Schematic for Nucleo STM32F072 has unconnected jumpers.

[EThay.1]

I've noticed that the Nucleo STM32F072 has two jumpers (CN11 and CN12) that connect ground to ground. Does anyone know why this is? Are these jumpers used on another Nucleo board, and just hang out on the STM32F072 like a lot of the unconnected solder bridges?

Thanks.

These are just two courtesy spare jumpers, provided in case you'd need to short some of the pins on the headers, e.g. BOOT0... it's even documented:

Wow I definitely missed that in the reference manual. Thanks for showing me!

Place to park them, that gets placed in manufacture, and convenient for ground clamping a scope probe.
