- Display: works reliably with 
ili9342 - Touchscreen: works well with 
ft63x6, including virtual button regions (A/B/C) - MPU6886 IMU: provides data for accelerometer, gyroscope, and temperature. Temperature readings are erratic and inaccurate
 - Speaker: didn't work, but some config is provided
 - Microphone: untested
 - BM8563 RTC: not configured, no ESPHome component exists for it
