New Arduino: USB hardware in the controller, ARM-architecture and WiFi

At Habré (and not only) the direction to the Arduino is rather strange - in comments there are a lot of polar opinions, from “I want”, “cool”, “ordered myself”, to “bare ATMega - the same but cheaper”, “suitable only for LED blinks "and" for the same money, you can buy a full-fledged 32-bit ARM. " And it is more strange that no one mentioned new pieces of iron, which will ( or will not ) be of interest to the authors of both polar opinions.

So, to the point. At MakerFaire 2011, the development team announced new products:

- Arduino Leonardo . Budget board on an inexpensive ATMega32u4 controller (8 bit AVR architecture, 2.5kB SRAM, 1kB EEPROM, 32kB flash), which has a USB2.0 port, through which the interaction with the user's computer is realized. Due to the lack of additional interface chips (UNO used a second controller, ATMega8u2) it is circuitry simpler than Arduino UNO
')
- Arduino Due . The first Arduino, where it was decided to replace the 8-bit AVR platform. Although Atmel was not abandoned, it uses SAM3U4E , a real 32-bit Cortex-M3 ARM, which operates at 96 MHz and has 256kB flash, 50kB SRAM, and a bunch of I / O ports (5 SPI buses, 2 I2C interfaces, 5 UART, 16 analog inputs). The development of the board and software is not completed, some of the boards will be transferred to the "early developers", and soon the sale of the board version for developers will begin.

- New Arduino WiFi Shield . To expand the ability to work with the network on the shield, a separate AVR32 processor is planned, which will provide the interface to interact with the Arduino board.

The UNO and Mega boards were updated a little, now they are rev.3, they added several pins: TWI (???), Shield autoconfigure pin and, as was said at the presentation “secret pin” (in fact, it is not connected anywhere, it will be used in the next releases ). Also added a few protective diodes.

Oh yeah ... the development environment has grown to version 1.0;)

Also on the slide shown, the Arduino Robot System robot platform is shown, I didn’t find anything right away, share information in the comments.

The Arduino Robot System , indicated on the slide and not mentioned above, is a two-wheeled platform codenamed Lottie Lemon . The system is designed in conjunction with a 17-year-old guy, a champion of RoboCup from the Complubot robotics team. The system consists of two independent microcontrollers that can be programmed separately - one controller in the “base” to control the movement using the wheels and the second in the removable top board to interact with sensors and output systems. The Arduino team hopes that the system will appear in January 2012 at a price below $ 100. It seems to me that for such a price the small robot (including two Arduino) is quite attractive. A video on the topic found on Engadget .

As it seemed to me, the developers of the platform rested on the same limitations, and subsequent decisions would be complicated for compatibility with the previous boards and shields.

And finally, a video of the presentation by Massimo Banzi (Massimo Banzi), where he talks about new products (in English, 15 minutes):



PS: and for Android developers, there is an Arduino ADK board (Android Developer Kit), a Mega board option with an additional USB port, positioned for external Android devices (starting from 3.0) and available for € 59
