Makers, hobbyists and developers looking for a low powered Arduino compatible development board with built-in RF capable of running AVR projects for years using just a single AA battery.
Maybe interested in Whisper Node and new board that has been created by Talk² and this week launched over via the Kickstarter crowdfunding website looking to raise $15,000 AUD to go into production.
Watch the promotional video below to learn more about this tiny low powered Arduino development board which is now available to back with prices from just £6, $9 or €8. If you liked this you might also be interested in building an Arduino wind speed meter
A real ultra-low power board based on the popular AVR ATMega328p, the same chip used on the Arduino. Thanks to a highly efficient step-up switching regulator, this board can be powered with little as 0.9V. In another words, you can run it on a single Alkaline Cell, for very long periods, until the battery is totally dry.
If you prefer you can still plug a standard 5V power supply, like an USB charger, and take advantage of the dual 300mA LDO regulator. This give you much more flexibility while developing or running hunger projects and you still can use the battery as a backup.
As standard, this board comes with a RFM69 Sub-GHz RF module, giving you wireless connectivity out of the box! You’ll be able to talk with other Whisper Nodes or compatible boards like Moteino or Anarduino Miniwireless!
