CuteUino: Only Use The Parts Of The Arduino That You Need For Each Project

CuteUino

[Fran’s] been working on her own version of the Arduino. She calls it CuteUino for obvious reasons. The size of the thing is pretty remarkable, fitting within the outline of an SD card. But that doesn’t mean you won’t get the power that you’re used to with the device. She’s broken it up into several modules so you can choose only the components that you need for the project.

The main board is shown on the right, both top and bottom. It sports the ATmega328p (it’s hard to believe we could make out the label on the chip package in the clip after the break) in a TQFP-32 package soldered to the underside of what she calls the Brain Module. You can also see the extra long pins which stick through from the female pin headers mounted on the top side of the board. Inside of these pin headers you’ll find the clock crystal, status LEDs, and a capacitor. The other module is an FTDI board used to connect the AVR chip to a USB port.

You’ll definitely want to check out her prototyping post for this project. She uses a very interesting technique of combining two single-sided boards to make a 3-layer PCB. The side that was not copper clad is fitted with copper foil by hand to act as a ground plane for the vias. Neat!
