Will the GPIO Hackerboard be available for the XL ?
XL was the flagship at some point, and I still think it is... but it's not really extensible beside the overpriced enclosure.
Will the GPIO Hackerboard of the new Core One be available for the XL ?
While the presentation of the Core One specifies that "Prusa make extensible products", it feels the XL is pretty limited in extensibility so far... despite the higher price tag in the industry (for "consumer" products)
RE: Will the GPIO Hackerboard be available for the XL ?
The GPIO Hackerboard is also available for the MK4S because the connector is (and always has been) on the x-Buddy board. Not sure if the MK4 mode of the current x-Buddy firmware supports the GPIO board. I also don't know if the XL electronics have the I2C connector (Prusa haven't published the schematics yet) that the GPIO Hackerboard plugs into.
