+**Low Power I/Os**
+
+As reported in the table above, Nicla boards have a set of Low Power I/Os.
+These I/Os are translated through an 8-Bit Bidirectional Voltage-Level Shifter with Auto Direction Sensing (check [TXB0108 datasheet](https://www.ti.com/product/TXB0108) for further info) and powered by VDDIO_EXT. This shifter is able to convert logic levels from inputs operating at 3.3V or less down to 1.8V (i.e. microcontroller operating voltage). However, it does not feature directional pins, since each input and output connected to it can detect and shift signals in either direction independently and automatically. As a consequence, the nominal behavior of these pins is guaranteed only when they are connected to a CMOS logic.
+In the next section, the interaction with Low Power pins as input or output is described.
+
+**Low Power Input Pins**
+
+Any input device operating with a voltage less or equal to 3.3V can be connected to the Low Power pins. The integrated Voltage-Level shifter will automatically detect that an input device has been connected to the pin and it will guarantee the conversion from 3.3.V to 1.8V, i.e. microcontroller operating voltage, to properly interface with the Nicla boards.
+
+**Low Power Output Pins**
+
+Any Low Power device can be directly connected to the Low-Power pins in case it does not absorb any current. The Voltage-Level shifter will automatically detect that an output device has been connected to the pin and switch the port accordingly. The output voltage is digital and its value depends on how VDDIO_EXT has been programmed via software: VDDIO_EXT can be switched off or switched on either at 1.8V or 3.3V.
+On the other hand, if the connected output device needs to absorb current (e.g. LEDs, resistive loads, buzzers etc.), the user should connect a MOSFET or a buffer to guarantee the required current flow. A reference schematics showing how to connect an LED to a Low-Power pin through a MOSFET is reported below.

### Fins
Nicla boards have a set of fins interleaved among headers that are mainly for debug and initial programming. These pins are arranged so that they can easily be contacted by inserting the board in a 1.27mm/50 mil dual row header that would allow firmly contacting the fins along with header pins, provided no header has been soldered on it.
