Hello All, Just an FYI - to circle back to [this: ](https://github.com/arduino/ArduinoCore-mbed/issues/16) The PR for the MRK-RGB Shield is [here:](https://github.com/arduino-libraries/Arduino_MKRRGB/pull/6) And - in the meantime - you can clone [this:](https://github.com/jwestmoreland/Arduino_MKRRGB) and run your MKR-RGB shield on the H7. Just one jumper required and just uncomment: #define USING_PORTENTA_H7 in MKRRGBMatrix.h I've only currently tested using the 5x7 font thus far. If anyone's curious I made use of the shiftOut() function to make this work. Best Regards, John W.
