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
TODO
- refined bill of materials. Materials have slightly changed from previous board.
Notes
- Does anyone know how much current the solenoids require? We probably don't need such beefy MOSFETs ... (the original MOSFET is rated to 50V,16A)
