2pcs ARM STM8S103F3P6 STM8 Minimum System Development Board Module For Arduino STM8S Core Board Module LED Indicator 5V 3.3V STM8S's core board: Using the development board of the MicroUSB cable, compatible with smart phone lines, the data line is simple and easy, but without the USB mini cable power supply, the USB mini-cable is not easy to find and has gradually been phased out.Manufacturers of other products are also being used for small usb ports, which are not applicable to customers. Low price, user-friendly design, a complete set of data, let you save money, save time, energy, worry! Main features of STM8S: 1.Use STM8S103F3P6 as the main IC. 2.You can use 2.54 pins on the board or on the power board. When using the power supply, the input voltage range is 4.5v-15v, which can be exported to the outside of the needle 3.3 v! Note: the voltage of 5V needle is the input voltage of the module. 3.All the pins, the pins next to the pin mark the label, there's a reset button, the power guide, this program demonstrates the LED, although it's small but perfect. 4.Supports debugging mode to swim. Technical information: 1.The core board structure chart (PDF format) and test source code.Burned in the test program, LED flash, which allows you to detect the work of the core plate. 2.Both the IAR and STVD development environment register operations and library functions are provided.Timing procedures, UART transmission routines, UART reception routines, clock switching routines, AD routines, etc. 3.STM8 application. 4.STM8 package library. 5.IAR development environment, STVP programming software. Performance comparison of STM8S103F3P6 performance: The STM8S003F3 chip only has 128 bytes of EEPROM, STM8S103F3 640 bytes; STM8S003F3 chip is only cleaned 100 times, STM8S103F3 can be erased 10,000 times. The STM8S103F2 chip only supports 4K byte and STM8S103F3 has 8K bytes. Conclusion: STM8S003F3 is only suitable for mature products. STM8S003F3 core plate is not suitable for development.However, STM8S103F3 is used for development and our development board USES the chip.
