2. Component Details

Configuration Note

The examples below use TimerCamera-X. Lens field of view may vary by model; use the camera model and pin assignments from the complete configuration for the specific device.

PSRAM

The camera frame buffer uses the official ESPHome PSRAM component:

psram:
  mode: quad
  speed: 80MHz 

OV3660 Camera

TimerCamera-X uses the official ESPHome ESP32 Camera component:

i2c:
  - id: bsp_i2c
    sda: GPIO12
    scl: GPIO14
  - id: cam_i2c
    sda: GPIO25
    scl: GPIO23

esp32_camera:
  name: OV3660 Camera
  external_clock:
    pin: GPIO27
    frequency: 20MHz
  i2c_id: cam_i2c
  data_pins: [GPIO32, GPIO35, GPIO34, GPIO5, GPIO39, GPIO18, GPIO36, GPIO19]
  vsync_pin: GPIO22
  href_pin: GPIO26
  pixel_clock_pin: GPIO21
  reset_pin: GPIO15
  resolution: 640x480
  jpeg_quality: 10 

RTC

The onboard RTC uses the official ESPHome BM8563 platform. The RTC is read at startup and written after Home Assistant synchronizes the time:

time:
  - platform: bm8563
    i2c_id: bsp_i2c
    update_interval: never
  - platform: homeassistant
    on_time_sync:
      then:
        - bm8563.write_time: 

Status LED

The blue status LED uses the LEDC Output and Monochromatic Light platforms:

output:
  - platform: ledc
    id: blue_led
    pin: GPIO2

light:
  - platform: monochromatic
    output: blue_led
    name: "Blue LED"
    restore_mode: RESTORE_DEFAULT_ON 

Battery Hold and Voltage Measurement

GPIO33 controls the battery power hold circuit. The pin is pulled high by default; when USB power is not connected, turning this switch off powers down the device:

switch:
  - platform: gpio
    id: bat_hold_pin
    name: "Battery Hold Pin"
    pin: GPIO33
    restore_mode: RESTORE_DEFAULT_ON 

TimerCamera-X and TimerCamera-F can read the battery voltage on GPIO38 with the official ESPHome ADC Sensor platform:

sensor:
  - platform: adc
    pin: GPIO38
    attenuation: 12dB
    name: "Battery Voltage"
    id: battery_voltage
    update_interval: 10s
    filters:
      - multiply: 1.51 

Battery Voltage Note

Battery voltage is meaningful only when external USB power is disconnected and GPIO33 remains high. Battery-percentage conversion is application-specific and is not included in the base driver configuration.
