[OpenTRV-dev] What else do i need

[Damon Hart-Davis]

nRF24L01 at least has reasonable power-supply voltage range (ie for 2xAA rechargables or 3.3V).

Thanks

Damon

There are other modules which, while not as cheap, would still be suitable.  I also haven't ruled out doing my own module based on the newer SiLabs transceiver chip or the TI CC1101.

The mods I have done are to add an RFM23B and to break out the programming pins to an external header.  These are currently just wire-mods, but I am considering whether there is any scope for fitting headers that would plug in to a small custom board, which would make assembly easier.  I'll be writing all this up online soon and publishing the code, but I wanted to make some actual progress first.
