STM32F051C8T6 development board

Overview

Open051C is an STM32 development board that features an STM32F051C8T6 device as the microcontroller. There are further expansions with various optional accessory boards for specific application. The modular and open design makes it the ideal for starting application development with STM32F family.


What's On Board

STM32F051C8T6 development board on board resource

  2. AMS1117-3.3: 3.3V voltage regulator
  3. Power switch
  4. Power indicator
  5. LEDs: for indicating I/O status
  6. Reset button
  7. User key: for I/O input and/or interact with running code
  8. Joystick: for I/O input (five positions)
  9. 32.768K crystal oscillator: used for internal RTC, also supports clock calibration
  10. 8M crystal oscillator: enables the MCU run at 48M frequency by frequency multiplication
  11. 8I/Os + DAC + ADC Interface: easily connects to keypad, motor, etc.
  12. SPI1 / SPI2 interface
  • easily connects to SPI peripherals such as FLASH (AT45DBxx), SD card, MP3, etc.
  • convenient for connecting AD module, thanks to the SPI1 alternative AD function
I2C1 / I2C2 interface: easily connects to I2C peripherals such as I/O expander (PCF8574), EEPROM (AT24Cxx), etc. LCD interface: easily connects to the touch screen LCD ONE-WIRE interface: easily connects to ONE-WIRE devices (TO-92 package), such as temperature sensor (DS18B20), electronic registration number (DS2401), etc. USART1 interface: easily connects to RS232, RS485, USB TO 232 USART2 interface: easily connects to RS232, RS485, USB TO 232 I2S / I2C1 interface: easily connects to I2S peripherals such as audio module, etc. PS/2 interface: for connecting PS/2 keyboard/mouse. 5V DC jack 5V/3.3 V power input/output, usually used for power output, or common ground with other user board MCU pins connector: all the MCU pins are accessible on expansion connectors for further expansion SWD interface: for debugging/programming Boot mode selection: for configuring the BOOT0 pins LEDs jumper
  • short the jumper to connect the LEDs to I/Os used in example code
