XOLCANO STM32,BLE & GSM DEVELOPMENT BOARD

5,000.00Rs. 4,600.00Rs.

The Blue Pill is a 32-bit Arduino compatible development board that features the STM32F103C8T6, a member of the STM32 family of ARM Cortex-M3 core microcontrollers. This board aims to bring the 32-bit ARM Cortex microcontrollers to the hobbyist market with the Arduino style form factor.

Powering your Blue Pill:

There are three ways of powering your Blue Pill development board:

  • Using the built-in USB micro connector(ONLY if you are not Using GSM).
  • Supplying 5V to the 5V pin as external supply(ONLY if you are not Using GSM).
  • Supplying 12V 2A directly to the DC JACK.

Input/Output:

The Blue Pill has 37 GPIO pins spread across four ports – A and B (16 pins), C (3 pins) and D (2 pins). Each pin has a current sink/source ability of 6mA. Pull-up and pull-down resistors can be enabled on each of the pins.

Most pins have extra functionality as well:

  • Serial ports – receive and transmit data via the UART protocol
  • I2C ports – two-wire communication via the IIC protocol
  • SPI – serial communication
  • PWM
  • Pin 13 has a built-in LED

These special functions and their respective pins are illustrated in the Blue Pill pin diagram shown above.

How to Use the STM32 Development Board?

The Blue Pill can be programmed in two ways–

  • Using an external USB/Serial converter connected to UART1 pins, which is the default bootloader for this family of boards. It can be programmed using the Arduino software this way.
  • STLink USB Dongle – this uses the single-wire debug interface to communicate with the board. This allows it to be programmed using advanced software like Keil/CubeMX. It also allows memory access using the STLink software.

Before programming, it is important to connect the BOOT0 jumper to 1 and press the reset button to put the chip in ‘programming mode’.

Uploading Your First Program

If programming using the Arduino software, the appropriate board files should be downloaded using preferences and boards manager.

Then the correct board must be selected on the board’s menu.

Since the built-in LED is on pin 13, just like the Arduino, the basic blink sketch will work on the Blue Pill.
