  Instructions for your LoRa Solar Station:

Print:

Need at least a buildplate of 180mm. This box has 175mm.

With supports only touching the buildplate. Supports only necessary on the screws and nuts.

Print with HIGH infill density on a filament that can take the rain and heat. Example: PETG, ASA, etc etc.

Back to the buildplate on the box.

Front to the buildplate on the cover.

Has space for 4x, 3x, 2x, 1x 18650 batteries.

This case was designed with the following components in mind:

4mm silicone gasket: https://www.amazon.es/-/pt/dp/B0CWND3XN7

5x - M6 x 30mm screws (and nuts).

PG7 cable connector: https://www.amazon.es/-/pt/dp/B07JH2LPZF

Antenna of this type: (433): https://pt.aliexpress.com/item/1005007301219597.html

(868 or 915): https://pt.aliexpress.com/item/1005007301116616.html

Might help to have an extra gasket for the female connector/antenna and the interior solar panel screw: https://www.amazon.es/-/pt/dp/B09KGPLVJ7

Dimensions and specs:

175mm x 149mm x 60mm

Weight: Around 500grs.

Solar panel tilt: 66º (optimized for the winter sunlight in Lisbon, Portugal ~38.7°N)

Box has thick walls to withstand the weather.

Has two vents to help with heat and condensation.

A series of ideas to stop the rain: silicone gasket, outer wall, screws all outside (except one for the solar panel).

It's plastic so don't go crazy torquing when holding it to the pole.

Example setup for LifePO4 (DOUBLE CHECK EVERYTHING)
