ESP32 WLED Level Shifter

A simple board to house an ESP32 dev board and a level shifter, so it can be hooked up directly to a powered 5V LED strip.

This fits a "ESP-32S Development Board", which can be found by plenty of sellers.

Designed for APA102 LEDs, so it has a CLK and DATA output.

Comes with a KiCad (6) board design and 3D-printable enclosure designed in FreeCAD.

See Releases for exported PCB manufacturing files and STL files to 3D print.

Bottom section of the 3D printed box Screenshot of FreeCAD showing the bottom of an enclosure. It's rectangular, has support for the circuit board to lay on, and a clearing in the front left wall for the connector. On both long sides, there are tabs with holes in them to fix the box to something with screws.

Assembled, in real life. Photo of the assembled box. A black 3D printed box with the top and bottom put together (press-fit) is shown. In the clearing for the connector, you guessed it, there's the connector, flush with the edge of the enclosure.

Questions

How big is the Esp32-wled level shifter PCB?

It measures 30 × 59.9 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Esp32-wled level shifter use?

70 parts, built around the CD40106. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the Esp32-wled level shifter KiCad files?

From the michd/esp32-wled-level-shifter repository on GitHub, at the commit this page was made from: the board is esp32-wled-level-shifter.kicad_pcb and its schematic esp32-wled-level-shifter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Esp32-wled level shifter design in my own project?

Its repository states no licence, so its author keeps all rights: ask michd before reusing the design.
