Hi,
Can I replace the hoperf module that came with a moteino with one with a different frequency? Is there any difference in the host MCU? Just remove the old and solder back in the same place the new one?
thanks
(Yes, I know I can study the docs just lazy... :))
Hey stern0m1,
Yes you can replace the radio's on the board with other frequency transceivers. Just make sure you are using the correct board footprint for your radio. Here's a picture of the same board with a couple of different transceivers mounted. Notice how the board is mounted specifily for each radio

This picture references the new R6 boards. If you have the older R4 board then I believe it will allow a different assortment of radios.
And you have to change the sketch also, to freq. you will use

Or, depending on the frequency change, eg 915 to 898, you can just change the code and the radio will work...
433 <-> 915 works too, but with some performance penalty.

For 898 maybe it would still be pretty ok, but normal freq. is 868, which is ways away already and module itself needs different components. From 915 to 433 I don't think it would even work

I meant to say 868, not 898. However, as far as I know, the RFM69 915 MHz module is actually sold as 868/915 MHz. I do know that you can receive on either frequency if you're using a 915 or 433 MHz module (my Sniffer can monitor on either frequency).
However, you may be correct about transmit - I have transmitted on either frequency with a single module, but that was a lab bench setup and I didn't care about range.
