+## Change the PWM resolution
+
+Depending on your board's core, you can modify the resolution of PWM signals using the [`analogWriteResolution()`](https://docs.arduino.cc/language-reference/en/functions/analog-io/analogWriteResolution/) function. By default, the resolution is 8 bits, meaning that values passed to the `analogWrite()` function range between 0 and 255, which ensures backward compatibility with AVR-based boards.
+
+To change the resolution, use `analogWriteResolution(bits)`, where `bits` determines the resolution in bits, ranging from 1 to 32. [See an example code](https://docs.arduino.cc/language-reference/en/functions/analog-io/analogWriteResolution/#example-code).
+
+> [!NOTE]
+> If the resolution set is higher than your board’s capabilities, the extra bits will be discarded. If it's lower than your board’s capabilities, the missing bits will be padded with zeros.
