The STM32L073Z-EVAL Evaluation Board has been designed as a complete demonstration and development platform for the STMicroelectronics ARM Cortex-M4 STM32L073VZT6 microcontroller. Included are three I²C, two SPI, four USART, UART, 12-bit ADC, two 12-bit DAC, LCD driver, up to 192 KB Flash memory, 20 KB RAM, 6 KB EEPROM, touch sensing, USB FS (Full Speed), LCD controller, and SWD debugging support. The full range of hardware features on the board can be used to evaluate all peripherals and offer an incentive to develop applications.
An ST-LINK/V2-1 is integrated on the board as embedded in-circuit debugger, programmer for the STM32 MCU and USB Virtual Com Port bridge.
