New radio modules in the 2.4 GHz frequency range for use in the ISM band dresden elektronik has three other radio modules of the RCB (radio controller board) series for the 2.4 GHz frequency range on the market brought. Are intended for use in the ISM band, comply with the IEEE 802.15.4, and enable short-range wireless data based on proprietary protocols or through ZigBee / 6LoWPAN / RF4CE / WirelessHART. Two new radio controller boards work on the basis of the radio transceiver AT86RF231 each with SMA connector and have a power amplifier or extended memory (256 KB). These are the boards RCB231LPA V4. 3.2 and RCB231SMA mega256 V4. 4.0. On the third new engine is a 2.4 GHz radio transceiver circuit ATmega128RFA1, the latest single-chip used a solution of 8Bit-AVR-Microcontrollers with integrated radio by Atmel. The single-chip radio module is called RCB128RFA1 V6.
3.1, has a transmission power of + 2.5 dBM and works exclusively with an external antenna. The antenna is connected via an SMA coaxial connector. The Reception sensitivity dBm is-104. Special advantage of these new modules is the fast feasibility of different applications. The 60-pin RCB interface allows a flexible usage with different Peripherieboards and the use of all components of the ATmega128RFA1. Great with a 1kBit serial EEPROM additional disk space available is on the radio controller board. The radio can controller board via two AAA batteries or supplied the 60-pin interface and works in the range of 1.8 V to 3.6 VDC.
The power consumption is approx. 18 mA, in the sleeping state with less than 2 A in the transmit and receive mode. The module a 32 is on low power Timer kHz. Various development boards of dresden electronics allow quick commissioning this radio controller boards.
