This week I worked on further testing of the PCB in simulation. I worked on generating heat maps using the PCB thermal simulation software as part of Fusion 360. Simulating both external temperature sources and measuring the distribution as well as electronics cooling to determine if electrical bodies exceed maximum allowable temperature given natural air convention. This was based on supplied power consumption and thermal loads. The results were helpful to verify there were no hotspots with a surplus of heat anywhere hence complying with safety standards. I also updated our PCB to include a new SD card reader as we swapped our old one with a new one that includes a 3.3V breakout board as a mitigation technique we learned from the PS/2 keyboard. I am still waiting on the SD cards themselves to arrive but in the meantime I got started on looking into writing appropriate codes to these cards and how H2GTestW can be used exactly. I understood we can use it to generate tests for speed of writing to and reading from our SD card which will be helpful when integrating it with our PCB. Finally, I continued working on tracing the final PCB out with this design alongside Nancy.
