EETimes has
reported that the
robostix expansion board for the
gumstix platform will be released today, but according to Gumstix it will most likely be released next week.
I can't wait to get my hands on a gumstix with this expansion board. My plans for building my own expansion board using the
Atmel ATMega128 have now been put on the back burner, no need to re-invent the wheel when you can buy one on the internet. This may be a tiny bit more expensive, but it will cut my
UAV design time down so I think it's worth it. This expansion board will allow the control of servos and motors quite easily ( 6 PWM channels ). There is no rs232 interface directly from the ATMega128 on this board, but if I really need to use the chip in another PCB I can just pick one up from digikey for about $15 USD. I'm going to play around with a friend's ATMega dev kit (STK500) this weekend and see if I can get a servo moving or maybe just an LED blinking. I'll post some pics if I do.
