3.1 Power supply selection
The 5 V power supply of AT-START-F407 can be provided through a USB cable (either through the
USB connector CN6 on the AT-Link-EZ or USB connector CN1 on the AT-START-F407), or
through an external 5 V power supply (E5V), or by an external 7~12 V power supply (VIN) via 5V
voltage regulator (U1) on the board. In this case, the 5 V power supply provides the 3.3 V power
required by the microcontrollers and peripherals by means of the 3.3 V voltage regulator (U2) on
the board.
The 5 V pin of J4 or J7 can also be used as an input power source. The AT-START-F407 board
must be powered by a 5 V power supply unit.
The 3.3 V pin of J4 or the VDD pin of J1 and J2 can also be directly used as 3.3 V input power
supply. AT-START-F407 board must be powered by a 3.3 V power supply unit.
Note: Unless 5 V is provided through the USB connector (CN6) on the AT-Link-EZ, the AT-Link-EZ will
not be powered by other power supply methods.
When another application board is connected to J4, the VIN, 5 V and 3.3 V pins can be used as
output power; 5V pin of J7 used as 5 V output power; the VDD pin of J1 and J2 used as 3.3 V
output power.
3.2 IDD
In the event of JP3 OFF (symbol IDD) and R13 OFF, it is allowed to connect an ammeter to
measure the power consumption of AT32F407VGT7.

JP3 OFF, R13 ON
AT32F407VGT7 is powered. (Default setting, and JP3 plug is not mounted before shipping)

JP3 ON, R13 OFF
AT32F407VGT7 is powered.

JP3 OFF, R13 OFF
An ammeter must be connected to measure the power consumption of AT32F407VGT77 (if
there is no ammeter, the AT32F407VGT7 cannot be powered).
