It is a solar-powered communication node that integrates XIAO nRF52840 Plus main controller, Wio-SX1262 LoRa module, and XIAO L76K GPS module. The device comes pre-flashed with Meshtastic firmware at the factory. Utilizes a 5W solar panel in combination with 4*18650 batteries with a capacity of 3350mAh each. This setup ensures continuous operation even in the absence of sunlight, effectively solving the problem of outdoor power supply. It is specifically designed for areas without network coverage. With a built-in battery, it supports long-distance communication, precise positioning, and low-power operation. It's suitable for expanding network coverage in outdoor areas. Features a built-in XIAO L76K GPS module, enabling high- real-time positioning. It supports real-time sharing of location information, providing reliable location assurance for outdoor activities. Equipped with a Grove Ecosystem (The list of supported sensors is provided below.), it is convenient to connect various sensors, such as temperature and humidity sensors. This meets diverse monitoring needs and enables easy functional expansion. It is suitable for long-term outdoor use. The communication range between the two devices can reach 8-9KM in open areas. It can seamlessly integrate into the Meshtastic ecosystem and be used as an outdoor node or repeater to easily expand the Mesh network, enhancing network coverage. Plug-and-play: Comes with a standard cable, which can be directly inserted into the pre-drilled hole (standard D-shaped hole) on the Solar Node bracket. Note: To replace the battery, use Button-top 18650 battery.
