First power-on test with the xicoolee 7.3" Spectra 6 display and ESP32-S3-DevKitC-1.

Tasks:

Wire PH2.0 connector to ESP32-S3 per pin assignments in config.h
Verify BUSY pin polarity (expected: active LOW)
Confirm GxEPD2 GDEP073E01 init sequence works (if not, may need GDEY073D46)
Test full refresh cycle — should take ~15 seconds
Verify all 6 colors render correctly (black, white, red, green, blue, yellow)
Adjust GPIO pin assignments if needed

Display panel: GDEP073E01 (Spectra 6, 800x480)
Driver board: xicoolee (Amazon B0F8NF68X7) — likely Waveshare clone
