This page has some recipes for building complete RNodes based on common LoRa Hardware

Tips

Finding cases for your LoRa board

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

LilyGo LoRa32 V2.1 RNode - Simple case

P1010751-f000252

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
