RTC VBAT pin
I was wondering if there is any option in a future revision of the K64F board to possibly route the VBAT trace (currently on the unpopulated J23 header) to one of the NC pins on the J3 power header?
This will enable us to keep the RTC time even when the board is powered down (this was possible with the LPC1768 mbed board).
Sure, I can easily solder a jumper wire on the board myself, but I use this in an educational setting and have classes of 100+ students. I do not imagine cutting traces and soldering jumper wires on development boards with such a large group will end well...
