* You can build it without the microphone. Then you don't need R1, C1 and MK1.
** The ESP32-WROOM Module can be purchased at a lower cost on AliExpress.
Assembly
When ordering from JLCPCB, you have the option to get the front side of the board pre-populated - A service I strongly endorse. Subsequently, you'll only need to solder the ESP32-WROOM module onto the reverse side. With sufficient flux, this task can be accomplished with relative ease.
For those looking to populate the whole board, I suggest using a hot plate or a reflow oven for the front side.
Be careful to keep Isopropyl Alcohol away from the hole of the microphone when cleaning the board!Disclaimer

Questions
How big is the Panel PCB?
It measures 76 × 72 mm and has 2 copper layers, 1.57 mm thick.
What parts does the Panel use?
184 parts, built around the ESP32-WROOM-32E-N4, CH340N, AMS1117-3.3 and CC0603KRX7R9BB104. 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 Panel KiCad files?
From the NandXor96/USBWLEDC repository on GitHub, at the commit this page was made from: the board is kicad/panel/panel.kicad_pcb and its schematic kicad/usbwledc.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Panel design in my own project?
Its repository states no licence, so its author keeps all rights: ask NandXor96 before reusing the design.
