LoRa Module 915MHz 100mW sx1276 chip long range 4Km RF Wireless LoRa1276

This LoRa radio module operating at 915 MHz is built around the Semtech SX1276 transceiver. It delivers long-range communication with high sensitivity (down to -139 dBm in LoRa mode) and a maximum output power of 20 dBm (100 mW), enabling reliable links over several kilometers depending on environmental conditions.

Perfect for IoT projects, home automation, or wireless sensor networks, this module supports LoRa™, FSK, GFSK, and OOK modulations. It connects easily to a microcontroller via an SPI interface and features very low power consumption, with a sleep current of less than 200 nA.
