I watched the video and am curious about the protocol loading apps from add-ons. Do the resistors j7st say what k8nd of connection is used (i2c, serial, etc)?

Also, I've been looking for cyberdeck and clamshell designs using CM4 and am impressed with how you sourced the keyboard. Is there a reason the replace the matrix chip with an i2c extender and not use the original chip?
