Selecting your LoRa IC for your application
summary
Compares SX127x (first generation, flexible, supports proprietary modes, ~80 million devices shipped) with SX126x (second generation, half the package size, receive power about half, transmit current down to ~75%), gives concrete figures and tradeoffs, lists evaluation kits, Murata modules, shields for Arduino and Raspberry Pi, and shows that the newer parts provide 150 MHz–1 GHz continuous coverage for worldwide designs and simplified API plus integrated DC‑DC for lower battery drain.
