It serves as the brains of countless Arduino boards and allows you to run Arduino sketches directly on a standalone chip without an external programmer. Its wide operating voltage range and ample memory make it suitable for both simple and complex embedded projects.\u003c\/p\u003e\n\n\u003ch2\u003eKey Specifications\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003eMicrocontroller\u003c\/td\u003e\n\u003ctd\u003eATmega328P-PU\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eFlash Memory\u003c\/td\u003e\n\u003ctd\u003e32 KB (0.5 KB used by bootloader)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eSRAM\u003c\/td\u003e\n\u003ctd\u003e2 KB\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eClock Speed\u003c\/td\u003e\n\u003ctd\u003eUp to 20 MHz (typical 16 MHz for Arduino)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eOperating Voltage\u003c\/td\u003e\n\u003ctd\u003e1.8V to 5.5V (5V recommended for 16 MHz)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003ePackage\u003c\/td\u003e\n\u003ctd\u003e28-pin DIP\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eWhat You Can Build With This\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eStandalone Arduino circuit on a breadboard\u003c\/li\u003e\n  \u003cli\u003eCustom Arduino Uno-compatible development board\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"\/products\/kit-sd-card-data-logger\"\u003eData logger with SD card and sensor modules\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003eHome automation controller with relay and Wi-Fi\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThis microcontroller is fully compatible with the Arduino IDE and libraries. It can directly replace the chip on an Arduino Uno board or be used in custom PCBs. Common pairings include 16 MHz crystal oscillators, 22pF capacitors, and USB-to-serial adapters like FTDI FT232 for programming.\u003c\/p\u003e\n\n\u003ch2\u003eWiring Notes\u003c\/h2\u003e\n\u003cp\u003eFor standalone operation, connect VCC (pin 7) and AVCC (pin 20) to 5V, GND (pins 8 and 22) to ground. Place a 16 MHz crystal between pins 9 and 10 with 22pF capacitors to ground. Add a 10K pull-up resistor on RESET (pin 1). Programming is done via TX (pin 3) and RX (pin 2) using a 5V USB-to-serial converter.\u003c\/p\u003e\n\n\u003ch2\u003eWhy Buy from Compoden\u003c\/h2\u003e\n\u003cp\u003eEvery component is sourced from verified suppliers and tested for compatibility before listing.
