MikroElektronika Mikromedia for STM32F4 development board. This is
|
||||
another board support by NuttX that uses the same STM32F407VGT6 MCU
|
||||
as does the STM32F4-Discovery board. This board, however, has very
|
||||
different on-board peripherals than does the STM32F4-Discovery:
|
||||
|
||||
- TFT display with touch panel,
|
||||
- VS1053 stereo audio codec with headphone jack,
|
||||
- SD card slot,
|
||||
- Serial FLASH memory,
|
||||
- USB OTG FS with micro-AB connector, and
|
||||
- Battery connect and batter charger circuit.
|
||||
|
||||
See the http://www.mikroe.com/mikromedia/stm32-m4/ for more information
|
||||
about this board.

STMicro STM32F4Discovery development board featuring the STM32F407VGT6
|
||||
MCU. The STM32F407VGT6 is a 168MHz Cortex-M4 operation with 1Mbit Flash
|
||||
memory and 128kbytes. The board features:
|
||||
|
||||
- On-board ST-LINK/V2 for programming and debugging,
|
||||
- LIS302DL, ST MEMS motion sensor, 3-axis digital output accelerometer,
|
||||
- MP45DT02, ST MEMS audio sensor, omni-directional digital microphone,
|
||||
- CS43L22, audio DAC with integrated class D speaker driver,
|
||||
- Eight LEDs and two push-buttons,
|
||||
- USB OTG FS with micro-AB connector, and
|
||||
- Easy access to most MCU pins.
