ThinkNode M6 EU868 IP65 Solar Meshtastic nRF52840 with GPS

The Elecrow ThinkNode M6 is a standalone Meshtastic outdoor node for continuous operation in remote areas, delivered from the factory with Meshtastic firmware and ready to use immediately. The core processor is the Nordic nRF52840 with a 32-bit ARM Cortex-M4 @ 64 MHz; the Semtech SX1262 handles LoRa transmission in the EU-868 MHz band. An integrated 6W monocrystalline solar panel with MPPT charge controller powers two 18650 lithium-ion batteries (7000 mAh total), ensuring weather-independent continuous operation without external power supply.

Recommended Accessories:

• ThinkNode M2 Meshtastic with OLED Display
• ThinkNode M1 Meshtastic with GPS and ePaper Display
• ThinkNode M5 ESP32-S3 Meshtastic with GPS and ePaper Display

Features:

• Factory Meshtastic firmware allows immediate commissioning without programming effort through the official Meshtastic app (iOS/Android)
• Autonomous solar system with 6W MPPT charge controller and 7000 mAh battery ensures continuous operation even during several days of cloudiness
• IP65 protective housing and operating range from -20 to 60 °C allow year-round outdoor use under extreme weather conditions
• Integrated L76K GPS module provides real-time location data for location sharing, asset tracking and emergency communication in the mesh
• Two waterproof SP11 expansion interfaces (I2C + UART) allow direct connection of external sensors to the sealed housing
• Flexible mounting options (wall, mast, pipe clamp, U-bracket) allow attachment to almost any outdoor structure

Application Examples:

• Setup of Meshtastic relay points in mountainous or rural terrain for decentralized, infrastructure-independent communication
• Environmental monitoring in agriculture or forestry with connected temperature, humidity or gas sensors via SP11
• Emergency communication network for search and rescue teams in areas without cellular coverage
• Permanently installed outdoor node for GPS location sharing and position transmission in the Meshtastic network
• Extension of existing Meshtastic communities with a weatherproof, autonomous network node on roofs or masts
