ATMega328P Development Minimal Business Card

This is a simple and "cool" Arduino- compatible business card.

This is meant for geeky people!

Just a bit about it:

Mostly through hole components. There's a 1206 LED, but that's easy to solder, with a special hand-solder footprint for it.

It's extremely minimal.

I've attached a BOM:

I'm not sure if it was added correctly, so here is a quick rundown.

3 0.1UF ceramic capacitors

2 22pF capacitors

10K resistor

220ohm resistor

28 Pin DIP

Red(or any other single- color 1206 LED)

THT 16MHz crystal

Atmega 8, 168, 328- it's compatible with all 3 chips.

That's it.

(The atmega has to be programmed with Optiboot however)

Want to program it?

Solder on a 1x6 right angle male header strip to the FTDI port.

You can also solder on headers for the Arduino Uno form factor pins. If you want it to be shield compatible, solder on vertical female headers. If you want a lower profile(not really possible with that 328P DIP), you can solder on right angle ones.

This board works out-of-box with Arduino IDE, as an UNO, but requires a FTDI adapter, since it does not have a built in USB bridge such as a FTDI chip, the Atmega 8/16u2, CH340, or a CP201x.

The PCB is white, there seems to be wasted space on the left, but no! That's where you can write, (or print the silkscreen) for your name, phone number, etc. You can even expose the pads, to make it even prettier.

This is also a good gift to give at conventions.

Additionally, here's some sample images.
