The AVR Dragon, low cost programmer and development kit

The AVR Dragon, Atmel has set a new standard for low cost development tools. AVR Dragon supports all programming modes for the Atmel AVR device family. It also include full emulation support for devices with 32kB or less Flash memory.
At a fraction of the price traditionally associated with this kind of featured tool, the AVR Dragon will fulfill all your programming and emulation needs. The flexible and secure firmware upgrade feature allows AVR Studio to easily upgrade the AVR Dragon to support new devices.

To see which devices are currently supported please read the Device Support page.
(New devices will be added through AVR Studio updates or Service Packs on a regular basis)

Supported Protocols

Currently the following protocols are supported:

Programming Interfaces:
  • In System Programming ( ISP )
  • High Voltage Serial Programming ( HVSP )
  • Parallel Programming ( PP )
  • JTAG Programming ( JTAG Prog)

Emulation Interfaces: (Only available for devices with 32kB Flash or less)
debugWIRE ( dW )

AVR Dragon can be used with an external target board. However, the onboard prototype area, allow simple programming and debugging without any additional hardware besides strapping cables. Please see the Using the AVR Prototype Area section for a description on how to use this.

AVR Dragon is powered by the USB cable, and can also source an external target with up to 300mA (from the VCC connector, 5V) when programming or debugging. For more information on technical details, please read the AVR Dragon Requirements section. If the target is already powered by an external power source, the AVR Dragon will adapt and level convert all signals between the target and the AVR Dragon.

Note: If the target board is powered by external power source, no connection should be made betwwen the VCC connector and the external board.

AVR Dragon if fully supported by AVR Studio. This allows the AVR Dragon firmware to be easily updated to support new devices and protocols. When connecting the AVR Dragon, AVR Studio will automatically check the firmware and prompt the user if an updated firmware is available.

Motorola MC33794DWB electric field sensor

The 33794 is intended for applications where noncontact sensing of objects is desired. When connected to external electrodes, an electric field is created. The 33794 is intended for use in detecting objects in this electric field. The IC generates a low-frequency sine wave. The frequency is adjustable by using an external resistor and is optimized for 120 kHz. The sine wave has very low harmonic content to reduce harmonic interference.
The 33794 also contains support circuits for a microcontroller unit (MCU) to allow the construction of a two-chip E-field system.

Arduino Wireless SD shield

As the name implies, the Arduino Wireless SD shield serves two functions. Foremost, this shield allows you to easily interface with Xbee transceiver modules to create mesh networks, and other wireless devices. Secondly, the micro SD socket allows you to store and access a large amount of data. Whether using these functions by on their own or together, this chip greatly enhances the capabilities of a standard Arduino.

The Wireless SD shield allows an Arduino board to communicate wirelessly using a wireless module. It is based on the Xbee modules from Digi, but can use any module with the same footprint. The module can communicate up to 100 feet indoors or 300 feet outdoors (with line-of-sight). It can be used as a serial/usb replacement or you can put it into a command mode and configure it for a variety of broadcast and mesh networking options. The shields breaks out each of the Xbee's pins to a through-hole solder pad.

Included on board is a SD card slot. When using the SD Library to access the card, Pin 4 is CS and cannot be used otherwise. SPI also relies on pins 11, 12, and 13 for communication.
An on-board switch allows the wireless module to communicate with the USB-to-serial converter or with the microntroller.

The Arduino Pro

The Arduino Pro is a microcontroller board based on the ATmega168 (datasheet) or ATmega328 (datasheet). The Pro comes in both 3.3V / 8 MHz and 5V / 16 MHz versions. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a battery power jack, a power switch, a reset button, and holes for mounting a power jack, an ICSP header, and pin headers. A six pin header can be connected to an FTDI cable or Sparkfun breakout board to provide USB power and communication to the board.
The Arduino Pro is intended for semi-permanent installation in objects or exhibitions. The board comes without pre-mounted headers, allowing the use of various types of connectors or direct soldering of wires. The pin layout is compatible with Arduino shields. The 3.3V versions of the Pro can be powered with a battery.
The Arduino Pro was designed and manufactured by SparkFun Electronics.

  • Microcontroller ATmega168 or ATmega328
  • Operating Voltage 3.3V or 5V

The Arduino Leonardo

The Arduino Leonardo is a microcontroller board based on the ATmega32u4 . It has 20 digital input/output pins (of which 7 can be used as PWM outputs and 12 as analog inputs), a 16 MHz crystal oscillator, a micro USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.

The Leonardo differs from all preceding boards in that the ATmega32u4 has built-in USB communication, eliminating the need for a secondary processor. This allows the Leonardo to appear to a connected computer as a mouse and keyboard, in addition to a virtual (CDC) serial / COM port. It also has other implications for the behavior of the board; these are detailed on the getting started page.

Arduino Uno - R3 origin Italy

The new Arduino Uno R3. 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.  Online Order

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.

Arduino is an open-source physical computing platform based on a simple i/o board and a development environment that implements the Processing/Wiring language. Arduino 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 Arduino Uno R3 requires the Arduino 1.0 drivers folder 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!   Onlline Order

MAX195 16-Bit, 85ksps ADC with 10µA Shutdown

The MAX195 is a 16-bit successive-approximation analog-to-digital converter (ADC) that combines high speed, high accuracy, low power consumption, and a 10µA shutdown mode. Internal calibration circuitry corrects linearity and offset errors to maintain the full rated performance over the operating temperature range without external adjustments.

CM02/400 - Radio Communications Module

The CM02 module, together with its companion RF04 module, form a complete interface between your PC and our range of I2C modules. You can send commands down to your robot and receive telemetry data back up to the PC. Now you have all the modules necessary to control your robot from your PC. The CM02 is powered from your robots battery, which can be anything from 6v to 12v. The CM02 can monitor battery voltage and report this back to the PC (so your robot knows when its hungry!). There are four I2C connectors on the CM02, but your not limited to four I2C devices. In practice, you may only need one connector and route the I2C bus around all the modules you wish. Bit rate on the I2C bus is approximately 100KHz.
