I'm a little confused by the powering arrangements of the MKR 1010 WiFi. I need to power it on a breadboard from an external power supply. I will not be using a LiPo battery and I need it to work when the USB is disconnected.
Assuming there is no battery or USB connected, I think I need to apply power on the
Vin pin (the pinout diagram on
arduino.cc shows this as an input pin and
5V as an output pin). However, the
5V pin has a resettable fuse inline whereas
Vin does not, which to me is counterintuitive.
So my questions are twofold:
- What is the correct pin for supplying external power, and
- What is the correct voltage to apply
