A real ultra-low power Sigfox development board based on the popular Atmel AVR ATMega328p - Arduino compatible. Thanks to a high-efficient Step-up Switching regulator, this board can be powered with little as 1.0V. In other words, you can run it on a single Alkaline Cell until the battery is totally dry.

Alternatively you could connect a 5V power supply, like an USB charger, and take advantage of the ultra-low quiescent current LDO regulator, providing more flexibility while developing or running hunger projects. The board also counts with a smart voltage monitor, which will automatically switch from a power supply to the battery in case of power-loss or vice-versa. Alternatively you could use a Li-Po cell and the board will decide to use the LDO or the Step-up regulator based on the cell voltage to maximize the running time on a single charge.

As standard, this board comes with a Sigfox Module, giving you long-range wireless connectivity out of the box! 

Finally a W25X40CL 4MBit SPI Flash is attached to the PCB, giving you plenty of storage and option for remote firmware upgrade over-the-air. You get all this running on a board that consumes around 6µA in sleep mode when powered by a 3V source, like two Alkaline cells.

The Whisper Node board is shipped with all headers (un-soldered) and external 1.5dBi (± 0.7 dBi) PCB antenna with a u.FL connector, matching the radio frequency. The small PCB antenna provides an excellent balance between performance and size.

Additionally the board can be easily upgraded to fit a SMA antenna connector, a temperature compensated real-time clock or a high-capacity LDO, making the board a ideal as a low-power remote node.
