SOI_Sentinel:
You forgot Aerocomm modules. They look to be roughly equivalent in price and performance to the Maxstream modules, but appear to use the TI/chipcon CC2430. The major difference I see operationally is that they’re surface mount.Still looking for more information… no publicly available technical datasheet right now.
yes- Aerocom’s ZigBee offering. Sorry - they’re stealthy re ZigBee. Their website says they haven’t yet been through certification, but this is simple with the TI/Chipcon base. TI/Chipcon was (is) the first to have a 2nd gen ZigBee chipset with the MAC/PHY radio and the MAC/NWK layer firmware on the same chip’s microprocessor. Aerocom is one of the few with an optional high power module - important in many/most situations.
Their non-high power seems to have way less power than most everyone else- spec sheet says -2dBm including 2dBi of antenna gain = -4dBm Pout. This is less than a 1/2 mWatt whereas most other have at least 1mW.
about half of these modules are surface mount. The Helicomm SDK has this odd (for me) arrangment of spring clips to mate with the module for testing; the module pops-into these clips and sits fairly securely. But these things aren’t socket-able. I guess the idea is that in volume $5ea they’re expendable.
