I've already seen that on my (beta) board and reported it, but it seems there was not enough time to fix/investigate that.

The spikes can be lowered a bit by disabling the high-pass filter (-> HP off). Please change the gain from 5*16 to 16*5. The overall gain of the BLUE system is really high and the first stage should always be higher than the second one.

Thanks Tobi, disabling the high-pass filter did the trick. The overall noise also decreased.
