What is the maximum size of the OpenMV Cam H7 SD card, is it 32GB or 64GB?

The datasheet [https://cdn.shopify.com/s/files/1/0803/9211/files/OpenMV-H7.pdf](https://cdn.shopify.com/s/files/1/0803/9211/files/OpenMV-H7.pdf) says 64GB, but the pinout image [https://cdn.shopify.com/s/files/1/0803/9211/files/cam-v4-pinout.png](https://cdn.shopify.com/s/files/1/0803/9211/files/cam-v4-pinout.png) on the kickstarter page says 32GB and hardware setup [3. Hardware Setup — MicroPython 1.15 documentation](http://docs.openmv.io/openmvcam/tutorial/hardware_setup.html) says 32GB.

thanks,  
Chris

64GBs cards work, but you should format it as exFAT it’s much faster for large SD cards.
