+# Legacy Pico Dashboard
+
+This directory contains the archived Raspberry Pi Pico dashboard implementation.
+
+It is no longer active project firmware.
+
+## Why this was archived
+
+The current dashboard direction is the Waveshare ESP32-S3 touchscreen dashboard communicating with the Cargo ESP32 over WiFi/HTTP REST.
+
+The Pico dashboard path was based around:
+
+- Raspberry Pi Pico / Pico 2 W
+- UART communication
+- Pico-specific display/touch/buzzer hardware
+- Python/MicroPython-style dashboard structure
+
+That architecture is no longer the current plan.
+
+## What may still be useful
+
+Some concepts may still be useful as reference material when building the ESP32-S3 dashboard:
+
+- HTTP client flow
+- State model ideas
+- Alarm logic concepts
+- Screen/view-model structure
+- API payload expectations
+
+Treat this as reference only. Do not add new active dashboard code here.
+
+## Current dashboard target
+
+Active dashboard work should go under:
+
+    firmware/esp32-s3-dashboard/
+
+or another explicitly approved ESP32-S3 dashboard firmware location.
