I'm interested in SX1272 by Semtech. It's a LoRa modem.
I'm not the best at reading datasheets. Maybe it's because of my poor English. I wonder what is the minimum schematic of such a chip? What capacitors, resistors, inductors do I need and where?
On the Semtech's website I found something like this:868 MHz - Combined RFI and RFO (high efficiency PA) design, switchlessThis PDF contains a scheme, but a lot of values of capacitors are not specified. Do I need to somehow calculate them by myself? How to do it?Is it minimal connection needed?
I just want to connect SX1272 to ATmega88.
BTW. As I understand, the SX1272 can not be programmed? - Ie. Upload your own program? But on the other hand, what would be the use of GPIO pins?
