STM8S103F3P Micro USB Development Board

Product Features
This development board is powered via Micro USB and is compatible with Android phone USB data cables, making it convenient to power and use. It offers an affordable price, user-friendly design, and complete documentation to save you time, effort, and cost.

Uses the STM8S103F3P as the main microcontroller.
Can be powered through the 2.54 mm header pins or the Micro USB connector.
When powered through the USB connector, the input voltage range is 4.5–15V.
The board also provides a 3.3V output via the header pins.

Note: The 5V header pin is directly connected to the input power supply.
All MCU pins are broken out and clearly labeled. Includes:
*Reset button
*Power indicator LED
*User/Test LED
*Supports SWIM programming and debugging.
