How to power the Arduino Nano 33 IoT? According to the box, the Arduino Nano 33 IoT can be powered by the USB connector (5V) or through the Vin pin (4.5V - 21V) while its operating voltage is 3.3V.

As seen in the above schematic, a 5-V DC supply from the USB connector (USB) is routed to two 10-Ω/5-W power resistors (R1 and R2) through an SPST switch (S1) followed by an SPDT switch (S2). Here, S1 ...
