Radio modules deRFarm7

1. Overview

The compact designed radio modules contains a powerful ARM™7 microcontroller with 512
kBytes High-Speed Flash, On-chip USB 2.0 Full Speed Transceiver, Ethernet MAC 10/100
base-T in RMII-Mode and an onboard transceiver for 2.4 GHz or 868/915 MHz.

The 46 pin interface gives access to most hardware functions of the microcontroller.

A long radio transmission range can be achieved by using the coaxial jack (U.FL) version
with an external antenna attached. In the Sub-GHz band several hundred meters (100 m =
330 feet) can be reached without problems. The 2.4 GHz version is able to cover up to
200 m (650 feet) with a ceramic chip antenna. All versions have a 128-bit AES encryption
unit installed.

The 512 kB Flash and 128 kB RAM of the deRFarm7 modules provide enough resources to
be used for any tasks within a wireless sensor network.

2. Application

The main applications for the deRFarm7 radio modules are:

• 2.4GHz IEEE 802.15.4

• 868MHz / 915MHz IEEE 802.15.4

• ZigBee® Pro

• ZigBee® RF4CE

• ZigBee® IP

• 6LoWPAN

• Wireless Sensor Networks (WSN)

• industrial and home controlling and monitoring

• Gateway applications between IEEE 802.15.4 and other networks, e.g. Ethernet
