Tracker
  • Dice
  • Counter
  • Random generator

Visit our Website to take a look at the current Apps.

Image converter

With the image converter, you are able to convert your images into files that can be read from the SD card (.psi) as well as convert it into code for Arduino.

Many great projects are possible with the PocketScreen. The 3D (.stl) templates will be provided on our Website.


If the project goes beyond the goal, we will make improvements/changes as soon as the following goals are achieved: 



With the help of the Arduino community, we can collect enough pledges on Kickstarter so we can offer the PocketScreen at a reasonable price.

Please keep in mind that the project can only be implemented, if we reach the funding goal within 30 days.

Risks and challenges

Unlike our first project, the PocketScreen is a finished prototype and ready for production. But if we add the WIFI module, the delivery could be delayed by about one month because we still need to test the improved device. There shouldn't be big problems since the basic design is tested and ready to use.

Thanks to our first Kickstarter campaign, we have learned a lot and now have reliable partner companies and suppliers. There will probably be no delays in production.
