ThinkNode M4 Meshtastic LoRa Node 868MHz with Powerbank 7000mAh

The ThinkNode M4 by Elecrow is a multifunctional device that combines a power bank, a Meshtastic-enabled LoRa communication module, and a high-precision GPS receiver in one housing. The device is based on a Nordic nRF52840 controller combined with a Semtech LR1110 LoRa transceiver and supports the 868MHz band (EU). The integrated 7000mAh 18650 lithium-ion battery provides 3.65V/25.5Wh and can simultaneously power three devices via Type-C, cable, and wireless charging. An integrated GPS receiver as well as temperature, humidity, and gyro sensors provide additional environmental data, while an LED emergency light with SOS function makes the device usable for emergency situations. The firmware is Meshtastic-compatible and can be configured via the official app using Bluetooth Low Energy 5.4.

Features:

• LoRa communication at 868MHz with Semtech LR1110 transceiver and internal antenna enables reliable mesh communication even in areas without cellular networks
• Power bank function with 7000mAh 18650 battery and fast-charging protocols PD3.1, QC3.0 as well as wireless charging up to 15W supplies multiple devices simultaneously
• GPS module with support for GPS, BeiDou, GLONASS, and QZSS and integrated ceramic antenna enables precise positioning
• Meshtastic-compatible firmware allows configuration and control via the official app via Bluetooth Low Energy 5.4
• Integrated emergency light with three modes including SOS blinking as well as temperature, humidity, and gyro sensors extend the range of functions for outdoor use
• Robust casing made of ABS flame-retardant plastic with PC and TPE and MagSafe-compatible magnetic ring for versatile mounting options

Application examples:

• Hiking, expeditions, and trekking tours in remote areas with mesh communication and team location sharing
• Emergency and rescue operations in regions without cellular networks, where reliable communication and SOS function are needed
• Festivals, events, and camping trips where participants want to communicate decentrally and locate each other
• Setting up a local mesh network between maker communities, amateur radio operators, and citizen science projects
• Mobile power bank replacement for smartphones, smartwatches, and wearables with additional communication and location functionality
