    Warning to those who will try to program WiTilt with custom firmware and AVRISP mkII programmer. Sparkfun put 5V Vcc on the programming header (pin2)which makes AVRISP think that the Atmega328p on the board runs at 5V while in fact it runs at 3.3V. That causes AVRISP to use wrong logic levels. AVR Studio gives the message “there seems to be short circuit on the isp connector” and Avrdude gives unspecified error with one programmer I tried and works intermittently with another. You can use about 300 Ohm resistors in series with MISO, MOSI and RST lines (I read that this helped someone with similar problems but have not tried myself) or put 3.3V on pin 2 of the connector which worked for me.

    So, what hardware is it: Atmega8@10MHz as the datasheet and schematics say or Atmega168@8MHz as the firmware source code says? Does it run at 56k (this webpage) or 115k (datasheet, schematics, source code)? Can you put on this page the firmware and schematics that both are consistent with the hardware you sell so that I know what I am paying $200 for?<br />

No public wish lists :(
