UM1018 User Manual 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 TM dependant resistor (LDR), MicroSD Card 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. Figure 1.
