2. Component Details

PSRAM

The camera frame buffer uses the official ESPHome PSRAM component:

psram:
  mode: octal
  speed: 80MHz 

Status LED

The status LED uses the official ESPHome GPIO Switch component. GPIO14 is active low, and the LED is enabled by default after startup.

switch:
  - platform: gpio
    name: "Active LED"
    pin:
      number: GPIO14
      inverted: true
    restore_mode: ALWAYS_ON 

PY260 Camera

The PY260 uses the official ESPHome ESP32 Camera component:

i2c:
  - id: camera_i2c
    sda: GPIO17
    scl: GPIO41
    scan: true

esp32_camera:
  name: "PY260 camera"
  external_clock:
    pin: GPIO11
    frequency: 20MHz
  i2c_id: camera_i2c
  data_pins: [GPIO6, GPIO15, GPIO16, GPIO7, GPIO5, GPIO10, GPIO4, GPIO13]
  vsync_pin: GPIO42
  href_pin: GPIO18
  pixel_clock_pin: GPIO12
  reset_pin: GPIO21
  resolution: 320x240
  jpeg_quality: 12
