Generic toolhead: common questions

What microcontroller does the Generic toolhead use?

The Generic toolhead is built around the RP2040, from the RP2040/RP2350 family.

How big is the Generic toolhead PCB?

The Generic toolhead measures 42 × 72 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Generic toolhead?

102 components, from 29 distinct parts. The full bill of materials is listed on this page.

Where can I download the Generic toolhead design files?

From the negativeview/generic-toolhead repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Generic toolhead design in my own project?

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

Can I test firmware for the Generic toolhead 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.
