Description

This mount/holder for the Heltec V4 LoRa radio is probably a little overkill with the following features:

  • a strain relief for antenna pigtails to help prevent the IPEX connector from accidentally disconnecting
  • the IPEX connector is visible/open so you can always see if it's tight or loose, or gives you easy access to hot glue it in place
  • labels for each of the two built-in buttons
  • indicators for the battery and solar ports, including the polarity of the connectors
  • two parts that press fit together to ensure the board is securely held in place
  • multiple mount options, use screws, zip ties, and/or glue

 

Notes:

  • there are two options for the battery and solar port indicators, raised or sunken text to suit your preference
  • Heltec V3 has not been tested
  • designed entirely in FreeCAD

     

Boost MeBoosts are always appreciated and allow me to buy more filament for designing and testing models! - Thank you!
