crystal provides much improved (+/-0.005%) accuracy in comparison to the lower (+/-0.5%) accuracy of the standard Arduino's ceramic resonator for 100X improvement in real time measurement accuracy

Description

AVR.duino is our version of the popular open source Arduino Uno (Rev3). The AVR.duino is completely compatible with the Arduino software development environment. Simply select Arduino Uno Rev3 when using this board with the Arduino software running on your computer. We've added extra features to this popular platform. We have included a Button, LED, and Trimmer and a BLT connector on-board to allow you to quickly test digital input (Button), digital output (LED), and analog input (Trimmer). To make real time clock timing more accurate we use a more accurate crystal oscillator in place of the low cost ceramic resonator used on the standard Arduino Uno. The surface mount AtMega328 on this board has 2 extra Analog inputs which are available for use. A SlicBus connector allows you to connect to and control SlicBus modules. This is a great educational tool and a great product development platform. If you are new to developing with microcontrollers, this is an easy way to get started. Using the Arduino environment steps you into programming easily, and handles most of the microcontroller setup and configuration details for you. Lower cost since we manufacture it and sell it to you directly.
