CiferTech's CYD (Cheap Yellow Display) build. ESP32 with 2.8" resistive touchscreen, SD card slot, RGB LED. CYD-specific pin mappings and touch controls.

REQUIREMENTS

  • Chrome 89+ or Edge 89+ (Web Serial API required)
  • CiferTech ESP32-DIV V1.x, V2.0, or compatible CYD board
  • USB cable — V1 uses CH340/CP2102 serial, V2 uses CP210x serial
  • Hold BOOT during flash if board doesn't auto-enter download mode
  • V2: enter download mode via BOOT+RESET sequence
