ThinkNode-M4 Power Bank LoRa Device with Meshtastic/LoRa Tracker Function Powered By nRF52840

ThinkNode M4: Balancing communication and power needs

How to Combine Meshtastic Devices with Power Banks? ThinkNode M4 provides the answer!

ThinkNode M4 is a groundbreaking multifunctional power bank that not only continues the portable power support function of traditional power banks, but also innovatively integrates Meshtastic communication module, LoRa long-distance wireless communication technology and high-precision GPS module, providing users with a new decentralized communication and positioning solution.

Note: Only one of the LoRaWAN Tracker or Meshastic Device functions can be enabled at a time.

If you want to change the firmware, you can download the corresponding firmware and burn it.

As a Meshtastic device, it provides users with high-precision, low-power positioning and communication solutions.

It has built-in Semtech's LR1110 (supporting 868-915 MHz frequency band), Nordic's nRF52840 and GPS modules to ensure the performance and reliability of the device. Meshtastic devices support distributed Mesh networks without relying on gateways or the Internet. Devices are nodes to each other and can automatically expand coverage. It supports two-way communication, including real-time text messaging and location sharing, and can meet diverse communication needs, whether it is point-to-point or broadcast communication. Meshtastic is particularly suitable for field operations, disaster emergenc,ies and other network-free environments, providing users with stable and reliable communication guarantees.

As a LoraWAN tracker, it is lightweight and easy to carry, and can achieve seamless positioning indoors and outdoors. Relying on the LoRaWAN network and GPS positioning, it provides users with a reliable asset tracking solution, especially suitable for coverage needs in fixed areas such as cities and farms. This tracker is suitable for various monitoring and tracking applications, ensuring that users can grasp the location information of assets in real time, improving management efficiency and safety.
