LoRa1262-915 www.nicerf.com 1. Overview 2. The LoRa1262 wireless module uses Semtech's SX1262 device, which uses a high-precision TCXO crystal oscillator, ultra-low receive current and sleep current, and sensitivity of -148dBm. Built-in 64KHz crystal oscillator can wake up the microcontroller periodically under low power consumption. The module antenna switch is integrated and controlled by the chip, which saves the resources of the external MCU 3. Features Frequency Range:902.8-927.
