Schematic for Nucleo STM32F072 has unconnected jumpers.
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 sol...
STM32 MCU UART TX current
I am connecting the STM32L4 MCU UART to silicon labs IC CP2105 (UART to USB converter). The UART to USB bridge is bus powered from the type C connector and the STM32 is separately powered from the battery. When the CP2105 is in off state ( No USB ca...
