P40 Keyboards
There are two variants of the Pabile 40-Key or P40 keyboards. P40 started with a staggered 4x10 grid also intended to be used with ALPS switches. This is the keyboard that made it to QMK's configurator. This is the version that is shared here.
The second variant is in ortholinear. The most recent version of P40 Ortho support hot swap (north facing) switches and per key RGB backlights. Support for ALPS switches were dropped in this version.

Another release is a hotswap version of staggered P40. This shares pin outs with the most recent release of P40 with SK6812 LEDs, P40v3.

As shown in image below, six pin headers needs to be pushed from its holder as not to hinder with the MX switches. There should be no exposed pins and just enough solder should be applied - else, switches will not seat properly.
Image below shows a battery connected on P40v3c PCB.
Old staggered version may use this. This stacked acrylic casing is designed for later version with hotswap sockets.
This stacked acrylic casing is designed for ortholinear variant with hotswap sockets. M2 bolts and stand offs are required.
This casing can be printed and are compatible with versions 1 to 3 as long as Pro Micros installed are short (does not protrude off the PCB).
