Product Description

So if you are looking at this product you probably fried your Arduino Uno. Don't feel bad, it happens to the best of us. We have taken the time to put the Uno bootloader on these bad guys, so if you need to replace or upgrade your chip it will be a snap! Of course don't forget you don't actually need an Arduino to use this chip. This is a standard ATMEGA328 AVR compatible chip.

They're cheap, buy a bunch.

What I really liked was the tutorial that let me remove the Atmega328 chip from my UNO board and then run some jumpers to program my project.

After purchasing many components from Virtuabotix, I recently had the opportunity to know this company a little better.

I purchased a couple of these ATMEGA328-PU and I was in the process of building my first Bareduino328 Plus, but the voltage regulators that I had purchased somewhere else were faulty (they overheated when connected to a 9v battery and produced virtually no output, almost zero volts). I sent an email to Virtuabotix to inquire about the best match for the voltage regulator that they used in their demos, and within minutes Joseph Dattilo (CEO of Virtuabotix) replied with a much better answer than I was expecting: he confirmed that the model I indicated should work, but also mentioned that he could make it available on their site just to help me with my project. Within minutes, they had the perfect voltage regulator available, and for an excellent price too.

It is not very common to receive courteous and effective assistance these days, but it is even less common to experience this kind of niceness and competency at once in a single person and company. To me, it is almost more important than the product itself.

BTW: To date, I have purchase the following products from Virtuabotix, and they all receive 5 stars from me. Their products are very cheap, but of excellent quality too!

Since i'm a computer programmer, my electrical skills are limited to the basic understandings of capacitors, current, resistors, ohms and amps. Thus when I perform calculations, I often fudge the math and cross my fingers. Unfortunately time after time i've busted a many Arduino. If you've been a victim of an Arduino popping and then allowing the magic vapors escape thru the crack of the ATMEGA chip, then save yourself the money and avoid SMD (surface mounted) Arduino configurations. Always setup your prototypes on a board that let's you swap out the chip. It'll cost you way less in the long run and keeps your from having to put a halt on your projects due to a damaged Arduino. The fact that these chips are also preloaded with the firmware is a blessing, as even for a skilled programmer this task can be a pain in the tucas.

Received the item promptly and popped it in my Arduino Uno to replace a malfunctioning chip. It's working great! It's a good price, so I may order some more of these in the future.

I ordered this Arduino Uno bootloader because the one I had burned out. I replaced it with this one and it works great. It even works with the previous version, Arduino Dueminalove.

Cratered my original Arduino. This pre-imaged chip is faster to boot and does everthing the Uno does. They're cheap, buy a bunch.

Worked like a charm for an interactive Art project using proximity sensors. What I really liked was the tutorial that let me remove the Atmega328 chip from my UNO board and then run some jumpers to program my project. This saved me $25, everyone else out there wants you to get one of their special FTDI boards when you already have one sitting right in front of you. Thanks Virtuabotix...!

These work great, with the boot-loader installed. No need for a special hardware programmer if you have a 28 pin Arduino Uno board, or compatible. No need for special wiring, and ISP code.

I took out the chip from the UNO, placed one of these chips in, USB worked well, installed the sketch. Took the chip out, put it in my standalone board with hand wired 16 MHz Xtal oscillator and it worked the first time. So, a servo controller for about $4 including Xtal and parts, to control 7 servos with all the analog inputs was working in minutes.

This is cheep, and runs any sketch, with any library. You do not need to spend time to write "special" code for a unique chip like the ATtiny. I plan to put a "zero insertion" socket on my UNO board just to program these. No need for special drivers, or hardware. It would make a great backup if your Arduino stops working (just put one of these ATMEGA328P-PU /w Boot-loader in, and it's fixed.

I have been programming ATtiny chips, but it's very limited, the sketches must be tailored for the tiny, and few library's work on them. I resorted to using assembly code, which takes more time, and not much code to barrow from on the net. So, if you don't need the super low power, and smaller size of the ATtinyXX series, use these ATMEGA328P-PU /w Boot-loader.

Beginners will love this!

After I got a good hang of circuitry, soldering and working with the Arduino UNO (and yes, there's still plenty to learn!), I soon realized that I would need to have the projects I create using the UNO to break away and run on their stand alone circuit board(s). So after digging around and researching a bit on how the process goes, I learned that if you can purchase the chips with the UNO bootloaders already included onto the chip, you can simply take out the chip from the Arduino after it is programmed, and then you can pop in another one (ATMEGA328P-PU with Arduino Bootloader - Uno ), program it, and you would be good to go. No need to wire up another circuit to simply write the bootloader onto the chip (which can be done and there's a ton of instructions on how to do this on the Arduino website and Google). I guess the only downside is that I ended up paying about $1.00 to $1.50 more per chip compared to if I had bought the chips blank (no bootloader). But on the other side, it was much faster of a process. I simply wrote my code, uploaded it, then opened my other sketch, took off the chip from the Arduino, replaced it with one of these chips with the boot loader, then uploaded again...... =) If you don't mind spending the extra $1.00 per piece, I highly suggest to go this route. It will save you some time and perhaps some head ache....
