STM32L073Z-EVAL Evaluation board

Overview

The STM32L073Z-EVAL Evaluation board is designed as a complete demonstration and development platform for the STMicroelectronics Arm® Cortex®-M0+ 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 192-Kbyte flash memory, 20-Kbyte RAM, 6-Kbyte EEPROM, touch sensing, USB FS, LCD controller, SWD debugging support. This Evaluation board can be used as a reference design for user application development but is not considered as a final application.

The full range of hardware features on the board helps the user to evaluate all peripherals (USB FS, RS-232, USART, 12-bit ADC and DAC, color TFT LCD, LCD segments, low-power UART, IrDA, microSD™ card, touch-sensing slider, pressure measurement, temperature measurement, LC sensor metering) and to develop applications. The extension headers offer the possibility to connect a daughterboard or a wrapping board for a specific application.

An embedded ST-LINK/V2-1 debugger facilitates the software development and the programming of the STM32L073VZT6 microcontroller.
