    Greetings,
    A point of minor confusion, in the manual for AVR, the board shown has only three jumpers on it (the one I own, and can't get to work) , however, in the next view of the AVR, it shows four, with a new footprint. What gives? :?

    Hi,
    I think there is no difference in the functionality of the boards shown in the 2 different images. They may be different revisions?
    If you look closely at the connection to the center of the feedback pots, you will see that the pcb track layout has been modified to simplify the board. The extra jumper jumps over this track in the other version.
    Just install the jumpers and all should be OK on both versions of the board as it replicates the wiring of the other board anyway! :)
