• Pre-Assembled All-in-One Finished Device, No Assembly Required: This W12 ultra-long-range LoRa communication device is a fully pre-assembled finished unit that integrates the upgraded main control board, built-in 3000mAh battery, and high-precision GPS module inside a premium protective casing. It eliminates complicated manual welding, wiring and assembly work, greatly reducing deployment and development costs. Designed for out-of-box use, it perfectly fits rapid IoT prototyping, field monitoring, long-term outdoor deployment and commercial project application for both individual makers and enterprise users.
• High-End Chipset & Extended-Range LoRa Transmission Performance: Powered by a 240MHz dual-core ESP32-S3R8 MCU with 8MB PSRAM and 16MB Flash, paired with the 4th-gen LR2021 professional LoRa chip for ultra-fast computing and stable signal processing. It features 30dBm high transmit power and -142dBm ultra-high receiving sensitivity, delivering 20% to 30% longer communication distance compared to high-quality models on the market. It supports 125kbps standard LoRa long-range transmission and up to 2.6Mbps FLRC high-speed data rate, enabling stable and real-time long-distance audio and image data transmission for diverse IoT scenarios.
• Full-Band Multi-Mode Communication & High-Gain Antenna Reception: Supports WiFi 4, BLE 5.0 and LoRa triple-mode wireless communication, covering 150~960MHz Sub-1G and 1.5~2.5GHz 2.4G full frequency bands to meet all mainstream IoT connection requirements. Upgraded from 2dBi to 3dBi high-gain omnidirectional antenna with independent LoRa and 2.4G IPEX antenna interfaces for wider coverage and stronger signal penetration. It supports GPS and Beidou dual-mode positioning, equipped with offline GNSS data caching and automatic data supplementary transmission after reconnection, ensuring stable positioning and communication in complex and weak-signal environments.
• Industrial-Grade Reliability & Efficient Solar Low-Power System: Built with industrial-grade performance, supporting a wide operating temperature range of -40℃ to 85℃ and reinforced ABS case, ensuring stable operation in extreme cold, intense heat and harsh outdoor working conditions. Adopting upgraded CN3791 power management IC, it supports 4.5V~20V solar panel input and 5V/2A Type-C dual charging, compatible with 10W+ solar panels and 3.3~4.4V lithium batteries. Featuring 10μA ultra-low deep sleep current and over 85% solar charging efficiency, it effectively doubles device battery life, with customizable charge and discharge protection thresholds for safer operation.
• User-Friendly Design & Universal Industrial IoT Compatibility: Comes with a 0.96-inch yellow-blue dual-color OLED screen with excellent sunlight readability for real-time viewing of device operating status and data. The integrated USB 2.0 Type-C port supports one-click program flashing, data transmission and fast charging without extra tools. It fully supporting ESP-IDF development, sidewalk, lorawan, w-mbus, wi-sun, z-wave protocols, as well as dual-mode OTA upgrades. Widely applicable to industrial IoT monitoring, smart agriculture, smart city systems, outdoor emergency communication and maker education projects.
