LoRa Long-Range Node — ESP32 SX1276 Radio Link

Description

Send sensor data kilometers, not meters. An SX1276 LoRa module paired solder-free with an ESP32-C3 gives you long-range, low-power links between nodes — tested 12km line-of-sight with the included whip antenna, AES-128 encrypted end to end.

What is in the box

• ESP32-C3 SuperMini development board (pre-flashed)
• SX1276 LoRa module (915MHz) with whip + spring antennas
• 18650 battery shield V3 (node power)
• Jumper wires + USB-C cable
• Step-by-step build guide

Wire over SPI — full pin map in the guide. The pre-flashed firmware talks to a second node or any LoRaWAN gateway, and logs packets to Home Assistant over Wi-Fi when in range.
