Elecrow ThinkNode M1 LoRa Meshtastic Transceiver is a compact handheld LoRa communication device built around the nRF52840 and SX1262. It is designed for users who want a ready-to-use portable node with GPS, Bluetooth phone configuration, 1.54-inch EPD display, and a built-in battery. This makes it especially suitable for outdoor adventure, emergency communication, community networking, off-grid messaging, event coordination, and field testing. The ThinkNode M1 works well in both the Meshtastic and MeshCore ecosystems. It is shipped as a Meshtastic-ready device, and it is also supported by the MeshCore Web Flasher, where M1, M2, M3, M5, and M6 are listed as supported Elecrow devices. That gives the M1 strong flexibility for users choosing between Meshtastic workflows and MeshCore workflows. Features Based on nRF52840 and SX1262 for low-power portable LoRa communication. Meshtastic-ready out of the box for direct use with the Meshtastic app. Supported by MeshCore Web Flasher, giving it a real MeshCore firmware path as well. Built-in GPS supporting GPS, GLONASS, BeiDou, and QZSS. 1.54-inch monochrome EPD display for real-time status and information. 1200mAh rechargeable battery for extended portable use. Bluetooth Low Energy and Bluetooth 5 for phone-based configuration. Compact enclosed design with RP-SMA antenna, buttons, and USB-C. Very low power consumption with about 5.6uA standby current.

MeshCore handheld node for compact secure mesh communication using the MeshCore firmware path. Outdoor adventure and emergency communication where cellular service is weak or unavailable. Community networking and field coordination with portable LoRa devices. Technology prototyping and testing for Meshtastic and MeshCore workflows. Packing List ThinkNode M1 device x1 USB-A to Type-C cable x1 LoRa antenna x1 User manual x1 Other Content Meshtastic workflowThe ThinkNode M1 is designed to work smoothly with the Meshtastic app for configuration, messaging, location sharing, map features, and network monitoring. If you want to go deeper into settings and deployment logic, you can also read the OpenELAB Meshtastic device configuration guide and the OpenELAB Meshtastic network setup guide. MeshCore workflowThe ThinkNode M1 is also a valid MeshCore device. Since the MeshCore Web Flasher explicitly lists M1 among the supported Elecrow devices, it can also be used in the MeshCore ecosystem. This is important for users who want a portable handheld form factor but prefer MeshCore over Meshtastic. Portable field-oriented designThe built-in battery, GNSS support, e-paper display, and enclosed case make this device much closer to a finished handheld node than a bare LoRa dev board. That is one of the main reasons it works well for mobile field use, quick deployment, and personal carry.
