This is low cost development board for the new STM32L series of ultra low power microcontrollers of ST Microelectronics. STM32-H152 covers STM32L152VBT6. This board was carefully designed to low power handheld operation, with Li-ion battery charges on board and USB it's perfect to make data loggers. The 32khz crystal allow RTC implementation.
MCU: STM32L152VBT6 ARM 32 bit CORTEX M3™ with 128K Bytes Program Flash, 16K Bytes RAM, USB, LCD, I2C, SPI, USART, 32 Mhz clock, 80 GPIO, 1.8-3.6V power supply
standard JTAG connector with ARM 2x10 pin layout for programming/debugging with ARM-JTAG
