STM32L152-EVAL evaluation board
Introduction
The STM32L152-EVAL evaluation board is a complete demonstration and development
platform for STMicroelectronics’ ARM cortex-M3 core-based STM32L152VBT6
microcontroller supporting two I2C, two SPI and three USART channels, 12-bit ADC, 12-bit
DAC, 16 KB internal SRAM and 128 KB Flash, USB FS, LCD controller, touch sensing and
JTAG debugging support.
The full range of hardware features on the board helps you evaluate all peripherals (USB
FS, USART, Audio DAC, microphone ADC, dot-matrix LCD, LCD glass, IrDA, light
dependant resistor (LDR), MicroSD Card
TM
and temperature sensor amongst others) and
develop your own applications. Extension headers make it possible to easily connect a
daughter board or wrapping board for your specific application.
An ST-LINK/V2 is integrated on the board as embedded in-circuit debugger and
programmer for the STM32 MCU.
