Overview

Crobug direct is an open-source printed circuit board by neggles, from the neggles/crobug repository on GitHub, published under the CC-BY-SA-4.0 licence. It is a 2-layer board of 24 × 12.5 mm with 7 parts on 9 nets, routed with 62 tracks and 14 vias.

Its parts include 3 resistors, 2 capacitors and 2 connectors.

cause you can't get suzyqable anymore

Repository Structure

  • crobug contains a suzy-q-alike adapter with a built in usb hub to give you both CCD and OTG gadget access at the same time
  • crobug-direct foregoes the usb hub in service of being cheaper and easier to assemble, and also triggers BC1.2 mode for 1.5A charging
  • crobug-host is the same as crobug-direct but with a host-mode micro-B connector for booting from a flash drive while using CCD
  • libraries/crobug.pretty contains board-specific footprints
  • libraries/crobug.kicad_sym contains board-specific symbols
  • libraries/shapes3D contains board-specific STEP models (and a few extra)

Building

building most likely does not work at the moment.

(I need to update kikit stuff to deal with KiCad 6 and also actually specify board dimensions, panel tabs etc still.)

Simply call make in the top-top level directory. The build directory will then contain:

  • the main board and top board
  • A panelized version of said boards
  • zipped gerbers for the boards you can directly use for manufacturing

Credit where it's due:

Makefile uses Jan Mrázek's KiKit, which I cannot recommend enough and will need to be available before running make

Jan's jlcparts app was also extremely useful in narrowing down part choices based on what JLCPCB have available.

Questions

How big is the Crobug direct PCB?

It measures 24 × 12.5 mm and has 2 copper layers, 0.8 mm thick.

What parts does the Crobug direct use?

7 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the Crobug direct KiCad files?

From the neggles/crobug repository on GitHub, at the commit this page was made from: the board is crobug-direct/crobug-direct.kicad_pcb and its schematic crobug-direct/crobug-direct.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Crobug direct design in my own project?

Its repository publishes it under the CC-BY-SA-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
