Minimalist Europe Card Bus (MECB) - Backplane v1.2 Updates!
HTML-код
- Опубликовано: 28 сен 2024
- This follows on from my earlier Minimalist Europe Card Bus videos.
It was timely to update the first MECB PCB that I'd designed, which was the essential Backplane.
After some good feedback received via the Forum, I decided it was time to apply some useful suggested updates, which moves the Backplane to v1.2
These useful updates resolve a couple of potential gotchas!
Join me as I present and explain the v1.2 Backplane updates, and build & test the first v1.2 Backplane.

Still don't understand the need / want to power projects from power banks / or power bricks.
When working on projects I love the ability to set current limits and voltage limits to my power supply.
if I'm working on 5V projects I set the max voltage to 5.5V then no matter how much I turn the voltage control I can't exceed 5.5V.
This has saved a few projects over the years.
Thanks for making me think about raspberry pi power supplies, I've been looking for a 5V 5A power supply, and just checking CPC for pi power supplies (since the new pi's are power hungry ) and lo and behold a cheaper 5V 5A wall watt for my Spiral lamp 🙂
Yes, I always use my benchtop power supply for development, with it's voltage setting / current limiting capability. But for completed 5V projects, I do really like the USB-C connector format, as a good modern solution to replace the old potentially confusing DC jack. When the Raspberry Pi 4 came out with it's cheap USB-C powwer pack, I was sold! Now with the evolution of Power Delivery, these little connectors are even good for safely powering 9V and 12V powered projects (even up to 28V).
@@DigicoolThings the problem with these USB and even normal wall watts, is the fact that the emissions are tested under full load.
They are design to be very good at full load to pass the tests, not so at lower power levels. The amount of times I've had to add extra ferrites over the output leads to get through CE testing with a wall watt that had passed all it's EMC tests. 😞
@@TheEmbeddedHobbyist Thanks for sharing your experience. I was never involved in product CE testing etc. in my career, but understand what you’re saying. I suppose for hobbyist / maker project use we just need to aware of potential performance variations under different loads.
