  • False advertising; just bought this board and it's not at all as described on the page or in the schematic. Oscillator is a wacky 14.7456MHz rather than 10MHz for running at max speed. Guess I have to buy a new oscillator if I want to run at max speed. Also, board has a bridge rectifier and requires +6VDC to operate rather than the readily available +5V it advertises. First order from Sparkfun, and maybe the last if I can't count on accurate specs.
