Adds a DIY build configuration for the ESP32-S3-DevKitC-1 (WROOM-1-N8R8) with an ST7789 1.14" 135*240 SPI display, OV2640 camera and three microswitch buttons.

Files added:

  • configs/sdkconfig_diycam_esp32s3devkitc1.defaults - sdkconfig defaults for the build
  • diy/esp32s3-devkitc1/README.md - wiring guide with pin tables for display, camera and buttons
  • diy/img/esp32s3-devkitc1.jpg - photo of the assembled hardware

Files modified:

  • diy/README.md - added ESP32-S3-DevKitC-1 entry under Camera-Enabled Hardware Options

Uses BOARD_TYPE_CUSTOM on ESP32-S3 with the existing partitionss3.csv partition table. Tested and working: display, buttons, camera (QR scanning), and BLE pairing with Blockstream Green all confirmed.

If accepted, this board would also be a candidate for the DIY web flasher. Binaries to be built and published by Blockstream.
