Re: F405 & F411 versions of the BluePill

Roger perhaps a new section in the Wiki for this board, which hopefully will be a reality soon and need a page in the wiki anyway, could have that "research" section?

Re: Making your own pcb's.

0.2mm is the thinnest I can print, but metal stencils seems to be around that thickness too. Will have to test and see what happens... Woud you say the T-962 is not worth it even with the open source firmware and cold junction modification? I have been reading on modifying a toaster oven, and seems ...

Re: F405 & F411 versions of the BluePill

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.

Re: Making your own pcb's.

Well, yesterday after an hour placing little bits of solder and components in the board, I tried the skillet method. This is a large board, 100x140mm. The solder went fine, but overheated in the center, because the skillet was not totally flat, and burnt the botton of the board. Amazingly enough, al...

Re: Making your own pcb's.

That idea doesn't seem so mad to me... it makes sense. You dont even need an oven, or a functional one to start with, just a good enough enclosure.
I'll do some search in google to see if someone has experimented with that.

Re: Making your own pcb's.

Reviving this old thread since it's all related.

Does anyone has link to a good cheap solder paste syringe for a few boards?

And has anyone successfully made a reflow oven out of a toaster oven?

I'm about to try the skillet method, but don't want to "cook" the boards if there is some better way...

I saw this stm32 version, but may not be for the F030:

May give you a head start if you can't find an F030 version. Not sure how large

Re: F405 & F411 versions of the BluePill

http://wiki.stm32duino.com/index.php?title=Blue_Pill pinout's towards the bottom. i did the analysis a couple days ago: for pin-compatibility / interoperability with pre-existing bluepill shields there is no other option but to use this particular pin as GPIO. right at the beginning of the thread (...

Re: F405 & F411 versions of the BluePill

Regarding the 1k resistor, if it's planned between the USB ID pin and the header pad, then it would not affect if the user doesn't use USB on the go. Something like (where the dashes is the electrical connection): USB ID PIN------1k------header_pin------MCU PIN. If nothing is connected in the USB co...

There is cmsis-dap, which I understand is open source and similar capabilities to ST-Link.
I have seen it used in some Nucleo clones coming from China, but can't confirm if it provides the exact same capabilities (debugging, serial, mass storage).
