New extra small OEM radio modules for Low Power Wireless

Extra small and cost-effective: dresden elektronik introduces new generation of modules in the US


Soon available in the US, the new OEM radio module is not even half the size of dresden elektronik’s current modules and offers even more options in the design-in process. Last year the Germany based wireless solutions specialist introduced the first prototypes in Europe. For the US market the module deRFmega128-22M00 is being certified and expected to be available by spring this year.


With the new tiny radio module dresden elektronik offers a versatile and pin compatible module with AVR processor for the 2.4 GHz band which features minimal space requirements and current consumption at once. The newly added LGA pad option furthermore facilitates a substantially more flexible integration into customized products.


At 23.7 mm x 13.2 mm the deRFmega128-22M00 is currently the smallest module and has the lowest power consumption of all dresden elektronik modules available in the US. For this reason it is especially well-suited for battery-operated end devices in wireless sensor networks. The radio module is available as an SMT module with the single-chip 8-bit AVR microcontroller ATmega128RFA1 from Atmel. This version is designed for the 2.4 GHz ISM band with an integrated chip ceramic antenna[Walter, K1] .


All dresden elektronik 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 new module can be run with a corresponding adapter board on existing development platforms from dresden elektronik.

Available in Europe are also versions with RF pads and power amplifier as well as the new deRFsam3 module family with Atmels 32-bit Cortex-M3 ATSAM3S4 processor. 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.
