RFM12B End of Life


Whilst investigating use of RFM22B / RFM23B as an alternative to RFM12B, I’ve discovered that all three products are End of Life, I’ve contacted HopeRF to see if there are more details available.

Currently the RFM69W is being suggested as replacement.

Why ? Well the RF chip in use in the HopeRF products the Si4431 from Silicon Labs has been similarly been EOL’d

So is there any evidence of RFM products disappearing from the channel, and the answer would appear to be yes.

See the following screen grab from RS’s website.

So what future for cheap wireless sensors ?
