ThinkNode M1 Meshtastic with GPS and ePaper Display

With the ThinkNode M1, you take your mesh communication to the next level. This compact transceiver module is ideal for outdoor adventures, emergency communication, or projects where independent, network-free communication is crucial. Equipped with the powerful nRF52840 chip, it combines Bluetooth connectivity with LoRa capability and is perfect for use with Meshtastic. The 1.54-inch ePaper display offers you an energy-efficient and easily readable interface – even in sunlight. Additionally, the ThinkNode M1 has an integrated GPS module that enables precise location tracking in the mesh network. The operation is simple using the convenient navigation joystick that lets you scroll through menus and control functions. The robust casing reliably protects the technology from environmental influences and is pleasantly compact. Thanks to the open firmware, the device can be individually customized and expanded. A USB-C interface ensures fast charging and easy data transfer. Power is supplied by an integrated LiPo battery that can be conveniently recharged. The side status LEDs provide direct feedback on the operating status and connection. For all tinkerers, makers, and adventurers, the ThinkNode M1 offers a powerful yet flexible platform for modern mesh communication. The easy integration into existing Meshtastic networks makes it the ideal addition to your system. Due to its compact design, you can easily attach it to clothing, backpacks, or drones.
