With the new radio modules in mini format there is  a versatile and pin compatible module family with AVR and Cortex-M3 processors for the 2.4 GHz and sub GHz band which features  minimal space requirements and current consumption at once. They belong to the  smallest radio modules currently on the market.

The radio modules are available as an SMT module either with the single-chip 8-bit AVR microcontroller or the high-performance 32-bit ARM Cortex-M3 microcontroller from Atmel. Whether as an energy-saving end device, router or network coordinator, both series satisfy the requirements of various types of devices. However, the Cortex-M3 modules are even more suited to the more complex tasks of a router or coordinator.

Using module variations with RF pads, the user can create his or her own antenna designs. In addition, control lines for power amplifiers and antenna diversity are available and allow user-specific combinations and expansions. It is not necessary design an antenna when using the version with a ceramic chip antenna, which is just a few millimeters larger.

At 12.2 x 19 mm the deRFmega128-23M10 with RF pads is currently the smallest module and has the lowest power consumption in the new series. For this reason it is especially well-suited for battery-operated devices. In contrast to the Cortex-M3 modules, a version designed for the 2.4 GHz ISM band with an integrated ceramic chip antenna also exists.  
The current developments in the ZigBee market and complex applications in sensor networks could only be partially catered to with the existing deRFmega128 modules. The new radio modules deRFmega256 for the 2.4 GHz frequency band have enough resources available to meet the requirements of ZigBee IP and Smart Energy as well as of the current ZigBee Light Link profile. . Compared to its predecessor ATmega128RFA1, the new AVR-SoC offers double the memory (256 KB Flash, 8 KB EEPROM, 32 KB SRAM).

The Cortex-M3 modules with an integrated USB interface offer higher performance and are pin-compatible with the AVR-based modules. They are available with RF pads for both the 2.4 GHz and sub- GHz bands. The Cortex-M3 modules, with their low power consumption and greater storage capacity, can fulfill the demands of all of the devices in a sensor network. Compared with AVR modules, they are even better-suited as routers and gateways with 256 KB Flash and 48 KB RAM.

The new IEEE 802.15.4 OEM modules are supported by MAC Stack, 6LoWPAN and ZigBee software and have a 128-bit AES unit for data encryption. The modules can be run with a corresponding adapter board on existing development platforms from dresden elektronik.

For the small OEM radio modules we provide you as of late appropriate adapter boards for evaluation. They come with two 23 pin male connectors and are pin and functional compatible to the established eval module series of dresden elektronik.
