  • Is the load capacitance of this Crystal 20pF? If so, wouldn’t it need 2, 30pF, caps, rather than the 22pF that people are recommending?

  • To get the auto-reset to work, can the DTR pin be directly connected to the reset pin of the atmega328, or does it need a capacitor connected in series before the reset pin as shown in the Arduino Breadboard Tutorial?

  • This is of course late, but for future reference, I believe that you shouldn’t hook up the logic side’s V+ to a 5V power. According to pololu ‘V+ pad on the logic side of the board gives you access to monitor the motor’s power supply’. Also since they mention the 5V line being able to supply a regulated 5V, my assumption is that the chip has a built in regulator that takes the Vin and supplies 5V to all the logic components. My reference is pololu’s website for this product: http://www.pololu.com/catalog/product/755

  • Wonder how these compare with Digilent’s newly released chipKit boards:
