The mysterious RFMB12-D 433Mhz tranceiver
While researching the Raspi Wireless Shield / WiCobber shield, I funnily enough found out a lot more about it when I did a search for one of the radio module it supports.
This is the RFMB12-D.
I don't know what to make of it.
It has 10 pins (5x2), but the Raspberry Wireless Shield details imply it will still work with just 8 connected. It seems the D version is the one with the 5x2 pins attached.
It's quite elusive. There are a number of them sold on Aliexpress, but not all of them have the 5x2 pin configuration. Glimpses can be found here:
It's plugged into another relay board here.
There's also a Frankenstein version here:
It's called the Hope RF12 in the description here, but it looks different:
Does anyone know what this is?
- Is it some kind of RFM69?
- Could it be a 433mhz drop in replacement of the NRF24? A man can dream..
Ah, the RFM12B is a precursor to the RFM69. This video claims it's compatible to a degree. Could it be compatible with MySensors?
- no encryption
- no 'packet handling'.

Not sure about the RFMB12-D, but the RFM12B is an older version of the RFM69. I suspect the RFM69 in 433Mhz would be better in most applications. See Felix's transceiver discussion here:
The RFM69 is definitely better. But I haven't found a commercial version of the RFM69 that can fit in the NRF24 socket (and ideally allow for 5v communication).
If the Moteino allows for the RFMB12 to be soldered on.. does that mean MySensors could also in theory communicate via an RFMB12? Or would modifications to the code need to be made?
// hmm, that page says the RFM12B is not really developed for moteino anymore.
