From the project
PD1180-EPR — NEMA 34 Smart Motor-Mounted Stepper Controller with USB-C PD 3.1 EPR
Current copper/rule revision: source/native design-rule correction, with 0.15 mm minimum tracks, 0.30 mm GND clearance and 0.50 mm GND edge inset. Existing order/qualification holds remain.
Component names come from native footprint references, including SW1 and SW2; custom imports use {NAME}. Q5, L3, R4, C92, C89 and R9 use inward reference anchors to keep their names inside the board. No names are hidden or replaced with detached captions. Edge labels before · Edge labels after. The earlier pre-label screenshot is preserved byte-for-byte in native-reference history.

Pd1180-epr: common questions
What microcontroller does the Pd1180-epr use?
The Pd1180-epr is built around the STM32G0B1CEU6, from the STM32 family.
How big is the Pd1180-epr PCB?
The Pd1180-epr measures 85.9 × 85.9 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Pd1180-epr?
255 components, from 80 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the Pd1180-epr design files?
From the techmannih/pd1180-epr repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the Pd1180-epr design in my own project?
The repository has no license, so all rights stay with techmannih. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Pd1180-epr without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
