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....

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.

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).

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 Library

Could you add the microcontroller pin names alongside the arduino pin names in the schematic view?

Sure, I'll do that in the next commit done.

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).

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.
