Wireless Arduino

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.

My requirements for the device:

  • small&compact
  • extra low power - long battery powered
  • mesh network
  • low bit rate
  • true no licentious need
  • simple implementation
