STM32L073Z-EVAL
Overview
The STM32L073Z-EVAL is a complete evaluation and development platform for the STM32L073VZ microcontroller, featuring an ARM Cortex-M0+ core. This board is designed to demonstrate the ultra-low-power capabilities of the STM32L0 series while providing a rich set of hardware features for rapid prototyping. It includes an integrated ST-LINK/V2-1 for debugging, various power supply options, and multiple user interfaces including a color LCD and a touch sensing slider.
Why Choose This Part
This evaluation board provides a comprehensive ecosystem including a 2.8 inch color LCD-TFT with resistive touchscreen and a separate 40x8 segment LCD glass to test different display architectures. Engineers benefit from the onboard current consumption measurement circuit, which allows for real-time profiling of low-power firmware. The inclusion of diverse interfaces like RF-EEPROM, USB FS, and touch sensing enables testing of complex system-on-chip features without external breadboarding.
Applications
Key Specifications
Getting Started
To begin development, connect the board to a PC via the USB ST-LINK port to power the system and access the integrated debugger. Use the STM32CubeL0 MCU Package for drivers and middleware, and develop firmware using IDEs such as STM32CubeIDE, Keil MDK-ARM, or IAR Embedded Workbench. Review the included pressure sensor and touch slider examples in the firmware package to understand the peripheral integration.
