This project provides ESPHome YAML configurations to integrate it with Home Assistant.

​
Built-in hardware

  • 1.44” TFT display (ST7735) — shows device status, IP address, temperature
  • 6 capacitive touch buttons — exposed as binary sensors
  • Light sensor — ambient light percentage
  • Buzzer — PWM audio output
  • IR receiver (38 kHz) — remote control support
  • WiFi signal and uptime sensors
  • CPU temperature monitoring
  • Bluetooth proxy — extends Home Assistant BLE range

​
Expansion support

These peripherals connect to the board’s expansion headers:
  • LED matrix (WS2812) — GPIO12 output for LED strips (e.g., 32x8 = 256 LEDs)
  • Stepper motors (2x 28BYJ-48) — via MCP23009 I/O expander and ULN2004A drivers

​
Board revisions

The ED1 comes in two hardware revisions: Rev 1.0 and Rev 2.3. Core packages work on both revisions, but some peripherals differ between them. See the hardware overview for details.
