STM 8 Development Board Minimum System Board STM8S003F3P6

STM8S Core Board Main Features:

• Utilizes STM8S103F3P6 as the main IC
• Can be powered using a 2.54mm pin header or solder pads
• Input voltage range: 4.5V - 15V via pads; 3.3V output available via pin
• Note: The 5V pin reflects the input voltage directly
• All pins are broken out with clear labels next to each pin
• Includes reset button, power LED, and a user demo LED
• Compact size and well-designed layout
• Supports SWIM debug mode

Technical Information:

• Includes schematic in PDF format and test code
• Preloaded test program flashes the LED to verify proper function
• Supports both IAR and STVD development environments
• Includes register and library-based examples such as:
  • Timer routine
  • UART transmit and receive
  • Clock switching
  • ADC routines
• STM8 software libraries and tools included
• IAR development IDE and STVP programming tool supported

STM8S003F3P6 Performance Notes:

• Board Dimensions: 28mm x 17mm x 5mm (1.1" x 0.66" x 0.19")
• Quantity: 1 piece

Board Features:

• SWIM Connector
• Voltage Regulator (3.3V - AMS1117)
• Micro USB connector for powering via smartphone charger or USB
• All pins accessible via headers
• Power LED indicator
• User LED connected to PB.5
• Reset switch included

Sample Code:

#include "stm8s.h"

void myDelay(void);

void myDelay() {
  int i, j;
  for (i = 0; i < 1000; i++) {
    for (j = 0; j < 100; j++);
  }
}

main() {
  GPIOB->DDR |= 0x20;       // PB.5 as Output
  GPIOB->CR1 |= 0x20;       // PB.5 as Push Pull Type Output

  while (1) {
    GPIOB->ODR |= 1 << 5;   // PB.5 = 1
    myDelay();
    GPIOB->ODR &= ~(1 << 5); // PB.5 = 0
    myDelay();
  }
}
