: A 16 MHz crystal oscillator connected to the XTAL1 and XTAL2 pins, usually accompanied by two 22pF ceramic capacitors to GND.
: A 10kΩ pull-up resistor connected from the RESET pin to VCC to prevent accidental resets, often paired with a tactile push button to GND for manual resetting. Atmega Development Board Schematic
: Breakout pins that provide access to all digital and analog pins for interfacing with external components like LEDs or sensors.

An ATmega development board schematic typically includes the microcontroller (MCU), a power regulation stage, a clock source, and headers for programming and general-purpose I/O (GPIO). The most common design is based on the (the heart of the Arduino Uno). Core Schematic Components a power regulation stage
