SeedHammer II hardware

PCB 3D render PCB 3D render

This repository contains the design files for the SeedHammer II machine.

PCB

The schematic and PCB are in KiCad format.

Generate production files (gerber, BOM, CPL) with the Go script:

$ cd pcb
$ PATH=$PATH:/path/to/kicad-cli go run .

Production boards are manufactured by JLCPCB with the following settings:

  • Surface Finish: ENIG
  • Material Type: FR4 TG155
  • Stackup: JLC04161H-7628 (impedance controlled)

LCD

In addition to the PCB, an LCD from buydisplay.com is required. Only the variant with capacitive touch is supported by the firmware.

CAD

The CAD files for the custom machine parts are in STEP format.
