Dooba ioNode Microchip AVR Development Board Comes with a C programming SDK

The new Dooba ioNode development board is multifunctional and can be used for projects with space limits. The board features Microchip ATMEGA1284P AVR microcontroller, Dooba’s open-source embedded development ecosystem boasts of a variety of add-on modules which provide the board with increased functionality.

These modules will work perfectly with the board and with any project that supports an SPI interface. Some of these add-on modules are:

  • An Aecho MP3 player
  • Nomad LiPo battery
  • Inpad user input module
  • MicroSD socket in SIP or DIP versions

The development board is available with either male or female headers. It is also shipped with an IOPROTO prototyping board. You can also choose whether you want the headers already soldered on the top, bottom, or not soldered. The ioNode also features a USB port with USB-UART for programming.

On a Final Note

The Dooba ioNode board has a very small footprint, and hence can be used to build applications of any size with ease. The board does not relies on the Arduino IDE, but instead on the Dooba SDK which “allows extremely fast and straightforward development of firmware components, both simple and complex” using C programming which can be installed as follows:

More information on Dooba’s ioNode and SDK can be found on the official documentation page, getting started guide, and Bitbucket.

You can buy the product at Dooba’s online store for just 35 CHF (about $35 US).

Did anyone find out who they are and where they are? There’s no contact info anywhere on their page.


the distance from one row of pins to the other is 0.5″ (I can tell by counting the number of breadboard holes between the rows) . That’s impressive. The DIP-40 through hole package version of the ATMEGA1284P IC alone has a width (distance from one row of pins to the other) of 0.6″.
