Dresden Elektronik's pluggable compact radio modules deRFmega128-22A00, deRFmega128-22A02, and the solderable radio modules deRFmega128-22C00 and deRFmega128-22C02 include Atmel's Single-Chip ATmega128RFA1, which combines an 8-Bit AVR microcontroller with a 2.4GHz transceiver. The deRFmega128-22A02 and deRFmega128-22C02 offer the same features as the deRFmega128-22A00 except the chip antenna is replaced by a coaxial receptacle (U.FL) for connecting an external antenna.
