Printoo is a modular platform specifically designed for printed electronics components. At its core is a high performance, low power 8-bit AVR ATMega328 microcontroller. Below is a list of the various modules and components that make part of Printoo. Pictures are of Printoo in prototyping stages, the final product may still have slight alterations.



Printoo Core Module

Printoo-core (2)
Microcontroller: Atmel ATmega328
Operating Voltage: 1.8 – 5.5 V
Flash Memory: 32 kB
SRAM: 2 kB
EEPROM: 1 kB
Clock Speed: 16 MHz

For the full technical specifications, please consult the microcontroller datasheet.

Physical Characteristics

Printoo board has approximately 35 mm x 35 mm (1.38 inch x 1.38 inch) in length and width, and has less than 2 mm (0.08 inch) of thickness. The board itself weighs 4 g.

Programming

Printoo is fully compatible and programmable with the Arduino IDE (download). The ATmega328 microcontroller on the Printoo board comes pre-burned with a bootloader that allows you to upload new code into it with the Arduino IDE.
