How does the quality of them look? What Ali store did you get them from?
Thanks

rather nice.
seem smaller in width than a BP, but aren’t bread board pin spacing.
the overlap outside the pins has been shaved back.
silk screen printing is very neat and is very small.
and it’s a CB not a C8

Cool
Looks like the robot dyn is probably the better of the BP boards.
Which pin is the LED ?

LED is still at PC13.
So far, I have been very happy for all products made by RobotDyn. The prices are nice, quality is high, and designs are well balanced.

I thought some Black Pill’s (non robo dyn) had the LED on another pin.
Its good that the robo dyn version has it on the same pin as the Blue Pill.

The blue LED is on when PC13 is low (0). My guess is that L on top of C14 is for the user LED. In a similar way, the text ON below 5V is for the red power LED.
A curiosity question: do you prefer straight or 90-degree pins for SWD?
The package comes with 90-degree which is good for low profile use cases. The total height without any other added pins is only 7.4 mm. Most of my boards are using the straight pins.

Sorry, I cannot explain why I said that the STM32 MINI (Black Pill) power LED is red. It is GREEN.
