- USB OTG Full Speed interface
- Flexible memory controller
Additionally, the board has:
- LCD with 24 segments
- LEDs (red and green)
- Pushbutton
- Joystick
- Audio DAC
- MEMS (Gyroscope/Accelerometer/Magnetometer)
- 128 MBit Quad SPI Flash Memory
- Embedded Ammeter to measure comsumption of the STM32L476 microcontroller
The board can be powered by one of the following
- ST_LINK V2-1
- USB FS Connector
- External 5 V
- CR2032 battery
There are two serial interface that can be used during debugging.]
- There is a serial connection between target MCU STM32L476 and the host MCU (a STM32F103CBT6).
- There is a virtual serial connection, that shares the debug connections.
The serial connection
