Very nice! What did you use to produce that?

I think the SWD pins might be mislabeled. Isn't SWCLK PA14 and SWDIO PA13? They are labeled PC in the pdf file.

Very nice. I like this.

How about a webpage where you can search pins by e.g. port name? Simple javascript would highlight corresponding pin in the picture.

To add to that I'd see a use for when you highlight a pin it gives a balloon help with a description of what the pins is used for. This includes the alternate uses. Might as well wish big.

I do love those pinout pictures. I end up printing them out on photo paper for reference.

A while back I had done something like what you both want using google spreadsheets. The one I did was for the LPC1114FN28. Once the page fully loads, you will see some of the boxes have a black triangle in the upper right corner, If you hover over the pin it shows a description for that pin.

Good spot! PDF updated. I used Libre Office Draw by the way.

Cheers

Hi guy's, I replaced the R10 from 10k to 1k5 (0603 is original resistor but 0805 fits ok) but on the schematic I see that R10 goes between D+ (after R11) and 5V but on my board it goes to Vcc3V3 and not to 5V rail ?! ... how many variants of these boards are there?!

I took a short video with microscope of mine (with replaced R10) if anyone care to look ..

The Maple mini pulls D+ to Vcc, not 5V so it should work OK.

We have noticed that some "BluePill" boards have 10k resistors fitted, some have other values, so it looks looks like a "BluePill" is not always the same as the other BluePill boards that people have.

I don't have any BluePill's but I have some of the rare RedPill boards; however your board is different from my RedPill as well, (not just the colour).

It looks like the USB connector is different. It appears to be a micro USB but has 4 fixing points and also they seem to have a cutout in the PCB under the USB socket, so I presume its slightly recessed into the board.
