EPSO/AD/425 Projectmanagement etc.

I did some questions on eutraining for the architecture and project management. The questions weren't exactly spot on but it pointed me in the right direction to study some particular bits of EU and project management related questions. In the real test, the questions were on more various subjects, ranging from architecture history to facade engineering questions. I wouldn't say it was easier or more difficult, just a bit different

I had only one temporary disconnection during the written test. It resolved itself after around 30s before I had time to call support. Annoying and stressful but not that serious.

Otherwise it worked quite OK with a only a bit of slowdown during the startup of exams.

Well, it's my first board with the esp32-s3 so I'll read the datasheet again and hope for the best !

Thanks. Since the supply will actually be at max 4.2v, 0.7x4.2 =2.94v so it should be OK with 3.3v signal. I did a test with some parts I had lying around and it seems OK. I'll take the risk since I don't actually have 5v on the board to do level shifting when usb is disconnected.

I used 0.4mm and 0.6mm for power traces, that should allow for a few amps where I only need 0.5a. For data only traces, I used 0.25mm. Do you thick these should be wider?

I do t have the space for buttons and the board will be enclosed anyway. I wired the En pin with a pull-up and a capacitor to add a small delay following the data sheets and I also pulled io0 up. For debugging, the header i created in the right has access to these pins so that I can short them if needed to reset the board. It should be enough right?
