And because designs use that platform,
- it is more expensive
- it is less functional
- it requires multiple daughtercards to add the missing functionality
- each external board means adding connectors which adds to cost
- it requires a large "motherboard" (backplane) for those daughtercards
- each daughtercard means creating additional small PCB's
- lack of functionality means using a separate more expensive
controller: the raspberry pi
- and then raspberry pi itself is designed to be a television
computer, not an embedded host for peripheral boards
- it requires much more silicon resources than other choices otherwise would


But sure, it is neophyte-friendly and designed for lower-division education.


Considering the evolver mandates custom PCB's anyway, for the multiple
daughtercards, the use of a generalized and generic platform is just a
bad choice. The better solution would be to pick a more powerful
platform at the start and not require a custom PCB, or avoid generic
platforms and put a fully-functional controller on the custom PCB's.
They made the wrong initial design choices for what purpose, was it so
that makers could buy all their supplies through ladyada? If so that
is definitely a bad set of product requirements, to restate again,
since they require so much further fabrication to build the project.
(Laser-cut acrylic.. Tapping aluminum pipe for 4-40 thread, etc..
Double-sided PCB's with odd shapes, etc.. )
