ATMEGA328P-PU PDIP-28 Microchip Technology Microcontroller

The ATmega328P is the microcontroller of the Arduino UNO, here in the PDIP-28 through-hole package. It can be programmed with an Arduino UNO as a programmer or with an ISP programmer and then used on a custom circuit board. The component still carries the Atmel name; the company is now part of Microchip.

Recommended Accessories:

• USBasp AVR Programmer USB ISP with Adapter Plug
• Arduino Uno Rev3

Features:

• 8-bit AVR microcontroller in a PDIP-28 package
• Programming via ISP, also with an Arduino as ISP; an Arduino bootloader can be installed the same way
