T-Solar get it now
Overview
The T-Solar Kit is a solar charging expansion solution designed for outdoor IoT devices. Provides stable off-grid power for low-power devices (environmental sensors, agricultural monitoring stations, field positioning terminals, etc.) via a 5.4 W peak solar panel with a wide input range of 4.4–6 V. Uses a standard JST2.0 interface for quick installation. Includes all mounting screws and hardware (SUS304 stainless steel). Compatible with T3, T-Beam, T-Echo Lite, and other mainstream LILYGO mainboards.
