Description Overview This is the new ACMArduino Uno R3, fully compatible with arduino. In addition to all the features of the previous board, the Uno now uses an ATmega16U2 instead of the 8U2 found on the Uno (or the FTDI found on previous generations). This allows for faster transfer rates and more memory. No drivers needed for Linux or Mac (inf file for Windows is needed and included in the Arduino IDE), and the ability to have the Uno show up as a keyboard, mouse, joystick, etc. The Uno R3 also adds SDA and SCL pins next to the AREF. In addition, there are two new pins placed near the RESET pin. One is the IOREF that allow the shields to adapt to the voltage provided from the board. The other is a not connected and is reserved for future purposes. The Uno R3 works with all existing shields but can adapt to new shields which use these additional pins. ACMArduino is an open-source physical computing platform based on a simple i/o board and a development environment that implements the Processing/Wiring Language [see - link below]. ACMArduino can be used to develop stand-alone interactive objects or can be connected to software on your computer (e.g. Flash, Processing, MaxMSP). The open-source IDE can be downloaded for free (currently for Mac OS X, Windows, and Linux). Note: The ACMArduino Uno R3 requires the Arduino 1.0 drivers folder [see - Arduino IDE Download link below] in order to install properly on some computers. We have tested and confirmed that the R3 can be programmed in older versions of the IDE. However, the first time using the R3 on a new computer, you will need to have Arduino 1.0 installed on that machine. If you are interested in reading more about the changes to the IDE, check out the official Arduino 1.0 Release notes [see - Arduino Software Release Notes link below] Features ATmega328 Microcontroller Input Voltage: 7~12V 14 Digital I/O Pins (6 PWM outputs) 6 Analog Inputs 32k Flash Memory 16Mhz Clock Speed More Products View More Products

Features:   This tiny breakout board features the ADMP401 MEMs microphone. One of the key advantages to this breakout and microphone is the bottom ported input. This means the microphone's input can fit flush against the enclosure of your project. Plus you will not have to deal with trying to solder the microphone's wacky footprint. The amplifier on the breakout has a gain of 67 and more than meets the bandwidth requirements of the mic. The amplifier's AUD output will float at one half Vcc when no sound is being picked up. The amplifier produces a peak-to-peak output of about 200mV when the microphone is held at arms length and is being talked into at normal conversational volume levels. So the AUD output can easily be connected to the ADC of a micro.   Specification:   -3dB roll off at 100Hz and 15kHz 1.5 to 3.3VDC supply voltage Should comfortably output 40mW SNR of -62dBA   Package includes:   1 x ADMP401 Microphone Breakout Module with pins

Feature: The module has 12 push buttons. You can make usual keypuds for enter numbers, symbols, or navigate and selections in the program. There are pull-up resistors of different values for each button. This makes it possible to connect all the 12 keys to taking only one analog port of the microcontroller. The button consists of two parts: a cap, which can be applied to any character, and a transparent cover which can prevent blurring of the text and add light. Connection: After connecting power to the module and pressing at least one key contact at "OUT" will stress the appropriate level. Conformity stresses the buttons pressed, you can find out how on the board and in the table below (values are valid out when powered from 5v). Package includes: 1 x Button Keypad 3x4 module
