I want to use this to receive the 900 MHz signal emitted from our electric meter to track our house's usage. Can either of these boards do that?
You could probably configure the radio to receive 900MHz, but that's only the smallest part of the problem.
The big part is using the same modulation as the radio you want to listen to. There are *lots* of ways to make a radio send a 1 or a 0: Amplitude-Shift Keying (ASK), On/Off Keying (OOK), Frequency-Shift Keying (FSK), Phase-Shift Keying (PSK), Quadrature/Amplitude Modulation (QAM), to say nothing of all the broadband tricks like using 'chirps'.. a burst where the frequency constantly increases or decreases (increasing being one value, decreasing being the other), and so on.
If you don't know the modulation, I'd suggest starting with a Software Defined Radio (SDR) module:

That hands the problem of dealing with modulation off to a program on your computer, and gives you the freedom to play with the options.
