The STM320518-EVAL is a comprehensive evaluation platform designed by STMicroelectronics for the STM32F051x8 microcontrollers, which belong to the STM32F0 Series. This series is known for its ARM Cortex-M0 core, combining high performance, real-time capabilities, digital signal processing, and low-power, low-voltage operation, making it ideal for a wide range of applications.

This evaluation board is a versatile tool that allows developers to explore all the features of the STM32F051x8 microcontrollers. It includes an embedded ST-LINK/V2 for programming and debugging, as well as a range of hardware features that enable the user to fully evaluate the capabilities of the microcontroller.

Key Features:

• STM32F051R8T6 microcontroller with 64 KB of Flash memory and 8 KB of RAM in an LQFP64 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
• LCD with 24 segments x 4 commons
• Four LEDs: LD1 (red/green) for USB communication, LD2 (red) for 3.3 V power on, two user LEDs: LD3 (green), LD4 (blue)
• Two push-buttons (user and reset)
• LIS302DL or LIS3DSH ST MEMS 3-axis accelerometer
• MP45DT02 ST MEMS audio sensor omni-directional 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), LD6 (blue) and two USB OTG LEDs LD7 (green) VBus and LD8 (red) over-current
• Two push-buttons: USER and RESET

With its rich set of peripherals, the STM320518-EVAL is ideal for evaluating the integrated features of the STM32F051x8 and developing applications such as motor drives, printers, 3D printers, alarm systems, video intercoms, HVAC, and smart energy equipment.
