W9ETC Meshtastic Node
This is a very versatile "universal" enclosure. The PCB Cage in the enclosure accommodates the RAK 19007 Starter Kit, Heltec WiFi LoRa32(V3), Heltec T114, or any other similar board sizes less than 60mm x 35mm x 11mm thick.
Enclosure options include N-type and/or SMA antenna connectors, a waterproof USB-C pass-through connector, and frames/backs to fit 165x165mm, 147x147mm or 145x145mm solar cells. A MPPT controller is incorporated in the electronics design to make solar charging more efficient.
Note: PETG is recommended. Avoid PETG-CF and PLA - both have lower glass transition temperatures which result in warping in the sun.
To avoid maintaining documentation in two places, the complete detailed build instructions are on my GitHub page. The documentation includes:
- Complete parts list & sources
- Circuit diagrams
- Construction photos and instructions
Apr 2025:
- Refreshed model files and added files for multiple solar cell sizes. Electronics enclosure size remains unchanged.
- Added a “empty” electronics enclosure with no insides except what is required for the mount screws for those of you who want to do your own thing.
