Why RFM69 rather than RFM26?

Added by NeverDie over 3 years ago

RFM26 would seem to have these advantages:
* Higher sensitivity: –126dBm as compared to –120dBm
* Higher datarate (up to 1mbps rather than just 300kbps)
* Lower power consumption: 50na standby instead of 100na.

I don’t see any downsides. What am I missing?

ND,

With chip/module revisions coming every 3-6 months, probably hours in the day to re-write the drivers ! ;-)

Note that the claimed sensitivity is not at the highest data rates. Since noise floors are often in the nineties (-dBm), using the highest sensitivity is not practical in many domestic environments.

Not sure, but allegedly the RadioHead software will drive it.
