 **Please read: operating voltage**
 
-The microcontroller on the **Arduino Nano 33 BLE Sense Rev2** runs at 3.3V, which means that you must never apply more than 3.3V to its Digital and Analog pins. Care must be taken when connecting sensors and actuators to assure that this limit of 3.3V is never exceeded. Connecting higher voltage signals, like the 5V commonly used with the other Arduino boards, will damage the Arduino Nano 33 BLE Sense Rev2.
+The Arduino Nano 33 BLE Sense Rev2 operates at +3.3 VDC. Never apply more than +3.3 VDC to its digital and analog pins, as higher voltages will permanently damage the board. 
 
-To avoid such risk with existing projects, where you should be able to pull out a Nano and replace it with the new Nano 33 BLE Sense Rev2, we have the 5V pin on the header, positioned between RST and A7 that is not connected as default factory setting. This means that if you have a design that takes 5V from that pin, it won't work immediately, as a precaution we put in place to draw your attention to the 3.3V compliance on digital and analog inputs.
+The 5V pin (between RST and A7) is not connected by default as a safety precaution. To enable the +5 VDC output on this pin:
 
-5V on that pin is available only when two conditions are met: you make a solder bridge on the two pads marked as VUSB and you power the Nano 33 BLE Sense Rev2 through the USB port. If you power the board from the VIN pin, you won't get any regulated 5V and therefore even if you do the solder bridge, nothing will come out of that 5V pin. The 3.3V, on the other hand, is always available and supports enough current to drive your sensors. Please make your designs so that sensors and actuators are driven with 3.3V and work with 3.3V digital IO levels. 5V is now an option for many modules and 3.3V is becoming the standard voltage for electronic ICs.
+1. Create a solder bridge on the VUSB pads
+2. Power the board via USB (+5 VDC will not be available when powered through VIN)
+
+The 3V3 pin is always available and provides sufficient current for sensors and actuators. When interfacing with +5 VDC systems, use appropriate level shifters to protect the board's inputs.
