RFM69 breakoutboard, what components to use?

[Cliff Karlsson]

I just ordered this breakoutboard from OSHpark RFM69 Breakout board

But I don't understand what components I need to order to make it work with the RFM69 radio. I am not interested in the SPI flash or sd card reader, but I guess I need some smd resistors atleast.

Looking at the schematics: If you don't want to use the LEDs or the CE pin for future use of the RFM69, I don't think you need to add anything. Maybe a 2x4 female header for the NRF if you want to be able to disconnect it easily.

Edit: Antenna is needed, of course, and the female/male header would be for disconnecting the RFM breakout from the NRF port I mean. Didn't come out correct the first time.

You might want to look at this one which is much simpler (IMO): https://github.com/uChip/RFM69W_BOB - it has space for a 3.3V power regulator and level shifting resistors if you need them.

I made a modified (even simpler) version of that which you can find here: https://oshpark.com/shared_projects/OhoMAYdA which I've used successfully. It requires a 3.3V input but it will do level shifting via resistors or you can solder the jumper pads if you already have 3.3V signals (that's what I did).

Ok, I wanted the board in my post as it used the same pin out as the nrf01. But then I guess that I will not be able to use the breakout board with anything other than mini pro 3.3v as the input are not 5v tolerant

You could combine the two ideas and create a PCB board with level shifters and the 4x2 connector.
