Re: F405 & F411 versions of the BluePill

what i am wondering though is on github or so how we'll handle the pcb project, unlike code it's something that doesn't lend itself to easy merging ^^' or will i keep doing all the changes to the pcb? Only put it in github so people could access the latest version from the same place all the time. ...

Re: F405 & F411 versions of the BluePill

KiCad uses VRML 2.0 with the WRL extension It seems that KiCad does not support all types of VRML but that the version exported by FreeCAD works OK. Also Wings3D can export in the correct type of VRML But as I was creating my models in OpenSCAD, the best way I found was to open the SCAD file in Free...

i meant use the circulation fan out of one, not using a fan oven :lol:

OK

I tried to get hold of a cooker fan, but they were not easy to source.

I see Amazon in the US has them for $11 USD, but I can't find a local supplier in Australia.

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...

Re: F405 & F411 versions of the BluePill

One other thing ...

I noticed on the Teensy 3.6 that it has SMD pads on the bottom, because the MCU has more GPIOs etc than there are though holes on the PCB

Looking at the PCB layout, there may be scope to do the same thing for some of the unused pins

Re: F405 & F411 versions of the BluePill

That model may need some changes as the fixing pins probably need to be bent to go through the PCB

Re: F405 & F411 versions of the BluePill

OK.

I'll add those files to the repo

Edit.

Those files should now be in the repo

I just put them in the root of the repo.

PS. I think we need a BOM CSV file so that we can calculate the price etc

No point doing gerbers yet, as the design is not stable

Re: Making your own pcb's.

I think a fan is essential. The problem is most domestic ovens do not heat up fast enough. I know the oven in my kitchen seems to take around 10 mins to get to 220 deg, which is far to slow. The oven needs to have the ability to get to almost the reflow temperature in a reasonable time frame, e.g. p...

Re: F405 & F411 versions of the BluePill

OK

In case its easier for people to manage this via github, I've added @racemaniacs board to my existing github repo

https://github.com/rogerclarkmelbourne/ ... ill_Boards

I removed my abandoned attempts, and I've renamed the KiCad version of the STM32Stamp board, back to its original name.
