Power net portal is a special schematic object used to define a power or ground net. Power ports allow you to conveniently indicate a power net at any location in the design. Power nets of the same designator automatically connect throughout your design #portal #power
A generic fixed inductor for rapid developing circuit topology. *You can now change the footprint and 3D model at the top level anytime you want. This is the power of #generics
To connect the STM32F103C8T6 microcontroller (U1) to the 12 MHz crystal oscillator (Y1), you typically connect its pins to the oscillator pins to provide the clock for the microcontroller. Here are the steps for a typical crystal oscillator connection:
You will likely need to add external capacitors to both pins of the crystal to the ground. These capacitors typically range from 18pF to 22pF, but you should consult the crystal and microcontroller datasheets for the exact values.
Optional Resistor for Stability:
In some designs, a small resistor (around 1MΩ) is connected in parallel across the crystal to improve start-up reliability.
These connections provide the microcontroller with a stable clock source necessary for its operation. Let me know if you need further assistance with component values or other design elements!

Hi! I’m Copilot, I’m here to help you design your hardware projects. Ask me anyt...
Let's set up a basic configuration to get your STM32F103C8T6 microcontroller running. We'll include power supply connections, clock setup, and a reset circuit.
Power Supply
VDD (Pins 24, 36, 48):
Connect all VDD pins to your main power supply (+3.3V).
VSS (Pins 23, 35, 47):
Connect all VSS pins to GND.
VDDA (Pin 9) and VSSA (Pin 8):
Connect VDDA to +3.3V.
Connect VSSA to GND.
Place a decoupling capacitor (e.g., 100nF) between VDDA and VSSA.
Clock Circuitry
External Oscillator:
Connect an 8MHz crystal oscillator between PC14 (Pin 3) and PC15 (Pin 4).
Connect two capacitors (between 15-22pF) from each side of the crystal to GND.
Backup and Low Power:
Connect VBAT (Pin 1) to a backup battery or the main power supply if not using RTC.
Reset Circuit
NRST (Pin 7):
Connect a pull-up resistor (10kΩ) from NRST to +3.3V.
Optionally, connect a reset button between NRST and GND to manually reset the microcontroller.
Boot Configuration
BOOT0 (Pin 44):
Connect a pull-down resistor (10kΩ) from BOOT0 to GND to ensure the device boots from Flash.
Decoupling Capacitors
Decoupling Capacitors:
Place 100nF decoupling capacitors close to each VDD and GND pair.
Here's a summary of the connections:
Connect U1:VDD pins to +3.3V.
Connect U1:VSS pins to GND.
Connect U1:VDDA to +3.3V with a decoupling capacitor to GND.
Connect U1:VSSA to GND.
Connect a crystal oscillator between U1:PC14 and U1:PC15 with capacitors to GND.
Connect U1:VBAT to a backup source or +3.3V.
Connect a 10kΩ pull-up resistor from U1:NRST to +3.3V.
Connect a reset button between U1:NRST and GND.
Connect a 10kΩ pull-down resistor from U1:BOOT0 to GND.
Add 100nF decoupling capacitors between VDD and VSS pairs.
Let me know if you need further assistance or modifications!
