SS Stepper Controller v1.1 — 5-Axis Board Map →
The clean board: five driver axes (yaw became a stepper), four SN74AHCT125N buffers, eleven 1k pull-downs, decoupling, eleven test points, and an ESP32 footprint measured at a real 25.4 mm so the module finally seats. J11 deleted. Connector map, GPIO assignment, assembly order, and the three-method verification run before ordering.
