Wireless modules and simple setup, what is required?

Found this transceiver module on Farnell.

Anyone tell me if it's suitable for this use. I see it has SPI, I2C and UART listed as protocols.

Hmm noticed that one has abuilt in processor.

How about this one

3.3volt operation and logic levels ? Not sure on that one. Does a 16f628 at 3.3v working output at 3.3v logic levels. Sense says it should, although at bottom end of chips working voltage range.

if it's running at 3.3v, then yes, it'll output at 3.3 logic levels, and there's always the alternative of using something like a voltage divider with a 1.8k ohm and 3.3k ohm resistors if you need to convert the voltage from 5v to 3.3v.

Thanks for that.

I've decided to go with the Ciseco hi power transceivers.

I've written some preliminary code based upon Dave Houstons code. I need to add prelim ID followed by string then acknowledgement just in case of power outage.
