New Arduino microcontroller boards


Image: arduino.cc The Arduino team has presented at the Maker Faire Fair in New York, new models of its open-source prototyping microcontroller series. Major innovation in the Arduino is due in mega-format, which is equipped with a blog, according to Arduino Atmel SAM3U, an ARM Cortex-M3 processor with 96 MHz, 256 KB Flash and 50 KB SRAM stately. The processor's I / O side features five SPI, two I2C serial ports and five. Its 16 analog inputs have a resolution of 12 bits. Which of the pins will be passed out on the new Arduino board is not yet clear. Due to the Arduino therefore includes the significant performance gap with other boards in the Arduino format, such as the very young and Digilent chipKit from Microchip, the MIPS-based PIC32 processor with a 80 MHz contains.

Even the little Arduino developers have improved: The new Arduino Leonardo is a 16-MHz Atmel Atmega32U4 equipped 2.5 Kbytes of SRAM and 32 Kbytes of Flash, which takes over the USB communication with the host. In a separate Atmega8U2 Uno done this task, one on older boards FTDI. Leonardo-The circuit is thus cheaper and the programming of USB LUFA clients via USB library is much simpler. The adjustments for the expected Atmega32U4 the Arduino open SDK for other boards with the processor, such as the 2.0 Teensy and the breakout of Adafruit.

Another innovation in the Arduino Zoo is a WiFi-Shield, which is according to the manufacturer as a single on the market only open source components. An AVR32 processor should take care as coprocessor to the TCP / IP stack. The new components are available are still not fixed yet and the prices. A limited pilot production of the Arduino due to be distributed in the coming days store.arduino.cc to developers.
