I started designing lainboard (name is a work in progress dont hate man plssss :(( ), a compact 3-key macropad with an OLED display and an open section in the case to show the controller and PCB artwork. I kinda want it to have a “raw” aesthetic. There is 100% a better way to describe that which I’m sure I will find in the future.
I set up the KiCad libraries, wired the switches directly to the Seeed XIAO RP2040, and connected the OLED. I then laid out a 90 × 50 mm two-layer PCB, added four mounting holes, routed the connections, and filled the back layer with a ground plane.
For the silkscreen, I converted an image of Lain into a footprint and placed it below the controller. I also added OLED pin labels and replaced the basic header footprint with one showing the display’s dimensions. After fixing the label sizes, the enabled DRC checks passed with no errors, warnings, or unconnected items.
I’ve now started the fully 3D-printed case in FreeCAD, creating the base. Next are the walls, PCB supports, and top plate openings.
