Our STM8 Development Board is a minimal system based on STM8S103F3P6, with 8kB Program Memory (Flash), 1kB RAM, and 640Byte EEPROM.
STM8S103F3P6 contains 1 x 8bit and 2 x 16bit timer, 16 I/Os, thereof 5 analog inputs 10bit, 1 x SPI, 1 x I2C, 1 x UART.
The MCU can be operated in a range of 2.95 to 5.5V, but the development board is designed for 3.3V.
The typical current drawn at 16MHz (run mode) is <4mA, in power down mode just 0.08mA.
The dimension is just tiny 28x17x5mm.
The pin configuration of this little development board is 13 general purpose digital I/O and 3 analog inputs.
Attention: The “+ and -” connection is straight connected to the “5V” rail. This means, you will have 5V on the “5V” rail only when you connect a 5V power supply, like for example USB port or USB charge. If you connect a higher voltage (up to 15V) to “+ and -“, you will see the same voltage on the USB port and also on the “5V” rail.
Be careful, and don’t have the development board connected to for example a 9V battery or 12V power supply, when you connect it the same time to an USB port!!
