+# ATK-DNESP32S3-BOX0
+
+Board support for the ALIENTEK ATK-DNESP32S3-BOX0.
+
+This port follows the pin map used by `xiaozhi-esp32/main/boards/atk-dnesp32s3-box0`.
+It declares power rails, battery/charging monitor, ST7789 LCD, LEDC backlight,
+ES8311 audio input/output, and three GPIO buttons.
+
+TF card support is intentionally not declared because the referenced Xiaozhi
+BOX0 board files do not define TF card pins. Add it only after the BOX0
+schematic or measured pin map is confirmed.
+
+## Build
+
+```bash
+cd application/edge_agent
+idf.py set-target esp32s3
+idf.py gen-bmgr-config -c ./boards -b atk_dnesp32s3_box0
+idf.py build
+idf.py merge-bin -o build/atk_dnesp32s3_box0_merged.bin
+```
+
+If the active ESP-IDF does not provide `idf.py merge-bin`, use
+`esptool.py merge_bin` with the generated build flash arguments.
+
+## Boot checkpoints
+
+- `BOX0 power manager initialized`
+- FATFS mounted at `/fatfs`
+- Wi-Fi manager starts
+- Board manager initializes `display_lcd`, `lcd_brightness`, `audio_dac`, and `audio_adc`
+
+## Hardware smoke test
+
+- The ST7789 backlight turns on and the display shows the Agent UI or a Lua display demo.
+- ES8311 playback and microphone input initialize without I2S or codec errors.
+- Buttons are readable from Lua with:
+
+```lua
+local button = require("button")
+local right = button.new(0, 0)
+local middle = button.new(4, 0)
+local left = button.new(3, 0)
+```
+
+- Battery logs show plausible ADC, percentage, and charging state values.
