Limitations

CAN operation is exclusive with LCD glass module operation.
2.13.2

Operating voltage

The supply voltage for STM32L476G-EVAL CAN operation must be within the range from
3.0 V to 3.6 V.

Extension connectors CN6 and CN7

The CN6 and CN7 headers complement the LCD glass module daughterboard connector, to
give access to all GPIOs of the STM32L476ZGT6 microcontroller. In addition to GPIOs, the
following signals and power supply lines are also routed on CN6 or CN7:
• GND
• +3V3
•
DSV
•
RESET#
•
VDD
•
Clock terminals PC14-OSC32_IN, PC15-OSC32_OUT, PH0-OSC_IN, PH1-OSC_OUT
Each header has two rows of 20 pins, with 1.27 mm pitch and 2.54 mm row spacing. For
extension modules, SAMTEC RSM-120-02-L-D-xxx and SMS-120-x-x-D can be
recommended as SMD and through-hole receptacles, respectively (x is a wild card).

LCD glass module daughterboard

The MB979 daughterboard delivered in the STM32L476G-EVAL package bears a
segmented LCD glass module. The daughterboard inserts into CN11 and CN14 extension
headers of the main board, each having two rows of pins. The corresponding female
