STM32 Arm | Black Pill

Features: 

 The main chip STM8S105K4T6 core board is pre-programmed with each test module. After power-on, the LED light will flash evenly and check whether the development board works normally. 

 Medium density program and data storage: - Up to 32K bytes of Flash; data can be saved for 20 years at 55˚C after 10K erasing - Data memory: up to 1K bytes of real data EEPROM; up to 300,000 erases

 RAM: up to 2K bytes

 3.0~5.5V working voltage

 Flexible clock control, 4 main clock sources - Low power crystal oscillator - External clock input - User adjustable internal 16MHz RC - Internal low power 128kHz RC

 Clock security system with clock monitoring. 

 Power management: - Low power mode (waiting, active shutdown, shutdown) - The peripheral's clock can be turned off separately 

 Interrupt management: - Nested interrupt controller with 32 interrupts - 6 external interrupt vectors, up to 37 external interrupts 

 Timer: - 2 Channel 16 -bit general purpose timer with 2 + 3 CAPCOM channels (IC ,OC or PWM) - Advanced control timer: 16 bits 4 CAPCOM channels, 3 complementary outputs, dead-time insertion and flexible synchronization - With 8-bit prescaler, 8-bit basic timer - Automatic wake-up timer - 2 watchdog timers: window watchdogs and independent watchdogs 

 Communication interface: - UART with synchronous clock output, smart card, infrared IrDA, LIN interface - SPI interface up to 8Mbit/s - I 2 C interface up to 400Kbit/s analog-to-digital converter (ADC) - 10 bit, ± 1LSB of the ADC, up to 10 channels, scan mode and analog watchdog feature 

 I/O Port: - 48 pin package up to 38 I/Os on the chip, including 16 high-sink current outputs - Very strong I/O design, the reverse current has a very strong capacity 

 Development support: - Single-line interface module (SWIM) and debug module (DM) for easy online programming and nonintrusive debugging
