Low-Noise ADC Pins
^^^^^^^^^^^^^^^^^^
-Analog input pins D4 — D11 on the Maple Mini generally offer
-lower-noise ADC performance than D3. If you’re concerned about
-getting good ADC readings, we recommend using one of these pins to
-take your measurements.
-
Maple Mini has an electrically isolated analog power plane with its
own regulator, and a geometrically isolated ground plane, connected to
-the digital plane by an inductor. Pins D4 — D11 are laid out to
-correspond with these analog planes, and our measurements indicate
-that they generally have the lowest noise of all the analog lines.
-However, analog performance may vary depending upon the activity of
-the other GPIOs. Consult the :ref:`Maple Mini hardware design files
-<maple-mini-hardware>` for more details.
