Subject: PMDX-131 should we revise for larger G202 drivers?
Shortly after the PMDX-131 breakout/motherboard combo for Gecko
stepper motor drivers was announced there were new G202/212 drivers
announced by Geckodrive. These new drivers have many great features,
but are 3.125" wide versus the 2.5" footprint of the older Geckodrive
products.
PMDX has been contacted by many potential users about using the PMDX-
131 with the new drivers. We at PMDX need to decide if we should
proceed with the existing PMDX-131 design or revamp it to allow for
the wider G202/212 drives. The primary issue is the overall length of
the assembly. Currently the assembly consisting of the PMDX-131 and
Gecko drivers is 11.2" long. A revised PMDX-131 to support the
G202/212 would need to be about 13" long and would cost about $181.00
instead of the previously announced $174.00.
We are seeking feedback from potential customers. Should we delay
introduction and revise the board?

[Can't you come up with a new version to accomodate the new drives while
still keeping the original version available? Some people will want to use
the older-style 201/210 Geckos, which Mariss apparently will keep selling,
because they're cheaper. Most of the advantages of the new drives are for
people putting together their own systems, who don't want to burn up their
drives in the trial-and error process of figuring things out. For an OEM,
surely part of your intended market for these boards, these advantages
likely won't outweigh the price difference. The larger boards will probably
require a bigger and more expensive enclosure as well. It seems like you've
done all the work of putting this together the way it is; why waste that?
I'd say keep the 131 as is, and call the new one a PMDX-132. ]
