10 Hardware layout and configuration
The STM32L476 Discovery board is designed around the STM32L476VGT6 (100-pin LQFP
package). The hardware block diagram (see
Figure 2) illustrates the connection between
the STM32L476VGT6 and the peripherals (9-axis motion sensors, digital microphone
MEMS, LCD segment, 128
Mbytes of Quad-SPI Flash memory, SAI Audio DAC stereo with
3.5mm output jack, USB OTG FS, IDD current measurement, LEDs, push-button, joystick)
and the
Figure 3 will help to locate these features on the STM32L476 Discovery board.
