Microcontroller minimum circuit in PCB Design - Dashboard Guide

Dashboard Mode - Microcontroller minimum circuit

Goal

Understand the essential components and connections needed for a microcontroller minimum circuit to function properly.

Sample Data: Components and Connections

Component	Type	Value/Specification	Connection
Microcontroller	IC	ATmega328P	Power, Ground, Reset, Clock
Power Supply	DC Voltage	5V regulated	VCC pin
Ground	Reference	0V	GND pin
Reset Button	Switch	Momentary push-button	Connected to RESET pin and GND (pull-up resistor to VCC)
Pull-up Resistor	Resistor	10kΩ	Between RESET pin and VCC
Decoupling Capacitor	Capacitor	0.1µF	Between VCC and GND near MCU
Crystal Oscillator	Oscillator	16 MHz	Connected to XTAL1 and XTAL2 pins
Load Capacitors	Capacitors	22pF each	Between crystal pins and GND

Dashboard Components

• KPI Card: Total Components - shows count of components used (8)
• Table: Components and their connections - displays the sample data table
• Bar Chart: Component Types Count - counts how many components of each type (IC:1, Resistor:1, Capacitor:2, Switch:1, Oscillator:1, DC Voltage:1, Reference:1)
• Diagram: Simplified circuit block diagram - visual showing microcontroller connected to power, ground, reset circuit, and clock circuit

Interactivity

User can filter components by type using a dropdown filter. Selecting a component type updates the table and bar chart to show only that type. The KPI card updates the count accordingly. The diagram highlights the selected component's connection block.

Self Check

If you add a filter to show only 'Capacitor' components, which dashboard components update and how?

• The KPI Card updates to show total components: 2
• The Table shows only capacitor components (Decoupling Capacitor and Load Capacitors)
• The Bar Chart updates to show only Capacitor count: 2
• The Diagram highlights the capacitor blocks connected to power and crystal oscillator

Key Result

Dashboard shows essential components and connections for a microcontroller minimum circuit with interactive filtering by component type.
