## List available boards and defconfigs with Board Explorer
105+
106+
The NuttxBoardExplorer allows the user to retrieve a list of boards, which
107+
can be filtered by arch, soc or individual board. Each returned board has
108+
a list of all defconfigs, which can be iterated and its content can be retrieved.
109+
110+
This example demonstrates how to discover boards and defconfigs available
111+
in an existing NuttX repository using the lightweight helpers in
112+
`ntxbuild.nuttx`.
113+
114+
```python
115+
from pathlib import Path
116+
from ntxbuild.nuttx import NuttxBoardExplorer
117+
118+
# Path to the nuttx repository inside your nuttxspace
119+
nuttx_repo = Path.cwd() / "nuttx"
120+
121+
# Create a filter and list all boards for a specific architecture
122+
nbf = NuttxBoardExplorer(nuttx_repo)
123+
boards = nbf.set_arch("arm").boards
124+
125+
for board in boards:
126+
print(f"Board: {board.name} (arch={board.arch} soc={board.soc})")
127+
for cfg in board.defconfigs:
128+
print(f" - defconfig: {d.name}")
129+
# optionally read the defconfig content
130+
# print(d.content)
131+
132+
# You can also find boards by soc or by exact board name
133+
boards_by_soc = nbf.set_soc("stm32").boards
134+
boards_by_name = nbf.set_board("nuttx-stm32").boards
135+
```

## Board Explorer
43+
44+
The Board Explorer feature provides a simple way to discover and inspect
45+
the boards and available defconfigs inside a NuttX repository. It is available
46+
both through the CLI (commands that list boards) and the Python API
47+
(see `ntxbuild.nuttx` helpers).
48+
49+
- Quickly find which boards support a particular architecture or SoC.
50+
- Programmatically build a list of candidate boards for automated testing or
51+
CI matrix generation.
52+
- Provide a lightweight UI (or CLI output) that helps users choose a board
53+
and defconfig before running `start` or `build` commands.

## View Available Boards and Configs
83+
It is possible to quickly see a table of available boards for a SoC or defconfigs for a board.
84+
85+
For the board list, provide the SoC name as in `boards/<arch>/<soc>`.
86+
```bash
87+
$ ntxbuild list boards qemu
