README
README.mdLCD-button-box
A DIY stream deck style button box using a 3.5" LCD, tact switches and an ESP32 Devkit V1.
The button box uses an LCD seated at the bottom of the case. Above that, a PCB is suspended, containing the necessary tact switches. The PCB has square cutout holes to show the LCD image through. To press the buttons, there is a 3d printed stand on each set of 4 switches (one button), holding a clear acrylic square. Through this mechanism, the LCD is visible, and pressing the acylic presses the tact switches, registering a keypress. The bottom right button functions as a change layer button, where pressing that will cycle the button box to a new 'layer', with different icons and key outputs.
The case is made using two parts, a base and a top. The base has 4 'legs' inside it to hold the lcd.
Above that, there is a perimeter ledge for the PCB to sit on.
The top attaches to the base using 4xM3 heatset inserts.
The ESP32 and switches are soldered to the PCB, and headers are soldered in place of the LCD. Jumper wires connect these headers down, underneath the LCD and into the pins on the bottom of the LCD.
The button box connects to devices by bluetooth, but requires a micro usb power source. The button box outputs macros using a combination of CTRL, SHIFT, ALT and F14+ keys to ensure unique macros.

Questions
How big is the LCD button box PCB?
It measures 153.3 × 81.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the LCD button box use?
29 parts. 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 LCD button box KiCad files?
From the Icyconfusion/LCD-button-box repository on GitHub, at the commit this page was made from: the board is PCB/lcd button box.kicad_pcb and its schematic PCB/lcd button box.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the LCD button box design in my own project?
Its repository states no licence, so its author keeps all rights: ask Icyconfusion before reusing the design.
