Stabilizer Test Pad - pabile/Pabile-Keyboards GitHub Wiki

The Stabilizer Test Pad (STP), also referred to as Only Stabs, is a dedicated platform for testing PCB-mounted MX stabilizers.

It is designed to verify stabilizer fit, alignment, and smoothness before final keyboard assembly. The STP can also function as a macro pad when paired with a controller that uses a Pro Micro–compatible footprint, and it supports common keyboard firmware such as QMK and VIAL.
