The new STM32F429 discovery board key features are impressive:

  • STM32F429ZIT6 microcontroller featuring 2 MB of Flash memory, 256 KB of RAM in an LQFP144 package
  • On-board ST-LINK/V2 with selection mode switch to use the kit as a standalone
  • ST-LINK/V2 (with SWD connector for programming and debugging)
  • Board power supply: through the USB bus or from an external 3 V or 5 V supply voltage
  • 2.4″ QVGA TFT LCD
  • SDRAM 64 Mbits
  • L3GD20, ST MEMS motion sensor, 3-axis digital output gyroscope
  • Six LEDs:
    • LD1 (red/green) for USB communication
    • LD2 (red) for 3.3 V power-on
    • Two user LEDs:LD3 (green), LD4 (red)
    • Two USB OTG LEDs:LD5 (green) VBUS and LD6 (red) OC (over-current)
