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.

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 [1].

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.
• Pullup resistor for buttons can be set in code - http://arduino.cc/en/Tutorial/DigitalPins
