Designed for LoRa devices, the IBC solar panel brings long-lasting power support Let's say you need to solar power a space-constrained device, such as farm irrigation a mobile communication device or an outdoor sensor. In this case, designing a larger solar panel may be limited by space constraints, as the device itself may have reached its size and weight limits Therefore, choosing a design with 5200mAh and a 5W panel Adopting 3D toughened glass with special heat treatment, the hardness reaches 9H, which strongly protects the screen from scratches and breakage in daily use D5 support is used in conjunction with the Mesh project to enable you to use inexpensive LoRa radios as a platform for remote off-grid communications in areas where there is no existing or reliable communications infrastructure. This project is community driven and open source! Solar Panel Power:5W Antenna:GPS & 868/915MHz Surface Material:Tempered Glass Surface Conversion Rate:24.3% Built-in battery:5200 mAh lithium battery (The product printed words may vary depending on the batch, but this does not affect use) Color: As Shown Material: plastic Specification: 868MHz Package Contents: 1*D5L Solar Repeater LoRa Node kits(The color of the latch is random.) Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
