Mmmm, new expansion buddy boards. Please allow me to make a
- 3 serial ports mounted horizontally like the client USB rather than
(as they are now) vertically, at both RS232 and TTL. (Yes, that's
different than the breakout board).
- Don't bother with client USB
- Power via normal port
- Power and ground via a molex pin like those on the very bottom right
of this picture:
- I2C via molex pins in the same fashion
- Heck, all of the GPIO pads converted to molex pins. But particularly
I2C. All available in the front of the board, and accessible via holes
in the box.
- Something that holds the Gumstix board better
- Bigger holes for risers (see the same picture)
- Regulated power out
And if we're going crazy, here's what I'd love to see in a buddy board:
a robotics buddy board. Basically take an existing BrainStem (my first
choice) and mold it into a buddy board. So it provides power, servo
power, Vcc out, I2C, multiple servos, digital ins, and analog ins.
This would be a very big win in the educational and research robotics
community. And some socketed, cheap H-bridges!
Also, 802.11 would be cute.
