Compatability with 3.3V IO / Adafruit Grand Central

[RobotZwrrl]

Hi there,
Is the InkShield compatible with Arduino derivatives that use 3.3V on IO pins, rather than 5V? Need to see if it works with the Adafruit Grand Central.
Thanks!

@RobotGrrl I have a feeling you won't be getting an answer, maybe ever, in my research for open source inket printers, I checked every page from / relating to him and the latest activity was on twitter in 2018, so .. either they left the internet, switched all accounts or ..

I'm also researching at open source inket printers. It seems to be very unlikely to have a open sourced colored inkject(polyjet) system in the future. The best hope might use the MEMS tech to develop a very slow one but support pre mix in the head. I'm working in ShanghaiTech univerisity so this solution might be the only possible for me.
