Unit PoE CAM-W v1.1 ESPHome Integration

The Unit PoE CAM-W v1.1 ESPHome integration includes W5500 networking, the OV3660 camera, a button, and a status LED.

1. Device Overview

2. Component Details

PSRAM

The camera frame buffer uses the official ESPHome PSRAM component:

psram:
  mode: quad
  speed: 80MHz

Ethernet and Wi-Fi

Wired networking uses the official ESPHome Ethernet component with a W5500 controller. Ethernet is enabled by default in the example. Wi-Fi remains available as an optional configuration, but only one network interface can be enabled at a time.

ethernet:
  type: W5500
  clk_pin: GPIO23
  mosi_pin: GPIO13
  miso_pin: GPIO38
  cs_pin: GPIO4
  clock_speed: 20MHz

OV3660 Camera

The camera uses the official ESPHome ESP32 Camera component. The I2C control bus uses GPIO14/GPIO12, the external clock is output on GPIO27, and the camera data and synchronization pins are fixed by the board wiring.

i2c:
  - id: cam_i2c
    sda: GPIO14
    scl:
      number: GPIO12
      ignore_strapping_warning: true

esp32_camera:
  name: "OV3660 Camera"
  i2c_id: cam_i2c
  external_clock:
    pin: GPIO27
    frequency: 20MHz
  data_pins: [GPIO32, GPIO35, GPIO34, GPIO5, GPIO39, GPIO18, GPIO36, GPIO19]
  vsync_pin: GPIO22
  href_pin: GPIO26
  pixel_clock_pin: GPIO21
  reset_pin:
    number: GPIO15
    ignore_strapping_warning: true

Button and Status LED

The button uses the official ESPHome GPIO Binary Sensor platform and is read through GPIO37. The status LED is driven by LEDC Output and exposed as a dimmable entity through Monochromatic Light:

binary_sensor:
  - platform: gpio
    name: "Button"
    pin:
      number: GPIO37
      inverted: true

output:
  - platform: ledc
    pin:
      number: GPIO0
      inverted: true
      ignore_strapping_warning: true
    id: status_led

light:
  - platform: monochromatic
    output: status_led
    name: "Status LED"
    restore_mode: RESTORE_DEFAULT_ON
