Single Gang Waveshare ESP32 Touch 4.3" Mount
- This mount allows for a Waveshare ESP32-S3-Touch-LCD-4.3 to be installed in a single gang wall box.
Warning
This mount and associated components are not certified or designed for installation in a box with AC mains (utility) power.
- A 3.3V DC power source (I recommend a 3.3V 1A Isolated Step-down DC Module)
- PH 2.0 female connector to provide 3.3V to the Waveshare device via the battery connection (see NOTE at the bottom of this README)
- 8mm x 3mm neodymium magnets (x4)
- 3.3 oz of filament (PETG recommended)
- Physical switch (x2 if you intend to program in-place)
- Optional 3.3V relay module to control a device with the physical switch (use with loaded back box)
- Optional I2C SHT41 Temp + Humidity sensor
- 0.20mm layer height
- All componets should be printed with tabs facing up
- Build plate supports are needed only to print the back box and top bezel
- If printing the loaded back box, set the overhang threshold to 50 degrees
- Pause the print when the magnet column walls are finished but before the top chamfer (should be somewhere around layer 40 for the mount and 65 for the bottom bezel)
- Once paused, install the magnets, ensuring correct polarity so the bottom bezel will fasten properly, then resume the print
- The perforated rectangle at the top of the mount facilitates a cutout for programming without disassembly or removing the Waveshare device
- You must install and wire the hidden switch to the positive terminal of your power supply
- Use this switch to de-power your device prior to connecting a USB C programming wire
- The BOOT and RESET switches are accessible via holes in the left side of the mount
- Once assembled, to remove the top bezel, slide a utility knife under the top lip of the bezel and carefully pry to push the case shell outwards
- The physical switch should nicely press-fit in place, but if you want more security, use glue or use the 1.5mm holes to add retaining pins
- There are two versions of the Back Box:
- Empty provides a single open cavity behind the mount
- Loaded creates pockets and snap-fit provisions for a relay module and power supply (use with Back Box - Loaded PCB Standoffs.step)
- There are two versions of the Top Bezel:
Note
The 3.3v battery header connector polarity is reversed from many PH 2.0 connectors. The stenciled polarity on the Waveshare PCB is CORRECT. Use this as your guide.
