Re: F405 & F411 versions of the BluePill

Thanks... I forgot that... Yes, but this means that it was a good idea :-) So we may keep it! Another subject, MicroSD, which is a superior feature of the F405: look at this beauty: http://www.molex.com/molex/products/datasheet.jsp?part=active/1040310811_MEMORY_CARD_SOCKET.xml ...

Re: F405 & F411 versions of the BluePill

Just a thought, but if Boot0 was a button, perhaps we could also run a track to an unused GPIO pin, so in normal operation it doubled as a USER button. (though potentially glitches on the GPIO pin at boot time could cause problems IIRC, this was the option used in the Maple Mini, where the BOOT0 sw...

Re: F405 & F411 versions of the BluePill

Regarding the reset button switch: I used the ultra-small (3.5 mm L x 2.7 mm W x 1.4 mm H) ALPS SKSGACE010 in some of my existing designs: http://www.alps.com/prod/info/E/image/Switch/Tact/SKSG/SKSG_L.GIF 2D drawing and 3D STEP files here: http://www.alps.com/prod/info/E/HTML/Tact/SurfaceMount/SKSG/...

Re: F405 & F411 versions of the BluePill

[edit] - just as a safety check i took most of the chinese characters, the 5P etc. etc. and dropped them into a search: it came up with 2 pages of vendors selling parts that look exactly like this one, which isn't quite enough to be "safe" that they're not all rip-off merchants. however as it's a m...

Re: F405 & F411 versions of the BluePill

A mid-mount micro USB socket like the one used in the Bluepill would be the best, it makes the overall board thinner and it has 4 large TH legs that prevent tearing it apart from PCB when plugging/unplugging the cable. Look at this one, only 0.06 RMB: https://item.taobao.com/item.htm?id=531741597795...

Re: F405 & F411 versions of the BluePill

Yes, it was in Sketchup v8 (the one that was still from Google, now obsolete).

It looks like the Collada format is loosing color information.

Anyway, there isn't much color in it: the body is a kind of mate greyish tin metal, there is a black plastic inner body with gold contacts + SMD pins.

Re: F405 & F411 versions of the BluePill

Yes, but this is just bending the pins for through-hole, the main body should be OK. OK I tried to download that file, but there is a whole load of license conditions which I'm not sure may preclude us from adding it to an open source project It may not look so pretty, but its probably easier to kn...

@racemaniac: If you are able to import Sketchup or Collada 3D files, I designed a nice microUSB connector here: https://3dwarehouse.sketchup.com/model/e83a36572fc55c5d2ef54a87ac85e99d/Micro-USB-B-Receptacle-Bottom-Mount-SMT-Lead-Free https://3dwarehouse.sketchup.com/warehouse/getpubliccontent?conten...
