The Arduino Uno is the old standby of the Arduino world, with the Arduino Due picking up where the Mega left off. The Arduino Tre is a pretty cool piece of kit combining a Linux system with the Arduino pinout. Care to take a guess at what the next Arduino board will be called? The Arduino Zero, obviously.
The Arduino Zero uses an Atmel ARM Cortex-M0+ for 256kB of Flash and 32k of RAM. The board supports Atmel’s Embedded Debugger, finally giving the smaller Arduino boards debugging support.
The chip powering the Zero features six communications modules, configurable as a UART, I2C, or SPI. USB device and host are also implemented on the chip, but there’s no word in the official word if USB host will be available. There are two USB connectors on the board, though.
The Arduino folk will be demoing the Zero at the Bay Area Maker Faire this weekend. Hackaday will have boots on the ground there, so we’ll try to get a more detailed report including pricing and availability then.
