The 328 Board

Introduction

The 328 board is a bare bones breakout board for the ATMEGA328P. Nearly all of the IO has been broken out to standard 0.1" spaced through holes, which also fits nicely into one of the slots of the Platform Board The native AVR programming header and standard 6 pin right angle header to allow for an Arduino Compatible experience.

Parts

It is up to you to order the parts. The list can be downloaded **HERE**. This can be directly uploaded into Digikey if you'd like.

Assembly

Here is what the board looks like when assembled - the only missing components here are the 9 pin headers and the x6 pin AVR programming header

And here's a video showing how I actually hand assembled this board:

Solder Paste: SMD291SNL10 (I keep mine refrigerated when not in use, then sit out for an hour or so before I need it)

Programming

If you want to be able to program the ATMEGA 328 from the Arduino IDE, then you'll need to first load the boot loader. My preferred method is to use Nick Gammon's sketch running on another Arduino:

 A big thanks to Nick Gammon for putting this together:  http://www.gammon.com.au/bootloader
 The git hub link is here:
 https://github.com/nickgammon/arduino_sketches
 Click the Download Zip button, then pull out the Atmega Programmer folder and drop that right into your Sketches folder"
 Another way to do it:

Note - from the board selection, if you're running at 16MHz, then select Arduino Mini, 328 processor. Then you're all set to use the USB-Serial Converter with the 328 board:
