Evaluation board with STM32L073VZ MCU

The STM32L073Z-EVAL evaluation board has been designed as a complete demonstration and development platform for the STMicroelectronic’s ARM® cortex®-M4 core-based STM32L073VZT6 microcontroller with three I2Cs, two SPIs, four USARTs, one UART, one 12-bit ADC, two 12-bit DACs, LCD driver, up to 192KB Flash memory, 20KB RAM, 6KB EEPROM, touch sensing, USB FS, LCD controller, SWD debugging support.

The full range of hardware features on the board can be used to evaluate all peripherals (USB FS, RS-232, USART, 12-bit ADC and DAC, color LCD-TFT, LCD glass, Low-power UART, IrDA, MicroSD card, touch sensing slider, pressure measurement, temperature measurement, LC sensor metering) and develop user’s applications. The extension headers make it possible to easily connect a daughter board or a wrapping board specific application.

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.
