Also note that Atmel specifies the internal oscillator to fall with +- 10% accuracy so if you need to generate a very accurate clock signal (usually for UART transmission), an external crystal may be required.</p> Customer #403682 urn:uuid:0639132e-4e3e-d339-9e78-96342557b4e0 2013-02-18T00:35:09-07:00 <p>Hi, I know this page is pretty dead but i will still post.

I use the USBTiny programmer from Ladyada, over at Adafruit industries. Make a spot to attach a 6 pin ISP header to your board and upgrade to Arudino 1.0 for direct programming from the Arduino IDE. You can also program it through the Serial pins using a FTDI cable. All programming has to be done after you solder it to your project unless you build a programming board using POGO sticks.</p> ianlee74 urn:uuid:3a580a2e-15e6-6415-aa4b-633ab46fe08c 2011-12-30T21:13:10-07:00 <p>I have a Boarduino that uses the ATMega328 PDIP version.

If you don&rsquo;t plan on restocking, let me know so I can go elsewhere.</p> BradG urn:uuid:ac1acb0b-2d78-125a-6dcb-58f26f7801f0 2010-01-18T10:32:57-07:00 <p>Are there plans to restock this mcu? If you stock it, I will buy it.</p> tlied2 urn:uuid:be4aa835-e0ca-bc10-3519-57634af5d314 2009-07-24T23:12:52-06:00 <p>Yes, pull the ICSP pins out to a header and use an AVR programmer with the Arduino IDE to burn the firmware over ICSP.</p> tlied2 urn:uuid:982dc1c4-3044-32d1-1ac2-011420f3f5e8 2009-07-24T23:11:32-06:00 <p>A PDIP-28 version of this MCU is available as COM-09061. PDIP works well with breadboards.</p> DogNo7 urn:uuid:1577436b-dc42-17bc-9f1c-a81dbfc4bda7 2009-07-24T22:00:05-06:00 <p>Neato, but do you have a breakout board so I can use this with a solderless breadboard?</p> TwirlyWhirly555 urn:uuid:b23bc4d4-921b-6916-ae54-58d02962e435 2009-06-18T03:41:15-06:00 <p>hi<br/> As the chip does not have the arduino bootloader could it be put on the chip so it could be use with arduino<br/> Thanks</p> tlied2 urn:uuid:731dad81-2224-ed67-3c70-a96b3a804bc8 2009-06-02T23:51:37-06:00 <p>I assume you mean the Arduino bootloader, but no, this is just the raw microcontroller. You may be interested in DEV-0921 which is the ATMega328 PDIP preprogrammed with the Arduino bootloader.</p> Jonesey urn:uuid:56777950-f5c1-154f-fcd5-df92f64bb946 2009-06-02T21:25:00-06:00 <p>does this have the bootloader burnt onto it already?</p>
