ThinkNode M3 Tracker Card Meshtastic with GPS WiFi BLE 868MHz

The ThinkNode M3 by Elecrow is a compact Meshtastic tracker in card format that combines high-precision positioning and LoRa communication in a lightweight housing. Inside, a Nordic nRF52840 main controller and a Semtech LR1110 LoRa transceiver operate with support for the 868MHz band. The integrated GNSS module receives GPS, GLONASS, Galileo, and BeiDou signals and achieves a positioning accuracy of under 1.5 m (CEP50). All antennas for GNSS, LoRa, WiFi, and Bluetooth are designed as internal on-board antennas, enabling a compact design of 64 × 64 × 10 mm. The housing made of PC and ABS plastic achieves protection class IP66, making it dustproof and protected against strong water jets.

Features:

• LoRa communication on 868MHz with Semtech LR1110 transceiver achieves a range of about 5 to 6 kilometers in open areas
• GNSS module with support for GPS, GLONASS, Galileo, and BeiDou enables positioning accuracy under 1.5 m for precise tracking
• IP66 protection class and robust housing made of PC and ABS plastic make the tracker usable even in harsh conditions
• Integrated 760mAh lithium battery allows up to 18 hours of operation with one transmission per minute
• Bluetooth 5.0 allows configuration and control via the official Meshtastic app through smartphone
• Magnetic charging device, SOS function with acoustic and optical alarm, and temperature, humidity, and acceleration sensors expand the functionality

Application examples:

• Person tracking during hikes, mountaineering tours, and expeditions in remote areas
• Emergency and SAR operations, where reliable SOS signal and position data need to be transmitted without cellular network
• Vehicle or asset tracking in logistics and outdoor applications over a Meshtastic network
• Mesh relays in decentralized communities, amateur radio networks, or festival communication
• Localization of machines, boats, or valuables via LoRa, without dependency on cellular network
