PCB Review: STM32 Breakout Board with odd configuration

[tooki]

Routing power to the pins connectors is also common. If you have any secondary IC's they will also need to be powered.

In this case, I assume that everything other than the UART ports for daisy-chaining are primarily the key scan lines, maybe with a few LEDs. There won’t be any other ICs, other than complete modules via the UART ports, which have power on them.

I thought the goal was to have a semi-universal board, put a bunch of them together to talk over the same cable in a network, and then have each (mostly) do it's own thing.

We now know what the real intended use is:

Its going to be used to connect bunch of switches on a second PCB to act as a USB input device. For now this is just going to be some small ~40% keyboards, but I also plan on trying it with a gamepad. It's only going to be used by me and maybe some friends, and mostly be left on my dekstop.

I also solder big GND loops to all of my (experimental) projects. A bent piece of copper wire (2.5 square mm), bent with a radius of approximately 10mm. It's an instantly recognizable and solid connection for the GND clip of your scope or crocodile clamps of other measuring equipment.

Or buy nice prebent things like these: https://www.digikey.com/en/products/detail/keystone-electronics/1430-3/2746419

With clever use of round jumpers of different sizes, you can make nice “jacks” for oscilloscope probes that contact both the ground and signal.

WHAT??? Are you mad?

Calm your tits, friend! No need for that kind of response.

Paying 56ct for a piece of bent wire, and then waiting for it to arrive for who knows how long? It can take months to save up a shopping list to get into the "free postage" price range. But I admit, it is an option. Low value shunt resistors can also be abused for this.

Nobody is suggesting placing an order just to buy a single one of these. But I think they’re a nice thing to have around. They’re gold plated and made of much harder wire, making them more durable than a loop of ordinary wire. Make a lot of sense for boards one anticipates doing a lot of experimentation with. And it’s just one example of deliberate test points; cheaper ones exist.

And surely you are aware that DigiKey (and Mouser, Farnell, and the other big distributors) have very predicable shipping times? It’s not “who knows how long”, because you know exactly how long it will take. (Before you jump down my throat again: yes, I know that occasionally orders get held up. But it’s a tiny minority. In the last year, during which I’ve placed dozens of orders from the big distributors, I’ve had exactly one get held up. Smaller distributors like Distrelec and Conrad are a bit more unpredictable.)

Guess I made a misjudgement again.
Thought the satire was obvious enough to not mention it explicitly.
