Arduino Project Board




About: My name is Randy and I am a Community Manager in these here parts. In a previous life I had founded and run the Instructables Design Studio (RIP) @ Autodesk's Pier 9 Technology Center. I'm also the author ...

The Arduino Project Board is basically a board to transer your ATMEGA168/328 to when you have completed your project and no longer need to use the Arduino as a development board. Simply transfer the programmed chip from the Arduino board to the Arduino project board and you are in business. Now your Arduino is no longer tied up in your finished project and you have a simple breakout board to work with independently of the Arduino.

Here are some basic instructions for assembling it and getting started.

Step 1: Go Get Stuff:

The complete Arduino Project Board Kit includes:

(x1) Arduino Project Board PCB (or you can make your own with ProjectBoard.pcb)
(x1) Bootloaded ATMEGA328 chip
(x1) 28-pin socket
(x1) 16 mhz crystal
(x2) 22pF capacitors
(x1) 0.1uF, 25V capacitor
(x1) 10uF - 47uF, 25V capacitor
(x1) 1K, 1/4 watt resistor
(x1) tactile switch
(x1) 7805 regulator
(x1) 9V battery clip

Step 2: Resistor

Solder the 1K resistor to R1 on the board.

Don't forget to clip away the excess leads from the back side of the board.

Step 3: 0.1uF Capacitor

Solder the 0.1uF capacitor to C4.

Step 4: 22pF Capacitors

Solder the 22pF capacitors to C1 and C2 on the board.

Step 5: Switch It Up

Line up the switch with SW1. Then press it down until it "pops" in and becomes flush with the board.

Solder it in place.

Step 6: Crystal

Place the crystal atop XTL and solder it in place.

Step 7: Socket to Me

Put the socket atop the spot for the Arduino. Make certain that the notch cut into the end of the socket is located next to the 1K resistor.

Solder all 28 pins in place.

Step 8: Electrolytic Capacitor

Solder the electrolytic capacitor in the spot labeled C3.

Don't forget to make sure the "-" stripe on the capacitor is opposite from the + label on the board.

Step 9: Regulate

Add the LM7805 voltage regulator to the board in the spot labeled 7805.

The metal plate on the back of the regulator should be on the side opposite of the capacitors.

Step 10: 9V Connector

Solder the red wire from the 9V connector to the terminal on the board labeled 9V. Solder the black wire to the terminals labeled GND.

Step 11: Test LED (optional)

I added a test LED to the board of this example to demonstrate it is working.

I suggest that you don't do this if you don't have to and only add the parts you need for your project.

Anyhow... in this example the LED is connected to Pin 12 (Digital Pin 6) and then to ground through a 220 ohm resistor.

Step 12: Program and Transfer

Program your chip and transfer it to the board.

Here is the blink code for the LED example shown in Step 11:

Step 13: Power!

Plug in a 9V battery and it should be good to go.

Step 14: Use

Once it is built, programmed and powered up, the rest is kind of up to you.

This one blinks. However, you can make it do whatever you want.

Step 15: Pins

Take note of the graphic of the labeled board pin diagram. This shows exactly where each of the Arduino pins are.

Note: pin 7 - pin 10 have no breakouts on the board. To compensate for the power terminals on pins 7 and 8 not being pulled out, 3 extra power and 3 extra ground pads have been included to the right of the Arduino.

    thats a very noisy circuit why are we limited to basics?

    Will Serial Communication i.e. Tx and Rx pins be working with this please?

    hi ifim going to do this, i would also like to know where to get extra chips for arduino uno

    I found about this instructable at the following kit's description/details on another webpage. Might as well return the favor, so here it is, all for $9.99 + shipping without the chip (and $11.99 with the chip):

    It's out of stock, but these are Atmega328 chips loaded with the Arduino Uno bootloader

    Your pin designations are off by one probably caused by the omission of AREF on pin 21 which puts AVCC on pin 20. D8 as shown should be D9 etc. This is an old post so I'm sure you caught this already but I'm looking to replicate this board and it wasn't quite right for my ATmege328P. Am I missing something? Wouldn't be the first time here :)

    D8 actually wraps around to the opposite side. I had some problem with pin placement and shifted things about a bit. There is not clear pin to pin alignment.

    Thank you for the clarification. Do you know anyone who is making a PCB like this for purchase? I don't have the ability to make my own board and the only one I did find was $5 US, which is almost the cost of all the components to be installed on it.

    Yeah, and the write-up doesn't even mention what application opens a ".pcb" file, even if the uploaded ProjectBoard.pcb file were valid. It could be any of half-a-dozen freeware design programs, none of which are compatible. I tried PCB Designer in Ubuntu Linux. It didn't puke, but it also didn't display a layout.

    also can anybody tell me if this is a double layer board or single layer??
    i am new to all this and i am going to order pcb from a manufacturing company!!


    6 years ago on Introduction

    can anybody give me the size of this board
    and if anybody doesnt mind making a gerber file or a eagle CAM
    file and uploading
    thanks in advance

    When I don't feel like making my own boards I have had very good experience with this seller on e-bay. One can buy boards as a kit or just the boards.


    Reply 6 years ago on Introduction

    does this work exactly like the board above???
    if not wat are the differences????
    thanks in advance

    Hey, can anyone tell me how I can add a USB (or any other in-put method) to this board or make a separate bootloader "pc to chip".
    I'd really appreciate the help, and thanks in advance!
