General Description
SX1261 and SX1262 sub-GHz radio transceivers are ideal for long range wireless applications. Both devices are designed for long battery life with just 4. 2 mA of active receive current consumption. The SX1261 can transmit up to +15 dBm and the SX1262 can transmit up to +22 dBm with highly efficient integrated power amplifiers.
These devices support LoRa® modulation for LPWAN use cases and (G)FSK modulation for legacy use cases. The devices are...
