Buy an Axon, Axon II, or Axon Mote and build a great robot, while helping to support SoR.

but give no idea as to what port/pin on the controller is actually used - obviously a 'best kept' duino secret. No schematics / no info - just dust.
but at about 4x the amount of money as an arduino, is it really worth it from a money standpoint?
Oh and madsci1016, Webbot was referring to the poor Arduino/imitation board mask labeling (you'd have to manually follow the traces to determine what plugs into which pin of the ATmega).
The others just say this is 'Pin 4' - but give no idea as to what port/pin on the controller is actually used -
Also, In my opinion, the Arduino's have a better USB <-> Uart chip (FDTI) than the Axon. (sorry Admin) And I have heard this from other SoR members. The FDTI has more features, including being able to be used as a bit-bang AVR programmer. Hell, if the Axon 3 switched to using a FDTI chip, you could market that it has a built in back up hardware programmer if the bootloader gets corrupted.

No schematics / no info - just dust. Actually, http://www.arduino.cc/en/Hacking/PinMapping168It's on their reference page. But, To add the same functionality the Axon already has (like webbot was saying), requires rather overpriced shields, which increase the price.

They count pins clockwise . Not alphabetical as it goes D then B, But opens more:-1. Can it only cope wth 28 pin dip2. What are digital/analog pins for say an ATMega32 dip 40 or ATmega261 TQFP or ATMega640 TQFP.Is there a general rule for any processor/package => magical 'duino digital pin number?

uh, I think u guys are missing the question.is the axon II 3x better than a arduino mega for 3x the money
