DESCRIPTION The TinyCircuits TinyDuino is an Arduino compatible board in an ultra compact package. The TinyDuino processor board is roughly equivalent to the Arduino Uno board – same processor, same signals brought out to a shield connector. In fact, most Arduino sketches will work as is without any changes. To program this board, you need to use the USB TinyShield Adapter Board. The TinyDuino Processor Board is available in three variations: With Lithium Battery Support - has an on-board Lithium battery charger that will charge the battery when attached to USB With coin cell battery support - for low power applications, use a simple CR1632 coin cell battery that can be easily changed Without battery options - the lightest and lowest cost option Main Features: Atmega328P processor (same as is used on the Arduino Uno) Power Switch Status LED 8MHz ceramic resonator External power supported with a 0.1″ power connection holes Supports automatic switching between +5V and VBATT (if +5V is present, it will be used instead of the battery) To learn more about the TinyDuino Platform, click here TECH SPECS Arduino Compatible Expandable with Stackable TinyShield Boards Optional battery connector for CR1612-CR1632 coin cell batteries Optional Lithium battery connector and charger 0.1″ spaced solder holes for external power source Robust Gold Finish – makes soldering easy and is non-corrosive Ultra compact size and weight (smaller than a US Quarter!) 20mm x 20mm (.787 inches x .787 inches) Max Height (without battery holder): 2.9mm (0.12 inches) Max Height (with coin cell battery holder): 6.58mm (0.26 inches) Ultra-thin 0.61mm (0.024 inches) PCB Weight: 1.10 grams (0.039 ounces) - Lithium version Atmel ATmega328P Microcontroller 32KB Flash, 2KB RAM, 1KB EEPROM 1.2mA (typical) @ 3V, 4MHz Default Clock speed: 8MHz 2.7V – 5.5V operating voltage 20 I/Os (14 Digital, 6 Analog / Digital I/O) – All the signals on the Arduino Shield connectors are supported! Arduino Bootloader preprogrammed (uses approx 0.5 KBytes of Flash Memory) NOTES If you are brand new to the TinyDuino, buying a kit is the best way to go since it will have all the parts needed. Check out the TinyDuino Kits here All batteries are sold separately To program this board, you need to use the USB TinyShield Adapter Board, which is sold separately. This board does not include a voltage regulator – do not supply more than +5.5V to VBATT or the +5V signal or you will permanently damage the board and ruin your day.
