 The **Arduino Nicla Sense ME** can be powered via micro USB (J7), ESLOV (J5) or VIN. This is converted into the relevant voltages via the BQ2512BAYFPR IC (U9). A Schottky diode provides reverse polarity protection to the USB and ESLOV voltages. When voltage is supplied via the microUSB, a linear 3.3V regulator also provides power to the SAMD11 microcontroller used for programming the board as well as for JTAG and SWD. The LED driver (U8) and RGB Leds (DL1) are driven by a boost voltage of 5V. All other components operate off the 1.8V rail regulated by a buck converter. PMID acts as an OR switch between VIN and BATT and operates the LED driver. All I/O broken out to the pins are fed through a bi-direction voltage translator running at V<sub>DDIO_EXT</sub>.
