STM8L1526-EVAL evaluation board
Introduction
The STM8L1526-EVAL evaluation board is a complete demonstration and development
platform for STMicroelectronic's STM8 core-based STM8L152C6 microcontroller which
supports I2C, SPI, USART, 12-bit ADC, 12-bit DAC, LCD driver, 2 KB internal SRAM, 32 KB
EEPROM and SWIM debugging.
The full range of hardware features on the board helps you evaluate all peripherals (motor
control, USART, audio DAC, LCD, IR LED, IrDA, SPI Flash, MicroSD Card, temperature
sensor and EEPROM... etc.) and develop your own applications. Extension headers
facilitate easy connection of a daughterboard or wrapping board for specific applications.
An ST-LINK is integrated on the board as the embedded in-circuit debugger and
programmer for the STM8 MCU.
