Description

The ATmega328P-PU provides programmable processing, digital control and analog measurement for embedded electronics projects. Its AVR architecture combines program memory, working memory and nonvolatile data storage in a compact through-hole IC.

Built-in peripherals include a USART, SPI, a Two-Wire interface compatible with I²C, timers and a six-channel 10-bit ADC. These interfaces support connections to suitable sensors, displays and other peripheral devices.

The DIP-28 package can be used with compatible IC sockets, breadboards and custom PCBs. This product is supplied as a microcontroller IC; supporting circuitry and a programming interface are required.

Bootloader status must be confirmed with the supplier. Advertise an Arduino bootloader only if your supplied stock has been programmed and verified.
