  • CPU = MSP430
msp430 would allow an OS like Contiki/TinyOS2 to be used
msp430 sleep mode is OK (but probably more than old rtc technique


  • radio

150 or 173MHz seems essential. Radiometrix make "smarter" radios but they may be too big!

bim1h is high power but same trickyness as old Bim.

TR1m is microcontroller version of BiM - so we could standardise the digital side. Also possible at 150MHz with new antenna needed.

smx1 has microcontroller - worth evaluating? but 53x32mm is big.


in any case a new antenna/full rf design is needed again - with on-ice tests
