Pre-loaded with Meshtastic firmware, it enables secure, decentralised communication without any internet or cellular infrastructure — ideal for outdoor adventures, emergency preparedness, remote area operations, and community mesh networks.Key Features\nReliable LoRa Communication: Built around the Nordic nRF52840 processor and Semtech SX1262 LoRa transceiver, the M1 delivers stable long-range transmission at 915MHz (AU/US frequency) with up to +22dBm transmit power. An external RP-SMA antenna connection ensures optimal signal performance.\n1.54\" E-Paper Display: The always-on EPD screen provides clear, sunlight-readable status information including node details, messages, and GPS coordinates — all with minimal power draw. The 200×200 resolution monochrome display refreshes in approximately 2 seconds.\nHigh-Precision GPS Navigation: The built-in multi-constellation GPS module supports GPS, GLONASS, BeiDou, and QZSS for accurate positioning in any environment. Share your location with other mesh nodes or use it for fleet tracking and navigation.\nExtended Battery Life: A built-in 1200mAh rechargeable lithium battery delivers over 48 hours of continuous use. Low-power standby consumption is just 5.6μA, while maximum operating current (CPU + LoRa) is approximately 85mA.\nBluetooth 5 Connectivity: Configure and manage the M1 wirelessly via BLE 5 using the official Meshtastic app on your smartphone. Send messages, share maps and locations, monitor network status, and customise device settings — all from your phone.\nRTC Clock: The built-in real-time clock maintains accurate time even when powered off, enabling faster hot-start of the GPS and supporting interrupt/wake-up functionality.\nMultiple Firmware Support: Ships with Meshtastic firmware pre-installed. Also compatible with MeshCore firmware for alternative mesh networking optimised for long-distance and low-power scenarios.Specifications\n\nProcessor: Nordic nRF52840 — 32-bit ARM Cortex-M4 @ 64MHz with FPU\n\nMemory: 256KB RAM, 3MB Flash (inc. external 2MB chip)\n\nDisplay: 1.54\" EPD (E-Paper), 200×200 resolution, SSD1681 driver\n\nLoRa: SX1262, 915MHz (AU/US), +22dBm TX power, external RP-SMA antenna\n\nGPS: GPS, GLONASS, BeiDou, QZSS\n\nBluetooth: BLE 5\n\nBattery: 1200mAh rechargeable lithium\n\nInterfaces: USB-C, RP-SMA antenna connector\n\nButtons: Knob switch, function button, page turn, GPS switch, reset\n\nLED Indicators: Power, GPS/LoRa status\n\nPower Input: 5V/1A via USB-C or battery\n\nOperating Temp: -10°C to 50°C\n\nDimensions: 82 × 51.6 × 26.3mm\n\nWeight: 81g (with case)\n\nShell: ABS plastic, integrated closed design\nIdeal For\nOutdoor hiking, camping and adventure communication\nEmergency and disaster preparedness\nRural and remote area mesh networking\nCommunity off-grid communication networks\nFleet and asset tracking\nMaker and IoT experimentation\nWhat's in the Box\n1× ThinkNode M1 Device\n1× USB-A to USB-C Cable\n1× LoRa Rubber Stick Antenna (915MHz)\n1× User Manual\nResources\nUser Manual (PDF)\nDatasheet (PDF)\nWiki / Getting Started Guide\nAlso available: Other ThinkNode models including the ESP32-S3 based ThinkNode M5 and compact ThinkNode M2.]]>","vendor":"Elecrow","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":12,"title":"Default Title","sku":"EC-CIL12901M-1","mpn":"CIL12901M-1","price":78.0,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":148,"option1":"Default Title"}]}
