Hello everyone,
This is a follow-up question related to my ESP32-S3 monitoring project.
While investigating the electronics side of the design, I’ve also started reviewing installation and maintenance considerations. The final system will be deployed in locations where power cables, sensors, and communication wiring may occasionally need servicing.
Because of this, I’m evaluating different wire splice types and field-wiring approaches to improve long-term reliability.
Questions:
-
What wire splice methods have proven most reliable in real-world installations?
-
Do you generally prefer crimp splices, soldered splices, heat-shrink butt splices, or lever-style connectors?
-
Have you experienced failures due to vibration, moisture, or thermal cycling?
-
What splice methods provide the best balance between reliability and serviceability?
Mechanical Enclosure Question:
The final product will be housed inside a custom enclosure with cable entry points, connector access, and maintenance provisions.
I’m currently evaluating CNC-machined and rapid-prototyped enclosure options through Justway.
For those who have deployed ESP32-based products:
-
What enclosure-related mistakes caused the most trouble during early revisions?
-
How much additional space do you reserve for cable routing and future maintenance?
-
Have thermal issues appeared after moving from bench testing into enclosed systems?
-
Any recommendations regarding mounting, accessibility, or long-term durability?
I’d appreciate hearing from anyone who has taken ESP32 projects beyond the prototype stage and into real-world deployments.
