Arduino & IQRF SPI demo

Arduino and IQRF title

This demo application describes how to connect the IQRF module to the Arduino. Data are transferred over 4-wire SPI bus, IQRF SPI protocol is used. IQRF module works with 3V logic, Arduino can work with 5V or 3V logic. For 3V to 5V logic connection a level converter is required. This article shows two ways for lever convertor implementation:

The simpliest solution is 3V Arduino ProMini usage. Just connect ProMini with IQRF directly. Following picture shows interconnection between ProMini and IQRF.
