Re: Tiny castellated modules
I haven't tested any of the modules yet (I'll be doing a lot of assembly tomorrow and will report back). I had to reorder my 32U4 boards because I made a stupid mistake (eagle library I used didn't have a pad for the QFN package).
Also, if you are going to assemble these yourself, you'll probably need eagle to view the boards so you can see the names of the capacitors/resistors. I didn't have enough space on the boards themselves. I'll eventually update their respective github pages with placement diagrams.

thanks....
i've actually got Eagle (still learning and getting my head around it)....
i made some minor adjustment for my own personal help (apologies for this) just to make soldering a little easier....
this is a guide i did for myself, for when i come to put it together
i think i've got everything in the right place.....
thanks....

Re: Tiny castellated modules
Finished building the first USB module. It works (sort of)! It's recognized by the computer as a USB hub, but I get a device descriptor error when I plug something into it, so I've got to figure that out.

Re: Tiny castellated modules
IT WORKS. I reflowed it and did a better job cleaning off the flux. I also attached a device to the fourth port instead of the first. I'm going to test the rest of the ports tomorrow.
Edit: I made a STUPID mistake. I labelled 1+ and 1- improperly, hence why they didn't work when I tested them. Incredibly stupid but the board works entirely (all 4 ports).

Re: Tiny castellated modules
The 32u4 module seems interesting. There's a whole community around building mechanical keyboards (reddit.com/r/mechanicalkeyboards is a good place to start) and 32u4 microcontrollers are used as the controllers, usually with qmk (qmk.fm) firmware.
Is there an eagle part I could use to add this to boards?

I haven't been active for a while. I periodically check the forum and blog for interesting projects, but don't post very much.

Yup, I should add that to the main post. Castel Module LibraryMerlin04 wrote: ↑Mon Aug 20, 2018 11:30 amThe 32u4 module seems interesting.

Re: Tiny castellated modules
Could you add the microcontroller pin names alongside the arduino pin names in the schematic view?Sushi wrote: ↑Mon Aug 20, 2018 12:35 pmYup, I should add that to the main post. Castel Module Library

Sure, I'll do that in the next commit done.Merlin04 wrote: ↑Mon Aug 20, 2018 5:19 pmCould you add the microcontroller pin names alongside the arduino pin names in the schematic view?Sushi wrote: ↑Mon Aug 20, 2018 12:35 pmYup, I should add that to the main post. Castel Module Library
In other news, my PowerBoost castel boards just arrived. I've assembled one, but I need to run to the store to get a voltmeter before I can test it (RIP crappy voltmeter).

Re: Tiny castellated modules
Hm, PowerCastel isn't working as expected. Charging works fine but 5V output is only millivolts. I've ordered ceramic 100uF capacitors instead of the tantalum caps I was using. Adafruit uses those instead. I'm also going to assemble a second PowerCastel to see if it was just bad assembly.
