Product Details

ATmega328 microcontroller with Arduino Uno Bootloader

The ATmega328 with a pre-loaded Arduino Uno bootloader is great for your more customised designs where you'd like to add Arduino Uno code without buying the Uno board. To enable the bootloader to function exactly like an Uno board you will need a 16 MHz crystal oscillator or resonator, a 5 V power supply and a serial connection.

Features & Benefits of the Uno Bootloader
•32 K program space
•23 I/O lines
•Runs up to 20 MHz
•1.8 V to 5 V operating voltage

Great replacement
Bought a couple hoping they would be a direct replacement for the chip on my uno and they are. Every character matches on the markings on the chip. When I received the chip, I put it straight on to the uno and uploaded a sketch. I then took the chip off and added it to my circuit. It has the bootloader already on it so everything went perfectly! Shall definitely be buying more of these!
