Description
The ThinkNode M6 Outdoor Solar Power is a high-performance Meshtastic IoT device designed for harsh outdoor environments and industrial scenarios.
It features the nRFLR1262 LoRa transceiver module and the nRF52840 core processor, supporting Bluetooth and LoRa dual-mode connectivity to ensure stable signal coverage. Equipped with a 6W solar charger and two 18650 batteries, it offers all-weather operation. Its IP65 waterproof housing allows operation in extreme environments ranging from -20°C to 60°C. It offers flexible mounting options, including wall mounting, brackets, pole mounting, and U-shaped clamps.
ThinkNode M6 comes with dual SP11 waterproof aviation connectors and supports long-range communication, precise positioning, and low-power operation. It can be used out-of-the-box, and rapid deployment, ideal for Meshtastic network expansion, remote monitoring, outdoor emergency response, and off-grid communications, especially in remote areas with limited outdoor network access.
Designed and manufactured by Elecrow, customized requests can be discussed(based on MOQ), you can contact us at service@elecrow.com.
Feature
-
All-Weather Power System
-
- Integrated 6W high-efficiency silicon solar panels and MPPT smart charging maximize energy harvesting efficiency.
- Combined with a large-capacity lithium battery and ultra-low power consumption, it maintains stable operation for extended periods.
-
High-Performance Hardware Configuration

Dual-mode communication chip for wireless connectivity
-
- Bluetooth 5.4 (BLE) enables fast near-field configuration and low-power connectivity. The LoRa SX1262 chip supports the full 150-960 MHz frequency band.
-
Flexible Expansion
-
- Dual SP11 waterproof aviation interfaces support IIC/UART, enabling quick access to various sensors, such as temperature, humidity, gas, and soil sensors etc.
-
Local Data Processing
-
- Edge computing capabilities support local data pre-processing (such as filtering, compression, and protocol conversion), reducing cloud reliance and improving response speed and privacy.
-
Simple Deployment and Compatibility
-
- Pre-installed with Meshtastic firmware and support Meshtastic App, compatible with Meshtastic ad hoc networks, for out-of-the-box use.
-
High-Precision Positioning
-
- The L76K GPS module supports real-time, accurate positioning and location information sharing.
-
IP65 Protection
-
- The integrated sealing structure supports an IP65 protection level and can be used in environments ranging from -20°C to 60°C.
-
Multiple mounting options
-
- Supports wall mounting, bracket mounting, pole mounting, and U-shaped clamp mounting.
-
Multi-scenario application coverage
-
- It can be used in wide-area IoT applications( remote monitoring, environmental monitoring, and asset tracking), and also supports ad hoc networks, making it suitable for distributed deployment in areas without network coverage.
