Barebones Arduino Circuit Kit


Assemble an Arduino-compatible circuit with all the major components required and freedom to build it on a breadboard or integrate it into your project on a custom PCB. It includes an Atmega328 IC with the Arduino Uno bootloader, a 5V and 3.3V regulator, power and status LEDs, a reset switch, and a header for external programming. Because this circuit lacks the USB converter IC, an external USB-Serial programmer is required.
