Last call for revision 4

We're running out of boards, so it's time to get a new batch.

Somewhere next week I will take a good look at the issue tracker and see what will be in Rev 4. So if you have things to add, now would be a good time to post something on the issue tracker.

(please do not post suggestions in the forum).

I will be working on the board in KiCad. If someone wants to review the board before it goes to Eurocircuits, please let me know!

The design for Rev4 has been made. The board has been uploaded to GitHub.

We need volunteers to have a good look at the board... please open the design in KiCAD and see if you find any (new?) bugs!

End of the week, I will order a new batch from Eurocircuits.

For KiCAD noobs, both the schematics and the board are available as SVG in GitHub:

Jaap: a few remarks: see issues.
1) 3v3 jumper is not required
2) Silkscreen location of MBED usb connector (and pin1)
3) 3v3 power requirement (>250mA) or place 5V on pololus (test?)
4) decoupling capacitors on pololus (underneath)
