Now Teensy 4.0 is out and it would be really great to see grove shield for it. I think the shield could be back-compatible with the Teensy 3.2/3.6 as they have same form factor.
Hi Yokonav,
Thanks for the idea. What also need to be taken into consideration is software, develop a Grove shield for Teensy means we also need to develop the Grove library for RT1064, which is a lot more work than the hardware.
The good news is that we are developing Arduino and micropython support for RT1052, which is used in our Arch Mix https://www.seeedstudio.com/Arch-Mix-p-2901.html. And the software can also be used for RT1064. Maybe we really can make a Grove shield for Teensy4.0 later.
