I got a RedBoard Artemis ATP to start developing for a project. The peripherals I want to use are a 9" display from 4D Systems plus a few qwiic sensors.
I can run everything fine off of the USB-C connector on the RedBoard.
If I try to run things using a 12V supply connected to the RedBoard, the power converter chip gets quite hot.
If I unplug the display from the board, it runs cool.
According to the 4D docs, the display should be drawing 500-600mA
Is this expected?
