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!
Finally each board also counts with a 4MBit SPI Flash attached to it, giving you plenty of storage, including the option for remote firmware upgrade over-the-air.
You get all this running on a board specially designed to consume very little power, perfect for any automation projects, remote sensing or the Internet-of-Things.
