PCB Design - IoT Project
Budget: $250 – $750 AUD
The project is to consolidate a proof-of-concept equipment-control board, built using various off the shelf components, into a single coordinated Printed Circuit Board (PCB). The board will have incoming and outgoing power terminals for; 240Vac, 24Vdc, 12Vdc and 5Vdc. There will be a 240Vac, “Power” section for all 240Vac terminals and a low voltage 5-24Vdc “Controls” section. All PCB route traces need to be sized accordingly, to accommodate the correct voltage and current going through them.
During the initial prototyping stages, it was found that some parts, particularly input devices, suffered from EMF issues. To reduce the effects of EMF caused, a large “ground” area should be designed into the board to reduce/remove residual EMF. A further study on how to determine the sources of EMF and how best to eliminate them should be done to successfully produce a “commercial” ready PCB.
The PCB schematics are to be used as a guide on the final design of the PCB. Any design issues should be raised, solutions proposed and implemented.
The final PCB design that is required to be completed must be able to be printed and assembled by any PCB supplier. We prefer PCBWay as we have used them in the past, your recommendation will be considered. Some parts are currently in shortage, and the specifications are provided for a suitable equivalent to be used. The final PCB design should consist of parts that can be obtained, to test the full functionality of the board.
Project Deliverables
1. Review PCB concept sketch and schematic to determine the feasibility as a final product.
2. Verify correct resistors and capacitors are used in the debouncing circuit diagrams and voltage divider diagrams.
3. Create a BOM with products that are available to purchase, list dimensions, supplier, and product details.
4. Create electronics schematic using a PCB design software. Exported file must be accepted by PCB manufacturers such as PCBWay. (Gerber type file).
5. Create a 3D model of the final PCB design. Acceptable file types are dxf, dwg, 3ds, stl, step.
6. Investigate EMF issues on the board, propose alternate design solutions to reduce/remove EMF interference with input devices.
7. Assist with placing order on a PCB printing and assemble website (small order).
