STM32F4-Discovery presentation
It is a card with a lot of possibilities and a small price (about $15). If we compare with the Ardruino cards, this card is much more efficient for the same price.
STM32F4-Discovery Key Features:
- STM32F407VGT6 microcontroller featuring 32-bit ARM Cortex-M4F core, 1 MB Flash, 192 KB RAM in an LQFP100 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 USB bus or from an external 5 V supply voltage
- External application power supply: 3 V and 5 V
- LIS302DL or LIS3DSH ST MEMS 3-axis accelerometer (LIS3DSH on last versions)
- MP45DT02, ST MEMS audio sensor, omni-directional digital microphone
- CS43L22, audio DAC with integrated class D speaker driver/li>
- Four user LEDs, LD3 (orange), LD4 (green), LD5 (red) and LD6 (blue)
- Two push buttons (user and reset)
- USB OTG FS with micro-AB connector to interface externes systeme (USB key, PC, …)
