NEW PRODUCT – Arduino Due (ok, coming soon – they should be here shortly!)… Put your Arduino project on TURBO mode with the high-speed, high-power Arduino Due! The Due cranks it up to 11 with an 84 MHz ARM core processor – 512K of FLASH storage! 96K of RAM! Both USB client and host! The Arduino Due is ideal for those who want to build projects that require high computing power. For example, remotely-controlled drones that, in order to fly, need to process a lot of sensor data per second – or an audio player that uses the built in Digital-to-Analog converter (Arduino.cc page).
The Arduino Due also gives students the opportunity to learn the inner workings of the ARM processor in a cheaper and much simpler way than before.
To scientific projects, which need to acquire data quickly and accurately, Arduino Due provides a platform to create open source tools that are much more advanced than those available now.
The new platform enables the open source digital fabrication community (3d Printers, Laser cutters, CNC milling machines) to achieve higher resolutions and faster speed with fewer components than in the past.
Main features of Arduino Due
The board is equipped with a SAM3X8E processor from Atmel (datasheet), based on the 32 bit ARM Cortex M3 architecture running at 84MHz.
USB 2.0 interface running at 480 Megabits that allows Arduino Due to act as a USB Host (so you can interface it to USB devices like mice, keyboards, cameras, mobile phones and more). Arduino Due supports the Android ADK 2012 protocol.
12 analog inputs (ADC) with 12-bit resolution and high speed, opening the door to audio applications and signal processing projects that were impossible with Arduino Uno.
High-resolution Analog outputs (DAC). The board provides two 12-bit outputs that can be used to generate audio signals. The Arduino Due software comes with software examples for a WAV and OGG player.
4 high-speed serial communication ports.
70 input/output pins.
High-speed CAN interface. The CAN protocol is used in the automotive industry to network the different components of the car, is now becoming popular in the field of industrial automation thanks to its speed and ability to withstand electrical noise.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

will there be a compatibility list for the adafruit shields? I am mostly interested in the lovely motor shield. There is a big warning on the arduino.cc page on the 3.3 Volt max on the pins compared to the arduino Uno family.
The board sells in Germany for 46 Euro (including 19% VAT)
If your shield can work with 3.3v, then it should be fine. If they shield requires 5v, there is going to be a problem.
Either the sheild will not get the signal it requires and not function as expected, or worse, it will try to feed 5V back to the due and that could damage it (they are very clear, 3.3v is the limit).
Personally, I think they are blowing what makes the arduino such a popular tool – the standardization of the shields. They should have a different standard footprint for 3.3v boards.
It looks like it should be possible to create a 5v to 3.3v signal level adapter shield using things like the TXB0108 and BSS138 for digital signals. The 74LVC245 appears to be too limited, but its page suggests op amps for analog.
I’m not an engineer, so perhaps one could chime in and either confirm the possibility or blow me outa the water here? Thanks.
