The BIM2/3G data radio module is a PLL synthesiser based miniature PCB mounting UHF radio transceiver which enable the simple implementation of a wireless data link at up to 128 kbps at distances up to 75 metres in-building and 300 metres open ground.
The BiM3A radio transceiver module is similar in size and pinout to the BiM2, offering all the advantages of the latter but with reduced power consumption and antenna size. The BiM3A replaces the obsolete BiM3.
