Product Overview

TINYDUINO OVERV I E W
The TinyCircuits TinyDuino is an Arduino compatible board in an ultra compact package. Imagine the possibilities of having the full
power of an Arduino Uno in a size less than a quarter!

The TinyDuino Platform is a miniature open-source electronics platform based on the easy-to-use hardware and software Arduino
platform. The platform is comprised of a TinyDuino processor board and multiple TinyShields which add special functions, like
sensors, communications and display options. By stacking the boards (plugging them together), you create a TinyDuino Stack for
your particular project.
The TinyDuino Processor Board is basically the Arduino Uno board shrunk down to the size of a quarter. It uses the same Atmel
Atmega328P microcontroller as used on the Uno, and supports all of the same shield signals - 14 digital input/output pins (of which
6 can be used as PWM outputs) and 6 analog inputs, which can be accessed by several different Breakout TinyShields (also
called Proto Boards). The one functional difference between the TinyDuino Processor Board and the Arduino Uno is that the TinyDuino uses an 8MHz ceramic
resonator instead of the 16MHz that the Uno uses. There is a great reason for this - this allows the TinyDuino processor board to run down to 2.7 Volts, which enables
it to run directly off of batteries (such as Li-ion and coin cells).
MODULAR
Each module in the TinyDuino family has been optimized to include only the core circuits for it’s specific function to keep the size as low
as possible at the best possible price. The main TinyDuino processor board includes the core processor circuitry, however the USB and
DC power regulators have been offloaded to TinyShields. So for example, if you have a project that doesn’t need support for DC power
above 5 volts, you don’t need to include the Power TinyShield, saving you money and keep the overall size down. Or if you don’t need
USB on your project, you’d only need one USB TinyShield that you’d use to program your boards.

Just like on the standard Arduino platform, where you can add expansion shields to add more features, the TinyDuino allows expansion by using TinyShields. Whether
you want to add communication capabilities (like Bluetooth, WiFi, USB), sensor readings, drive a display or run motors for your swarm of tiny robots – there is a shield
for that. The TinyShield interface uses a low cost, very miniature connector that supports all of the signals (and a few spare) that are supported on the standard
Arduino Shield connectors. And being so compact, the board to board stackup height is only 3mm, meaning even adding a few TinyShields will still allow for an
extremely compact final product.
