The controller could nail the timing - RT Linux can't

where did you order them from? we're a beta team, and would like to take one out for spin early; the earlier we wring out the wrinkles, the better....

I ordered a small batch of boards from a chinese board shop. The first boards have a design flaw that make them unusable. But they are perfect for fit up testing. I haven't made the corrected version yet, because I haven't been around beta hardware yet.

I'll gladly send you a board to plug in, if you can post pictures of it installed here.

Once fit and clearances are verified, I'll get another small batch made of the corrected version.

PM me an address and I'll get one sent off.

Bombsquad let me test the MXP board for fitup last weekend at GRC. Thanks.

Looks good, but now I'm not sure we'll be allowed to use the MXP port next year. Apparently there is debate about the safety of the port. Not sure I get that. Copper on a board is the same as copper in a wire to me.

I guess we could add analog inputs through the i2c or spi busses.
