Warduxere is project to replace IQRF modules. It is designed to be compatible with arduino. The base of HW is microcontroller Atmega328 and wireless chip SI4432.
3D view of wireless low power arduino:
My requirements for the device:
- extra low power - long battery powered
- mesh network
- low bit rate
- true no licentious need
- simple implementation

Warduxere (old name was Warduino) was awarded the prize in a magazine for the design of electronic journals PE-AR.
For first try is only required:
- USB serial convertor
Connect with USB serial converter:
