Make prototypes with Sigfox IoT technology and Arduino language. The whole range available at Akeru.cc


If you need a board to prototype earlier, check our shield Akene.


This new version of Akeru offer a better acces to advanced features of the modem and a low power usage.

Many applications have been developed with Akeru like water or electricity meter readings, hives weighing systems, run count or warning pollution. You have to figure your useful or funny use.


Gives you the possibility to use the IoT Sigfox technology as easy as sending data to a serial port with Arduino. Nothing complicated to configure.


Akeru beta 3.3 schematic



Include the librairy :

#include <SoftwareSerial.h>

#include "Akeru.h"


Initialize the modem :



Send data :

akeru.send(&data, sizeof(data));


The data are available into your Actoboard.com dashboard and can be fowarded to any internet address through this plateform.


Librairy available on our GitHub account.


Disclaimer :

The network is being SIGFOX densification in the territory (French mainland). Suitable for outdoor use, coverage inside buildings, like any communication technology, highly dependent on the conformation of places and the environment.

When purchasing, you agree to send us at least one address where you plan to use the board. We will estimate the quality of coverage. If it is good we will send you Akeru board, otherwise, we will contact you to explore other places of use or refund you.

Always connect the antenna before powering the card (otherwise the energy normally dissipated in the antenna will be converted into heat in the modem and can destroy it).


The kit includes :

The Akeru beta 3.3 board with Sigfox TD 1208R modem and a half-wave antenna.

One year of Sigfox connectivity (within the limit of 140 messages per day).

Access to your data on Actoboard.com with specific Akeru plan


Annual Sigfox connectivity fee (within the limit of 140 messages per day) via Akeru next year, 15€ ttc per year.

Actoboard.com fee is available on the website.


By choosing to use Akeru, you agree to stay within the limit of 140 messages per day. Beyond, the data is not saved; on exceeding the number of messages, a more than proportional penalty is applied for example for 10 messages too, we reduce the threshold at 120 messages per day for a week, 20 too, 100 messages per day for two weeks, etc. You will be automatically notified by email as soon as you reach 100 then 120 and finally 140 messages per day.
