There is no planned Pico dashboard path. Existing Pico/UART files are legacy artifacts unless explicitly revived later.
UART JSON remains optional for diagnostics or alternate clients. New dashboard work should target the Waveshare ESP32-S3 display and the HTTP API.
## Current communications and GPIO decision
Active dashboard communication is WiFi/HTTP using `/api/v1`.
The old Pico/dashboard UART path is retired from active hardware use. USB Serial remains available for development, debug, and manual configuration from a computer.
Current Cargo ESP32 GPIO plan:
- GPIO 16: Relay 1 trigger output
- GPIO 17: Relay 2 trigger output
- GPIO 4: DS18B20 OneWire temperature bus
- GPIO 34: Ignition sense input
- GPIO 21: SSD1306 OLED I2C SDA
- GPIO 22: SSD1306 OLED I2C SCL
- GPIO 25: OLED setup/status button
