Limitations

CAN operation is exclusive to BOOT0 and motor control connector 2.
5.12.2

Operating voltage

The supply voltage for STM32G474E-EVAL CAN operation must be more than 1.8 V.
5.13

CN5 and CN6 extension connectors

The CN5 and CN6 headers complement to give access to all GPIOs of the
STM32G474QET6 microcontroller. In addition to GPIOs, the following signals and power
supply lines are also routed on CN5 or CN6:
•
GND
•
5V
• 5V_D
•
VDD
• RESET#
•
Clock terminals PC14-OSC32_IN, PC15-OSC32_OUT, PF0-OSC_IN, PF1-OSC_OUT
Each header has two rows of 30 pins, with 1.27 mm pitch and 2.54 mm row spacing. For
extension modules, SAMTEC RSM-130-02-L-D-xxx and SMS-130-x-x-D can be
recommended as SMD and through-hole receptacles, respectively (x is a wild card).

User LEDs

Four general-purpose color LEDs (LD1, LD2, LD3, LD4) are available as light indicators.
Each LED is emitting light with a low level of the corresponding ports of the
STM32G474QET6 MCU.
The LD1 and LD3 LEDs are exclusive to MC operation. MFX_GPIO6 and MFX_GPIO7
control LD2 and LD4.

Physical input devices

The STM32G474E-EVAL board provides several input devices for physical human control.
•
four-way joystick controller with select key (B1)
•
wake-up/ tamper button (B2)
•
reset button (B3)
•
10 k
•
light-dependent resistor, LDR (R174)
The potentiometer and the light-dependent resistor can be routed, mutually exclusively, to
the PB11 port of the STM32G474QET6.
configuration jumpers.
As illustrated in the schematic diagrams, the PB11 port is routed, in the STM32G474QET6,
to the noninverting input of the Comp6 comparator or OpAmp4 operational amplifier.
