1 Description
The STM32303E-EVAL evaluation board has been designed as a complete demonstration
and development platform for the ARM® cortex®-M4 core-based STM32F303VET6
microcontroller. It features two I2Cs, three SPIs, five USARTs, one CAN, four 12-bit ADCs,
two 12-bit DACs, internal 64 KByte Data SRAM, 16 KByte Program SRAM and 512 KByte
Flash, touch sensing, USB FS, JTAG debugging support. This evaluation board can be
used as the reference design for user application development but it is not considered as a
final application.
The full range of hardware features on the board can be used to evaluate all peripherals
(USB FS, USART, Audio DAC and ADC, TFT color LCD, IrDA, LDR, MicroSD card, motor
control connectors, humidity sensor, high brightness LED, CAN, IR receiver, EEPROM,
touch sensing buttons & temperature sensor, etc.) 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 an embedded in-circuit debugger and
programmer for the STM32 MCU.
The STM32303E-EVAL evaluation board does not support STM32F3x8 MCUs line (1.65 V
to 1.95 V power supply).
