_ Six 5 V power supply options:
Power jack
ST-LINK/V2 USB connector
User USB HS connector
User USB FS1 connector
User USB FS2 connector
Daughterboard
_ SAI Audio DAC, stereo audio jack which supports headset with
microphone
_ Stereo digital microphone, audio terminal connector used to connect
external speakers
_ 2 GBytes (or more) SDIO interface MicroSD card
_ RF EEPROM on I2 C compatible serial interface
_ RS-232 communication
_ IrDA transceiver
_ JTAG/SWD and ETM trace debug support, ST-LINK/V2 embedded
_ IEEE-802.3-2002 compliant Ethernet connector
_ Camera module
_ 8M x 32-bit SDRAM, 1M x 16-bit SRAM and 8M x 16-bit NOR Flash
_ Joystick with 4-directional control and selector
_ Reset, Wakeup and Tamper buttons
_ 4 color user LEDs
_ Extension connectors & memory connectors for daughterboard or
wrapping board
_ USB OTG HS and FS with Micro-AB connectors
_ RTC with backup battery
