Meet the ZynqBerryZero: An FPGA Development Board with a Raspberry Pi Zero Form Factor

Germany Based Trenz Electronics, has released a new FPGA development board, a 3 x 6.5cm SoC module with integrated Xilinx Zynq-7010 FPGA and a Pi Zero form factor, called the ZynqBerryZero.

The Zyncberryzero

New ZynqBerryZero, nicknamed “little cousin” to older Zynqberry, is the latest addition to the company’s Raspberry Pi inspired FPGA lineup of boards. The ZynqBerryZero is actually raspberry pi-inspired like it’s an older cousin but can be used as an FPGA alternative to the Raspberry Pi Zero.

The ZynqberryZero packs it’s processing power punch with a Xilinx Zynq-7000 FPGA and a dual Arm Cortex-A9 MPCore, physically located in the middle of the FPGA’s programmable logic.

Some features of the ZynqberryZero include:

  • Xilinx Zynq-7010 FPGA
  • 512 MB DDR3L SDRAM
  • 16 MB flash memory
  • One microSD card slot
  • Two microUSB connectors: 1x micro USB for JTAG/UART and 1x micro USB 2.0
  • 40 pin HAT header
  • Type C mini HDMI connector, and
  • CSI-2 connector.
  • Total GPIO: 26 (all provided by high-speed connectors)
  • Dimensions: 3cm x 6.5 cm
  • Operating temperature: Depends on customer design and cooling solution.

The ZynqberryZero module is currently available and sells for $149.74 (with shipping) or $129.09 (without shipping). Though the price looks like what could make the ZynqberryZero module quite the investment piece for projects, the module offers users quite a lot of features that make it totally worth it.

The power and flexibility of the FPGA’s capabilities in such a tight, well-designed layout make the ZynqberryZero a great option for a lot of projects. Having an onboard ARM processor surrounded by the programmable logic also means countless design options for the ZynqberryZero module.

The ZynqberryZero can from one of its micro USB ports instead of looking for an external power supply to use.

Displaying the versatility and compatibility features of the ZynqberryZero, Trenz in a recent demonstration showed that with a little tweak, the ZynqberryZero can be used interchangeably with a Pi Zero in projects. This is buttressed by the shared form factor which ensures compatibility with a majority of Raspberry Pi peripherals with little or no adaptation.

A reference design is not currently available for the ZynqberryZero but one can easily work out the pinout based on the available schematics and XDC generator files available on Trenz’s website.

The board is currently available on Trenz’s website for €109.00 excluding shipping. More details on the features and availability of the ZynqberryZero module can be found on the product’s sales page on Trenz’s Online Store. 

Grillo, IBM and Linux to accelerate deployment of open source earthquake early warning (EEW) detection systems

Earthquakes are shifts or vibrations in the earth’s crust caused by a sudden release of violent energy and the effects that come with them, especially with the large ones, can be devastating. The earlier citizens are warned ahead of its occurrence, the better their chances of survival.

Fair enough, a number of earthquakes early warning systems already exist, but most of these systems are typically centralized and built on expensive equipment. The good news is that Grillo, a distributed sensor expert – in partnership with Linux Foundation and global tech giant, IBM – have open-sourced an IoT-based earthquake early warning system, believed to potentially save lives in the future, called OpenEEW.

Speaking about the origin of the project, Grillo founder, Andres Meira said,

“For years we have seen that EEWs have only been possible with very significant governmental financing, due to the cost of dedicated infrastructure and development of algorithms. We expect that OpenEEW will reduce these barriers and work towards a future where everyone who lives in seismically-active areas can feel safe.”

Speaking also on the OpenEEW being

“the very best in technology and open source”, was Mike Dolan, Senior Vice President and GM of Projects at the Linux Foundation. Dolan said the Linux Foundation is “pleased to be able to host and support such an important project and community”, adding that the OpenEEW project will accelerate the creation of low cost, community-driven projects across the world.

The OpenEEW, by contrast to other EEW systems, can run on a Raspberry Pi single-board computer with a bare-minimum outlay on additional hardware. It is based on low-cost high-performance MEMS accelerometers and is equal with professional seismometers in performance but 60 times less expensive. The sensor also has WiFi and Ethernet connectivity for sending readings back to the central server, a loud buzzer, and 3x bright Neopixel LEDs for alarming. The operating voltage is 3.3V with a current of 1A (maximum).

IBM on its own part, added a new dashboard for the Grillo’s earthquake sensor to visualize sensor readings and thereafter sent out six of the sensor systems to conduct tests in Puerto Rico. The company, through it’s Chief Technology Officer of Call for Code, Daniel Krook, said it will continue to collaborate with Grillo and the Linux Foundation to bring contributions to the openEEW project.

More information on the OpenEEW project including how to deploy your own sensors, detect earthquakes and send alerts, is available on the project’s website and on the project’s GitHub repository.

Arduino empowers every user to meet the IoT security challenge

Arduino, the leading IoT product development platform, has announced it will make security best practices achievable by anyone by including them as standard in the popular, easy-to-use Arduino IoT Cloud solution. Specifically in the IoT space, operating without sophisticated security measures in place can put customers and their data at risk. Today, data, network, and device security remain the primary concern for 50% of organizations when adopting IoT. Arduino understands the risk of compromise and is constantly looking for ways to improve security in both its hardware and software, with a strong focus on “security by design”. Arduino IoT Cloud is a low-code platform that enables users to log, graph, and analyze their sensor data, trigger events, and automate their home or business.

You can sign up for Arduino IoT Cloud for free today and now automatically benefit from integrated security features including: Secure communication with Arduino Portenta H7, Arduino Nano 33 IoT and Arduino MKR family boards using their on-board secure elements (NXP EdgeLock SE050 or Microchip ATECCX08A) The open-source ArduinoBearSSL library for implementing the TLS protocol on devices A device certificate provisioning process to allow client authentication during MQTT sessions.

Fabio Violante, CEO of Arduino said:

“Our priority has always been to build solutions that ensure maximum security for our users and developers and take every step to minimize risk. We are extremely proud of the development of a model that can make our solutions secure by design. As IoT devices continue to proliferate at pace, we will remain committed to finding even more ways to improve security for years to come.”

Many of today’s embedded devices still do not properly implement the full SSL/TLS stack. Optimized for constrained devices, ArduinoBearSSL aims at producing small code footprints and low RAM usage.

It provides developers with a sturdy foundation to their codebase that is fully interoperable with existing SSL/TLS servers. Security and performance was a focus when fitting the standard Bear SSL into Arduino’s embedded IoT core. Arduino IoT enabled boards to include one or more (as in the case of the Portenta H7) hardware crypto chips dedicated to the fast computation of cryptography operations. RAM is therefore free of these demanding tasks, private keys are stored securely, and true random number generation (a basic operation to ensure secure communications) can be delivered effectively.

Different communication techniques are put in motion behind the scenes to guarantee a point to point encrypted communication between the Arduino-powered IoT device and Arduino’s servers. Both techniques, asymmetric and symmetric encryption, facilitate a handshake between the client and the server, and issuing unique session keys. The process of device registration in the Arduino IoT Cloud has been simplified to help developers optimize their workflows. Arduino’s API exposes an endpoint a client can interact with, the client requests to register a new device on the Arduino IoT Cloud, to which the server (API) returns a UUID (Universally Unique IDentifier) that will be stored in the board’s crypto element. From that moment and on, developers can use that UUID in their code to identify their devices against the Arduino IoT Cloud. The device’s private key cannot be extracted by the secure element – a fundamental benefit of installing the IoT Cloud security model on official Arduino boards.
