CEB Press/Manufacturing Instructions/Detroit Fab Lab Solenoid Driver v4

Source File Repository:

All source files are located in this repository: schematics, board layout, netlist, drill list, arduino source code, etc.

https://github.com/dwiel/ose-cebpress-controller-board

Goals

• Add Left/Right/Up/Down buttons on board
• Add Left/Right/Up/Down terminal positions for external control
• Add Left/Right/Up/Down to source code
• Build schematic and board layout in with KiCAD

Design Rational

• Buttons and terminals must all be easy to access
• Circuit board must be easy to etch by hand
• Populating and soldering parts of the circuit board should be easy
  • Using more through hole components this time for this reason
• Circuit board should be small so that they are cheaper and faster to etch/mill

Results

Here is a view of the board with all of the layers visible. You will want to use other views for milling or etching. Other file formats can be found in the repository.

Here is a view of the schematic

In order to build this board, you will need to either:

• purchase an already milled board
• mill your own board
• etch your own board

From there you will need to assemble the board with the following parts:

TODO: refine bill of materials. Materials have slightly changed from previous board.

Notes

• the original MOSFET is rated to 50V,16A but the solenoids listed in the Bill of Materials only use 3A @ 12v (D05S-2C-12D-35 and D05S-2H-12D-35) pdf.
