 ## Coding conventions
 
 - **Constants**: use `from micropython import const` wrapper in `const.py` files.
+- **Imports**: explicit imports only (`from <module>.const import NAME1, NAME2`). Wildcard `import *` is not allowed.
 - **Naming**: `snake_case` for all methods and variables. Enforced by ruff (N802, N803, N806).
 - **Class inheritance**: `class Foo(object):` is the existing convention.
 - **Time**: use `from time import sleep_ms` (not `utime`, not `sleep()` with float seconds).
-- **Exceptions**: use `except Exception:` instead of bare `except:`.
-- **No debug `print()`** in production driver code.

+### Active ruff rules
+
+The full configuration is in `pyproject.toml`. Here is a summary of the active rule groups:
+
+| Group | Description |
+|-------|-------------|
+| A | Prevent shadowing Python builtins |
+| B | Flake8-bugbear: common bug patterns |
+| C4 / C90 | Comprehension style / McCabe cyclomatic complexity |
+| E / W | Pycodestyle errors and warnings |
+| F | Pyflakes (unused imports, undefined names, etc.) |
+| I | Import sorting (isort) |
+| N802, N803, N806 | PEP 8 naming: functions, arguments, and variables must be `snake_case` |
+| PL | Pylint (complexity thresholds: max-branches=25, max-statements=65, max-args=10) |
+| PERF | Perflint: performance anti-patterns |
+| SIM | Flake8-simplify: code simplification suggestions |
+| T20 | No `print()` in production code (excluded for examples and tests) |
+| RUF | Ruff-specific rules |
+
+### MicroPython-specific exceptions
+
+Some rules are ignored because MicroPython does not support the corresponding Python features:
+
+| Ignored rule | Reason |
+|--------------|--------|
+| SIM105 | `contextlib.suppress` is not available in MicroPython |
+| PIE810 | MicroPython does not support passing tuples to `.startswith()` / `.endswith()` |
+| SIM101 | `isinstance()` with merged tuple arguments is unreliable in MicroPython |
