The latest Arduino accessory from the guys at TinyCircuits is getting close to the end of its funding campaign on kickstarter but nobody there is getting stressed that they wont get funded; they have already been pledged seven times their goal of $15,000. The team have already seen a successful launch of their TinyDuino processor board which is essentially a full blown Arduino shrunk down to the size of a quarter.

The TinyDuino processor board uses the same processor as the Arduino Uno (an Atmel Atmega328P) and now includes an onboard Lithium battery charger and battery connector.  All of the normal shield signals are supported, so all of your existing Arduino sketches will run without any changes.

TinyCircuits have written an Arduino library from scratch for the TinyScreen that is optimized for speed and performance but still easy to use.  A Full screen update takes less than 30 milliseconds, allowing for smooth moving videos and graphics. The library includes high level functions for dealing with fonts and text, menus, graphics, gauges and basic shape.  Just a couple of lines of code are needed in most cases to start displaying what you want on your TinyScreen.  The library is completely open source.

They have teamed up with Codebender to make programming the TinyScreen projects simple.  All of the latest libraries, examples, and standalone apps will be available on Codebender, This means you don't have to worry about getting your system set up just right with the specific libraries installed - all of this is handled on the Codebender site so you can focus on creating your TinyScreen project.

Key TinyScreen specs:

  • 96x64 OLED display, 16-bit color depth
  • 0.96" (24.4mm) viewable area
  • Total Size: 1.02" x 0.98" (25.8mm x 25.0mm)
  • Software controllable backlight (OLED brightness)
  • Power down mode
  • Four push buttons along the sides (connected to IO pins)
  • SPI interface for display
  • 3.0V to 5.5V operation (higher voltages supported with TinyShield power regulator)
  • 20 - 45mA max supply current (depending on brightness)
