Arduino Zero Hardware is Not Just for Beginners

 

We stopped by the Atmel booth at Maker Faire to gawk at the pre-production Arduino Zero boards they were showing off. [Bob] gave us a rundown of everything the new board offers, and it’s better than we imagined when we heard about it last week.

I may be an odd egg in that I don’t like to use an IDE when developing uC firmware. Generally I rock the text editor and a makefile for 8-bit, adding OpenOCD and GDB when working with ARM. I probably shouldn’t be surprised that there is already OpenOCD support (and by extension GDB support) for the Arduino Zero. In fact, that’s how the Arduino IDE flashes the board. This should have been obvious since the board is really just a breakout for the SAM D21 chip which is already supported.

Riffing on the thought of this being a breakout board, we think they did a pretty good job. There are two USB connectors; one let you access the board as a device or a host while the other connects the debugging hardware. If you’ve never used an On Chip Debugger before it’ll change your life so do give it a try. When you do move past the initial prototyping phase of your project you can still use the Zero as a debugging tool. There’s an unpopulated 10-pin header (not sure if the small pitch header comes with it or not) which can be used to interface with a target board. [Bob] also spent some time talking about the configurable 6-pin header which allows you to choose from a range of hardware protocols (SPI, TWI, etc.).

Unfortunately we still don’t have info on the availability timeframe or pricing information. There was one hiccup with this pre-production run (two signals were swapped on the PCB) and they need to spin another board, populate, and QA before they can green-light the final product.

Editorial Note: Atmel advertises on Hackaday but this video and post are not a product of that relationship. Hackaday doesn’t post paid content.

Introducing The Arduino Zero

Zero

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.
