I'd give six starsAt this price, I always keep a few in stock.

Excellent product at a rock bottom priceI just bought two of these and after burning the bootloader they both work perfectly well. I' ll buy some more to make barebones arduinos and spare my development boards.
As far as burning the bootloader is concerned, I found out that the instructions found in :
http://www.gammon.com.au/forum/?id=11637
are the best for doing the job on a breadboard, with just a 16.000 Mz crystall (also from Tayda), a couple of capacitors and a resistor.
Thank you Tayda once more !

Great for breadboarding and embeddingAdd a 16 MHz crystal and two capacitors to the ATMEGA328P-PU and you have the heart of an Arduino Uno that's perfect for breadboarding. All that's required is to upload the Ardiono bootloader, and you're done. There are good tutorials on the web.
Suggestions: buy a good USB to TTL converter, either a cable or a small add-on board. Be sure the converter outputs the RTS (Request to Send) signal for easy uploading. Avoid the $7, 4 terminal cheapies. They are more trouble than they are worth.
Buy a bunch of 1K and 10K resistors and .1 microfarad ceramic disk decoupling capacitors, and if you want to interface the Ardiono to the Real World or a Raspberry Pi, buy lots of optoisolators, too. While you are at it, pick up some of the great breadboards from this site. The price and value simply cannot be beat.
Once you have your USB breakout cable, any USB charger can power the chip.

Had it up and running in no timeI had no trouble using my Arduino Uno R3 as isp to burn the bootloader on the chip. With other parts from here (16mhz crytal, caps, voltage regulator) I was able to have it mounted on a breadboard perfectly.
Much better than buying another arduino.Posted on

100% Working with Arduino UNO R3I burn optiboot using Arduino Uno as ISP. You can burn optiboot bootloader by using just 16000 hz crystal. What you'll need to put 16000 hz crystal between pin 9 and 10. Then load ArduinoISP sketch then upload, and then load optiboot sketch (select Arduino as ISP menu) then burn Bootloader.
I've tested that 18-22 pf Capacitor (2x), 120ohm, and 10Kohm resistor is not needed (can be omitted).

Great!I must agree with the many great reviews this product has gotten. I have not put this chip to use yet, other than testing it out and seeing how it performed on a breadboard. Was able to get it working without the arduino bootloader within a couple minutes. Good product, will be buying more! Can't beat the price of only $3.50.
Keep up the good work Tayda!Posted on

Recomended!!!Price: Great!!! Best price I have found any where
Quality: Great I have uploaded the optiboot arduino boot loader to all 4 I got and they're all working great and I'm using them for I2C, Serial, SPI, LCD and a few other things and they are working wonderfullyPosted on

PerfectPerfect condition. I use these for tons of projects. I like how it came inside foam to protect the pins. Keep it up Tayda
