Cnc interface panel: common questions

What microcontroller does the Cnc interface panel use?

The Cnc interface panel is built around the STM32F103C8T6, from the STM32 family.

How big is the Cnc interface panel PCB?

The Cnc interface panel measures 80 × 55 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Cnc interface panel?

40 components, from 16 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 Cnc interface panel design files?

From the jamwaffles/CNCMachine 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 Cnc interface panel design in my own project?

The repository has no license, so all rights stay with jamwaffles. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Cnc interface panel 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.
