STM32F4DISCOVERY is evaluation board with 32 bit ARM microcontroller and I’m surprised what features it can offer for around 15 USD.
Main 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 STLINK/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, ST MEMS motion sensor, 3-axis digital output accelerometer (±2g/±8g with programmable triggers)
■ MP45DT02, ST MEMS audio sensor, omnidirectional digital microphone
■ CS43L22, audio DAC with integrated class D speaker driver
■ Eight LEDs:
– LD1 (red/green) for USB communication
– LD2 (red) for 3.3 V power on
– Four user LEDs, LD3 (orange), LD4 (green), LD5 (red) and LD6 (blue)
– 2 USB OTG LEDs LD7 (green) VBus and LD8 (red) over-current
■ Two push buttons (user and reset)
■ USB OTG FS with micro-AB connector (for connecting mouses, keyboards, USB flash drives)
■ Extension header for all LQFP100 I/Os for quick connection to prototyping board and easy probing
■ Hardware debugging (limited On-board ST-LINK) via USB
Description:
The STM32F4DISCOVERY helps you to discover the STM32F4 high-performance features and to develop your applications easily. It includes everything required for beginners and experienced users to get started quickly. Based on the STM32F407VGT6, it includes an ST-LINK/V2 embedded debug tool, two ST MEMS, digital accelerometer and digital microphone, one audio DAC with integrated class D speaker driver, LEDs and push buttons and an USB OTG micro-AB connector. A large number of free ready-to-run application firmware examples are available on www.st.com/stm32f4-discovery to support quick evaluation and development.
With this development kit comes only board, no manuals, no software, no USB cables. Manuals and code examples can be found on the STMicroelectronics web site . Over 20 code examples are prepared for these development environments:
- Altium, TASKING™ VX-Toolset
- Atollic, TrueSTUDIO
- IAR, EWARM (used by me)
- Keil™, MDK-ARM
