PCB Gerber Files

The Gerber file can be found on GitHub as a Release:

NOTE: The latest Gerber, and thus the design, includes a JLCJLCJLCJLC silkscreen label. This is used by me when ordering from JLCPCB (no endorsement nor recommendation, just what I use). If you are to use a different manufacturer, I recommend you change or remove this label in the KiCAD file or Gerber file directly.

Step-By-Step Instruction:

If you prefer a step-by-step instruction rather than a single drawing, then click on the link below to go to a step-by-step guide.

Currently only the main driver board has these instructions:

Errata:

Main board Rev 1.0:

• A hardware bug exists where if the CH340C is soldered, due to the CH340 pulling it's pin 2 high nominally, it conflicts when a button is pressed (which drives the pin low). This can be either mitigated by not installing the CH340, or fixed by bending CH340's pin upwards and installing a 1k resistor between the pin and the pad as shown below:

  

• The voltage regulator, for external 7-12v operation, is an LD1117 regulator, which is not pin-compatible with the popular LM7805 regulators or similar
