LoRa packet radio breakout at 868 or 915 MHz (433 MHz variant also available) with SPI interface and +5 to +20 dBm output. 3–5V input with onboard regulator; range ~2 km; lower data rate than FSK but significantly better sensitivity and range.
3.3V supply only.
Ground reference
SPI MOSI from MCU.
SPI MISO to MCU.
SPI clock.
SPI chip select, also called CS.
Module reset (active low).
Primary interrupt line — TxDone/RxDone flag used by common LoRa libraries.
Optional interrupt — RxTimeout / FHSS.
Optional interrupt — FHSS channel change.
