$14 Digispark Pro is a Tiny Arduino Ready Board Supporting over 25 Shields (Crowdfunding)

Digispark Pro is yet another small Arduino compatible board, but it costs only $14, and over 25 small form factor shields for Wi-Fi, BLE, mesh networking, etc.. are available for the platform.

Let’s get straight into the hardware specs:

  • MCU – AVR MCU @ 16 Mhz  with 16KB Flash Memory (14.5K+ after bootloader)
  • I/Os
    • 14 I/O pins (2 shared with USB)
    • I2C, true SPI, UART, LIN, and USI
    • ADC on 10 pins
    • 3 PWM Channels (which can be assigned to a selection of pins)
  • USB – Micro USB for debugging, communication and power
  • Misc – One button usable as reset, program, or user button, Power and Test/Status LEDs,  user accessible solder jumpers to disable LEDs, and other features for lower power consumption
  • Power – 5V via micro USB, or External Source – 5v or 6-16v (automatic selection). On-board 500ma 5V regulator
  • Dimensions – 26.7mm x 18.3mm

The board is compatible with Arduino IDE 1.5  for MaC OSX, Windows, and Linux, and comes with fully signed drivers and executables. The USB port supports USB programming, USB device emulation, USB-CDC virtual serial port emulation.

Combined with Wi-Fi, Bleutooth or BLE shields, you can use Digispark Pro as a mobile develoment platform. Example apps with source are available for Android and iPhone, and with Android devices featuring an USB OTG port supporting serial devices, you don’t even need an extra shield and can use the built-in USB serial connectivity in the board. Documentation will eventually show up in their Wiki, and support will be provided via their forum. The boards will be open source hardware released under CC-BY-SA 3.0, and the software will be released under CC-BY-SA 3.0, GPL, LGPL, and/or MIT depending on packages. You can have a quick look at the board and some possible applications from the short promo video below.

Digistrump, the company behind the project, is currently looking for fund on Kickstarter and have already reached their funding target with over $30,000 in pledges at the time of writing. Digispark is not their first crowdfunding venture, and they have managed two other previous successful project on Kickstarter, namely Digispark and DigiX. You could get the board for as low as $10 (Early bird), but these are all gone and the cheapest pledge is now $14 for one board including to the US, with $5 asked for international shipping. You can also add a few extra dollars to your pledge to get one or more of the wireless shields: WiFi Shield for $30, Bluetooth Classic for $15,  Bluetooth Low Energy for $20, and nRF24L01+ (mesh networking) for $7. Delivery is expected for July 2014, except if you select the beta version which will be sent in May.

    is the Tiny Arduino has usb OTG so i can use this usb -otg to transfer both power and data (as slave otg)
    if not which board does?
    or there is an option of host otg or both host and slave otg ?
