ok, so, roger: that connector that squonk42 has found is a really good example of a part where it's really really important to record it on a wiki.

why?

well... in 2 days time when racemaster comes back, there will be about... 2 or 3 more pages of discussion. he won't see any of that... so what we will be forced to do is: *remember* that the part is there, and do page-back, page-back, page-back, scroll, scroll, scroll... and eventually, if we're really lucky, not miss it, and be able to refer him to it.

however... if there was a wiki, which he'd bookmarked, we could just say "go look at the wiki reference section we added an excellent USB mid-mount connector"

wiki pages are *really important*. i would set one up however im doing so it makes my personal web server resources a permanent part of the stm32duino infrastructure, which i don't feel is appropriate for me to do.

[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 molex clone it's probably okay.
Yes, here is the corresponding query:
https://s.taobao.com/search?q=USB+5PIN% ... =price-asc

According to Google, "USB 5PIN沉板 MICRO 5P MK5P 沉板 0.8mm母座 四脚插 USB插座" translates into "USB 5PIN sink board MICRO 5P MK5P sink board 0.8mm female four feet plug USB socket", where "sink board" probably means "mid-mount" and "four feet plug" means "4 Through Hole Solder Tabs".

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:

2D drawing and 3D STEP files here:
http://www.alps.com/prod/info/E/HTML/Ta ... CE010.html

It can be found for 0.10 RMB on TaoBao from many vendors:
https://s.taobao.com/search?q=SKSGACE01 ... =price-asc

It could be interesting too to replace the tall and bulky BOOT header & jumpers by an additional similar button for BOOT0, much like the dual-button solution used on NodeMCU boards for RESET/FLASH (page 6):

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 switch was also connected to PB8:

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/dat ... SOCKET.xml
... Only 11.95 mm wide, meaning that it fits between the BP rows of pins... May be worth to provide the footprint on PCB bottom side (at least if there is still space), although they are not even expensive on TaoBao:

Guys, without creating any wiki, is really easy for the OP to modify the first post and add links to the relevant posts in the thread.

Roger, can you do that and bookmark posts like the one with the usb part in the first post? that's easy and effective, without consuming much time.
