- Pin 1 (PB7/PB8/PB9/PC14-OSC32_IN): These are GPIO pins with multifunction capabilities including I2C, SPI, USART, and timers. PC14 is also used for the OSC32_IN function to connect an external 32.768 kHz oscillator for real-time clock (RTC) function.
- Pin 2 (VDD/VDDA): Power supply pins for digital and analog circuits on the microcontroller.
- Pin 3 (VSS/VSSA): Ground reference for digital and analog circuits.
- Pin 4 (PF2-NRST/PA0/PA1/PA2): NRST is the Not Reset pin for microcontroller. PA0, PA1, and PA2 are general-purpose I/Os which can be used for analog inputs, digital I/O, timers, etc.
- Pin 5 (PB0/PB1/PA8/PA11): General-purpose I/O pins with functionalities such as timers, external interrupts, and so forth.
- Pin 6 (PA12): General-purpose I/O pin.
- Pin 7 (PA13): Typically used for SWD (Serial Wire Debug) for programming and debugging.
- Pin 8 (PA14-BOOT0/PA15/PB5/PB6): PA14 can be used for BOOT0 function which decides the boot space after reset. Others are general-purpose I/Os with various functionalities.
Capacitors (C1, C2)- Pins 1 (P1) and 2 (P2): These are the electrical connections for the capacitor, connecting to the circuit to provide filtering, decoupling, or energy storage functionalities. The specific usage depends on the circuit design.
NPN Transistor (Q1)- Pin 1 (B): Base terminal controls the transistor's switching functionality.
- Pin 2 (E): Emitter terminal, typically connected to ground or negative voltage in an NPN transistor.
- Pin 3 (C): Collector terminal, through which the controlled current flows and is usually connected to a load.
Resistor (R1)- Pin 1 (P1) and 2 (P2): Connection points for the resistor, which provides a specific amount of resistance in the circuit, used for biasing, filtering, or setting current levels.
AMS1117-3.3 (U2)- Pin 1 (GND): Ground terminal for the voltage regulator.
- Pin 2 (VOUT): Regulated output voltage pin, supplying 3.3V in this case.
- Pin 3 (VIN): Input voltage pin to the regulator, where the unregulated voltage is applied.
- Pin 4 (TAB(VOUT)): Tab usually connected to the output voltage, in certain packages serves as additional heat dissipation.
Diode (D1)- Pin 1 (K, Cathode): The terminal through which the current leaves the diode.
- Pin 2 (A, Anode): The terminal through which the current enters the diode.
