## Description

The BigTreeTech MicroProbe V2.0 is an automatic bed leveling probe designed as a compact, reliable alternative to the CR Touch for 3D printer bed compensation. It is compatible with a wide range of printer platforms including the Creality Ender-3, BIQU B1, and printers using the BIQU H2 series extruders.

The probe uses a servo-actuated pin mechanism to reliably detect the bed surface and provides accurate Z-offset measurements for mesh bed leveling. The V2.0 revision improves on the original with enhanced reliability and a refined mechanical design. Multiple bracket variants are available for popular toolheads including Voron Stealthburner, EVA, EVA 3, and the BTT Terminator.

Firmware configuration files for Klipper and Marlin are included in the GitHub repository. The open-source hardware and firmware files allow customization for bespoke printer builds or integration with non-standard toolheads.
