LED Pin numbers on generic boards

Can anyone with a Generic STM32F103 board let me know which pin has an LED attached ?

I know the mini maple look alike F103C8 boards appear to have the LED on pin PC13, and its active LOW

On my F103Z board the LED is on PG15

And on my F103V board it appears to be on PB9

I need to know so I can build generic bootloaders for all the relevant boards, so that the LED’s will blink, but there are too many GPIO pins that LEDS could be on, so I can only build for known boards.

Thanks

Roger

And on my “Blue Pill” there is again a (Red) power LED plus a controllable (Blue) LED on PC13

I find the power LEDs rather irritating, since on low power projects they eat batteries unnecessarily, but are usually placed in awkward difficult to unsolder spots on the board.

I suggest in the Generic boards thread we open a new sticky thread that has:
Name of the chip used, picture of that board, link to the bootloader for it.

Good idea

I’ll do it later

Thanks.

Actually after I’d posted, i realised that the c series doesn’t have Pd pins, but didn’t get chance to change my post

I actioned your pull request

Thanks for letting us know what board you have.

Can you post a link in case anyone else wants to buy one, or did you make it yourself ?

Here the schematic:
