Wireless low power Arduino

Do It Yourself: Low power wireless platform which is compatible with Arduino.

Wireless Arduino

Warduxere is a project to replace IQRF modules. It is designed to be compatible with Arduino. The base of the HW is the Atmega328 microcontroller and the SI4432 wireless chip.

3D view

Thanks to the kicad software it is possible to make a 3D preview. 3D view of wireless low power arduino:

Requirements

My requirements for the device:

• small&compact
• extra low power - long battery powered
• mesh network
• low bit rate
• truly no license needed
• simple implementation
