4.9 JP1 (Idd)
Jumper JP1, labeled Idd, allows the consumption of STM32F407VGT6 to be measured by
removing the jumper and connecting an ammeter.
• Jumper on: STM32F407VGT6 is powered (default).
• Jumper off: an ammeter must be connected to measure the STM32F407VGT6 current,
(if there is no ammeter, the STM32F407VGT6 is not powered).
