>>Simple case for LilyGo LoRa32 V2.1 RNode

This build uses the LilyGO LoRa V2.1 to make a complete battery powered RNode using a simple 3D printed case that fits together with no screws required.

The case, made by antirez on Printables is a simple snap fit enclosure that is printed in two pieces.

For best quality and strength of your print, PLA+ or PETG is recommended. PLA+ is the easiest to work with on most consumer printers and provides moderate temperature resistance and strength.

The case fits several types of 3.7 LiPo batteries. The one I used is a 1100 mAh 3.7v battery from brand MakerFocus. The batteries dimensions are 50 mm × 30 mm × 7 mm.

`!When connecting batteries to any LoRa device, always check that the polarity on the Micro JST connector matches that on the board`!. If they are mismatched, you can reverse the polarity on the socket of the MicroJST connector to match that of your board by simply swapping the wires (YouTube video).

>>Tips

>>>Finding cases for your LoRa board

You can find cases to print for LoRa devices on sites like Printables, Thingiverse and Yeggi.

>>>Finding antennas

DigiKey is an electronics distributor that has a section for RF antennas that you can use with LoRa. You can filter antennas by frequency and most products listed will provide you with a datasheet that shows the SWR range.
