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

Apply a square wave to XTAL1 (say 125KHz, 250KHz, etc). Ground to ground.
First, where is XTAL1?
Next, how do I create a square wave? Can I do it with another Axon?
QuoteFirst, where is XTAL1? There are only two pins on a crystal, so that narrows it down! Then just see the pinout in the datasheet, and/or the schematic - also in the Axon datasheet.QuoteNext, how do I create a square wave? Can I do it with another Axon?Any microcontroller can do it - just use PWM. Or find a function generator in a lab.A 555 timer IC can do it, too.
I know it mentions 125KHz, 250KHz but I'm not sure how to translate that into microseconds.
should the bricked Axon be powered?
