“Most powerful” Arduino ever has ARM Cortex-A8 chip, runs “full Linux”

The Arduino TRE.

The Arduino line of open source electronic prototyping platforms is getting some major upgrades. Earlier today, the first Intel-powered Arduino was announced, and it will be available by the end of November.

Arduino has also announced the Arduino TRE, based on the Texas Instruments Sitara AM335x ARM Cortex-A8 processor. Texas Instruments said that with the TRE’s 1GHz processor, it is the “most powerful Arduino to date” and the first that will be able to run “full Linux.” It will be available in spring 2014 from and other distributors, with pricing not yet announced.

“For the first time ever, Arduino users can use the full capabilities of Linux and gain access to a variety of new on-board connectivity options to develop a range of powerful, advanced applications while leveraging the simplicity of the Arduino software experience,” the Texas Instruments announcement said. “The Sitara-processor-powered Arduino TRE serves as a network hub that can connect to millions of classic Arduino nodes, enabling customers to be at the forefront of the Internet-of-Things era.”

Your robot army, controlled by Arduino and Bluetooth

The RFduino “maker” allows hardware hackers to build devices with Arduino code and Bluetooth wireless communications.

Soon, you could make everything in your life smartphone-app-controllable—or at least the things that have wires. A California-based inventor has taken to Kickstarter to fund the launch of the latest evolution in “maker” technology—an Arduino-compatible microcontroller that’s small, fast, and cheap, with built-in wireless communications. The RFduino has already exceeded its Kickstarter goal nearly 30 times over, with 10 days to go before its deadline.

Based on a Nordic Semiconductor 32-bit ARM system-on-chip that has built-in support for Bluetooth 4.0, the RFduino runs the same code as Arduino UNO and DUE boards, and it works with any type of sensor, servo, or other device that can communicate with an Arduino microcontroller. Bluetooth 4.0’s Bluetooth Low Energy (BLE) feature allows the microcontroller to run on power sources as small as a button-cell battery for some applications—and the team has developed a “shield” for the CR2032 battery, as well as single- and dual-AAA battery configurations. It can also run off a USB power source or can be wired directly to a 3-volt DC power source.

As a result, the RFduino could be used for a whole host of devices that interact with mobile devices, including remote controls, proximity-switch devices such as alarms, and home automation applications that control LED lighting. It could also allow devices programmed with Arduino “sketches” to interact with each other over Bluetooth 4.0—potentially allowing for the development of swarms of smart devices that can talk both to smartphones and notebook computers and their environments.
