I don't know yet. There may be some surface mount logic used, which would
rule out kits.
There's also much the same effort involved in handling ordering, payment,
packing and shipping for a kit as for a complete board, so there may not be
much saving.
The first layout for the expansion board didn't lend itself to automated
stuffing, so it needs a bit of a redesign.
