This week, we finally received our PCB boards, while trying to test the PCB, we discovered that the NMOS that connects to the screen was flipped in the incorrect direction. This could lead to delays in on-screen graphics testing and will require an alternate layout for the screen while waiting for the new PCB. In the meantime, we will resolder the screen connection to the 3V pin or create a breadboard circuit to have the correct NMOS configuration.
There were no significant changes made to the design since the last report. However, due to the long PCB assembly and delivery time, we are considering using local vendors to obtain our PCBs. Using a local vendor could dramatically increase the associated cost due to the convenience of the service, as well as possibly requiring us to assemble the board ourselves. With these factors in mind, we are still leaning towards using our previous vendor due to the additional cost and work associated with a local vendor.
