The STM32L073Z-EVAL evaluation board has been designed as a complete demonstration and development platform for the STMicroelectronic’s 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.
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.
