KiCad MCP is an Apache-2.0 Python package for a Linux stdio Model Context Protocol server for KiCad project workflows. The MVP is file-first: it inspects KiCad projects, runs sandboxed validation gates, and applies strict transaction-only schematic and PCB mutations without requiring KiCad for default tests.

BedCAN: common questions

What microcontroller does the BedCAN use?

The BedCAN is built around the NE555DR, from the RP2040/RP2350 family.

How big is the BedCAN PCB?

The BedCAN measures 790 × 980 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the BedCAN?

179 components, from 72 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 BedCAN design files?

From the matheusfalcaopinto/kAIcad-MCP 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 BedCAN design in my own project?

Yes, under the terms of its Apache-2.0 license, which matheusfalcaopinto chose for the repository.

Can I test firmware for the BedCAN without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
