Development Board Schematic: Atmega

: A 16 MHz crystal oscillator connected to the XTAL1 and XTAL2 pins, usually accompanied by two 22pF ceramic capacitors to GND.

: An ICSP (In-Circuit Serial Programming) header consisting of MISO, MOSI, SCK, RESET, VCC, and GND for flashing firmware using an external programmer. Atmega Development Board Schematic

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 16 MHz crystal oscillator connected to

: Breakout pins that provide access to all digital and analog pins for interfacing with external components like LEDs or sensors.
