Feature: 1. Power Supply: The development board is powered by Micro USB and is compatible with for Android smart phone data cables. 2. Easy Control: Using STM8S103F3P6 as the the main control IC, also enables easy connection with 12C, IRDA, LIN, SPI, UART. 3. Simple Using: You can use the 2.54 row of pins or the pad on the board to take power. When using the pad to take power, the input voltage range is 4.5V‑15V, and 3.3V can be output to the outside through the pin at the same time. 5V row The pin is connected to the input power of the module. 4. Practical Use: Leads out all the pins, and marks the pin label, with a reset button, power indicator, and program demonstration indicator. 5. Debugging Mode: Supporting SWIM debugging mode, also supports undervoltage detection, POR, PWM, WDT, very useful. Specification: Item Type: Development Board Core Size: 8bit Speed: 16MHz Connection: 12C, IRDA, LIN, SPI, UART, US ART.
