A total of six radio frequency boards included in the kit, two boards per radio transceiver:
-
AT86RF230: First generation 2.4GHz ISM band radio transceiver from Atmel.
-
AT86RF231: Second generation 2.4GHz ISM band radio transceiver with front ends for antenna diversity and external power amplifier and encryption accelerators.
-
AT86 RF212: 868/915MHz ISM band long range radio transceiver with front end for external power amplifier and encryption accelerators.
The radio transceiver share the same printed circuit board with slightly different component values mounted for each of them. See Figure 1 for full schematics of the radio frequency board.
