Project - PWM Motor (Part 4)

Last Modfified: 2021-04-26

Another week, another update! Following up from the previous update, we have some more progress.

Below is the final images for the v0.1 PCB design. The outside PCB trace is now set correctly, meaning the 3D rendering process displays the board correctly. As a result of this, the auto-routing software had a proper boundary to work with and was therefore able to find better solutions to the routing problem.

The board itself has been through several automated validation processes and in theory should work in the most basic sense of the word.

After finally getting this right, we sent the first version of the boards off to be manufactured! We already know that there will be some problems with this board:

On the plus side, there are a few benefits to getting the board manufactured at this stage:

There are probably many other pieces of validation that can be achieved before sending the next batch off.

The boards were sent off soon after the last update and we expect these to arrive soon after this update. We can then begin the task of validating that every part is correctly electrically connected and disconnected as appropriate.

Check back regularly for further updates!
