Overview
The Elecrow ThinkNode M1 is a compact, integrated Meshtastic transceiver designed for off-grid mesh communication. Built around the Nordic nRF52840 ARM Cortex-M4F MCU and Semtech SX1262 LoRa radio, it delivers reliable long-range mesh networking at 868MHz or 915MHz with up to +22dBm transmit power. The device comes pre-loaded with Meshtastic firmware and is fully compatible with the official Meshtastic mobile app for configuration, messaging, map/location sharing, and network monitoring.
The ThinkNode M1 features a 1.54-inch e-paper display (200x200, SSD1681 driver) for ultra-low-power status readouts, a Quectel L76K multi-constellation GNSS receiver supporting GPS, GLONASS, BeiDou, and QZSS, and a built-in 1200mAh rechargeable lithium battery providing over 48 hours of continuous operation. With a standby current of just 5.6uA, the device is optimized for extended field deployments.
The integrated design includes a buzzer, RTC with battery backup, multiple control buttons (knob, function, toggle, GPS, and reset), and LED indicators for power, GPS, and LoRa status. It connects via USB-C for charging and firmware updates, and supports BLE 5.0 for phone pairing. The device ships with a durable ABS+PC protective case and an RP-SMA LoRa antenna, making it ready for immediate deployment in hiking, emergency response, and remote area communication scenarios.
