This will allow you to use Arduino code in your custom embedded project without having to use an actual Arduino board.

The name says it all on this one. An ATmega328 in DIP package, pre-loaded with the Arduino Optiboot (Uno 16MHz) Bootloader. This will allow you to use Arduino code in your custom embedded project without having to use an actual Arduino board.

To get this chip working with Arduino IDE, you will need an external 16MHz crystal or resonator, a 5V supply, and a serial connection. If you are not comfortable doing this, we recommend purchasing the Arduino Uno board that has all of these built into the board.

Atmel’s ATMega328 8-Bit Processor in 28 pin DIP package. It’s like the ATmega168, with double the flash space. 32K of program space. 23 I/O lines, 6 of which are channels for the 10-bit ADC. Runs up to 20MHz with external crystal. Package can be programmed in circuit. 1.8V to 5V operating voltage!

Note: This contains the bootloader used on the Arduino Uno, with small modifications to work more reliably with different serial connection options (mainly the FTDI). Check the link below for more information.

Perfectly fit
Color: Crystal Clear
I recently purchased a Mac Neo protective case, and it has exceeded my expectations. The case fits my laptop perfectly, with precise cutouts that ensure all ports are easily accessible and well-aligned. I especially appreciate the crystal-clear design, which maintains the original look of the device while providing solid protection. The included keyboard cover is a great bonus—it feels comfortable to type on and doesn’t interfere with responsiveness. Overall, the case combines functionality, protection, and aesthetics very well.

Love this little thing. Totally worth every penny!
Color: White, Color: White
I love this little powerhouse label maker. Totally worth the value and ease of use and functionality. Also I love that I can easily change text size and font very simply while using. I have used it so many times already and I often make a label for something just because it’s easy and fun and makes things feel very organized. Helped me be very organized in my kids homeschool room, with art supplies, my storage drawer cart and my filing cabinet. Definitely worth buying and it comes with a good amount of labels. I’ve purchased another roll since buying it but I’ve labeled a ton of things. Simple, easy to do on your phone and the labels turn out perfect, clear, concise and even.

Perfect for Organization and Super Efficient
Color: White
I got this label maker because I am going to be a teacher and needed an easy way to label and organize a lot of materials, and it has been perfect for that. It is very quick and efficient, and I was able to start using it right away without any issues. The labels come out clear, and the whole process is simple and convenient, especially when you have a lot to get done. I also really like how compact and easy to use it is, which makes it great for both classroom and home organization. Pros: • Very fast and efficient • Easy to set up and use • Great for organizing classroom materials • Compact and convenient • Great value for the price Overall: This is a great tool if you need to label and organize quickly. I would definitely recommend it, especially for teachers or anyone who likes to stay organized.

Works wonderfully, I'm obsessed with labeling!
Color: Green
This is super easy to set up and use. I love the color and the size. I didn't want a label maker that needed a whole drawer to live in. The print is great, I love the multiple font options. My only complaint is that the label paper cutter on this actually cuts it too short. So when you go to print the next label it believes there is no paper. For the price point, I'd say absolutely worth the purchase
