  • Arduino also providing Portenta Carrier board that will add extra capabilities to your H7 board

    1578338065-portentacarrier-1.jpg

    The Portenta Carrier exposes all of the extra capabilities of the processor on your microcontroller board through connectors and peripherals that do not physically fit on it. There are connectors for USB, RJ-45, CAN bus, audio in and out lines, camera, DisplayPort, etc.

    This design expands the default communication ports of Portenta boards to other wired and wireless protocols. Gigabit Ethernet will let you transform your board into a dedicated access point, a network drive, or even a serial-to-ethernet bridge. Adding a SIM card to the board makes it possible to connect to NBIoT or GPRS networks. Thanks to its LoRa connectivity you can design your own gateway to host your wireless sensor network.

    Adding an 8-bit camera sensor to the Portenta Carrier camera connector will help you implement any kind of computer vision application. And if the onboard computing power is not enough, you could enhance your board’s AI capabilities by adding state-of-the-art Machine Learning modules through the Carrier’s miniPCI connector (like Google’s Coral unit of computation).

  • Designed for demanding industrial applications, AI edge processing and robotics, it features a new standard for open high-density interconnect to support advanced peripherals. The first member of the family is the Arduino Portenta H7 module – a dual-core Arm Cortex-M7 and Cortex-M4 operating at 480MHz and 240MHz, respectively, with industrial temperature range (-40 to 85°C) components. The Portenta H7 is capable of running Arduino code, Python and JavaScript, making it accessible to an even broader audience of developers.

    The new Arduino Portenta H7 is now available for pre-order on the Arduino online store, with an estimated delivery date of late February 2020.

    Overview:

    Portenta H7 simultaneously runs high level code along with real time tasks. The design includes two processors that can run tasks in parallel. For example, is possible to execute Arduino compiled code along with MicroPython one, and have both cores to communicate with one another. The Portenta functionality is two-fold, it can either be running like any other embedded microcontroller board, or as the main processor of an embedded computer. Use the Portenta Carrier board to transform your H7 into an eNUC computer and expose all of the H7 physical interfaces.

    Portenta can easily run processes created with TensorFlow Lite, you could have one of the cores computing a computer vision algorithm on the fly, while the other could be making low level operationis like controlling a motor, or acting as a user interface. Use Portenta when performance is key, among other cases, we envision it to be part of:

    High-end industrial machinery Laboratory equipment Computer vision PLCs Industry-ready user interfaces Robotics controller Mission-critical devices Dedicated stationary computer High-speed booting computation (ms)

    Two Parallel Cores

    H7's main processor is a dual-core unit made of a Cortex M7 running at 480 MHz and a Cortex M4 running at 240 MHz. The two cores communicate via a Remote Procedure Call mechanism that allows calling functions on the other processor seamlessly. Both processors share all the on-chip peripherals and can run:

    Arduino sketches on top of the Arm Mbed OS Native Mbed applications MicroPython / JavaScript via an interpreter TensorFlow Lite

    Graphics Accelerator
    Probably one of the most exciting features of the Portenta H7 is the possibility of connecting an external monitor to build your own dedicated embedded computer with a user interface. This is possible thanks to the processor's on-chip GPU, the Chrom-ART Accelerator. Besides the GPU, the chip includes a dedicated JPEG encoder and decoder.

    A new standard for pinouts
    The Portenta family adds two 80 pin high density connectors at the bottom of the board. This ensures scalability for a wide range of applications by simply upgrading your Portenta board to the one suiting your needs

    On-board Connectivity
    The onboard wireless module allows to simultaneously manage WiFi and Bluetooth connectivity. The WiFi interface can be operated as an Access Point, as a Station or as a dual mode simultaneous AP/STA and can handle up to 65 Mbps transfer rate. Bluetooth interface supports Bluetooth Classic and BLE. It is also possible to expose a series of different wired interfaces like UART, SPI, Ethernet, or I2C, both through some of the MKR styled connectors, or through the new Arduino industrial 80 pin connector pair.

    USB-C Multipurpose Connector
    The board's programming connector is a USB-C port that can also be used to power the board, as a USB Hub, to connect a DisplayPort monitor, or to deliver power to OTG connected devices.

    Multiple options in one board
    Order the default Arduino Portenta H7 (codename H7-15EUNWAD) that comes with:

    2MB SDRAM 16MB NOR Flash 10/100 Ethernet Phy USB HS NXP SE050C2 Crypto WiFi/BT Module Ceramic Antenna DisplayPort over USB-C

    If you need more memory, Portenta H7 can host up to 64 MByte of SDRAM, and 128 MByte of QSPI Flash. Order it with an external UFL connector for adding a higher-gain antenna to the board. Decide between crypo-chips from Microchip and NXP. The board is highly customizable in volumes.

  • Woow awesome article...I have a little query here. I have found recently that we can stream Audio using ESP32 over BLE. So, in this article, it is told that the individual streaming of audio is possible. Which means do they have two BLE's in two ear pods working collaboratively when used for both ears and working individually when streamed individually?

  • Building on 20 years of innovation, LE Audio will not only enhance the performance of Bluetooth audio but will bring all its benefits to people with hearing loss and introduce Audio Sharing, an innovative new use case with the potential to once again change the way we connect with each other and experience the world around us.

    LE Audio is on Bluetooth Low Energy

    alt text

    As the names suggest, Classic Audio operates on the Bluetooth Classic radio while LE Audio operates on the Bluetooth Low Energy radio. LE Audio will not only support development of the same audio products and use cases as Classic Audio, it will introduce exciting new features that promise to improve their performance as well as enable the creation of new products and use cases.

    LE Audio is LC3

    LE Audio will include a new high-quality, low-power audio codec, the Low Complexity Communications Codec (LC3). Providing high quality even at low data rates, LC3 will bring tremendous flexibility to developers, allowing them to make better design tradeoffs between key product attributes such as audio quality and power consumption.

    LE Audio is Multi-Stream

    Multi-Stream Audio will enable the transmission of multiple, independent, synchronized audio streams between an audio source device, such as a smartphone, and one or more audio sink devices.

    LE Audio is Bluetooth Hearing Aids

    Building on its low power, high quality and multi-stream capabilities, LE Audio adds support for Hearing Aids. Bluetooth audio has brought significant benefits to a large percentage of the global population. Wireless calling, listening, and watching have made people safer, more productive, and more entertained. LE Audio will enable the development of Bluetooth hearing aids that bring all the benefits of Bluetooth audio to the growing number of people with hearing loss.

    LE Audio is Broadcast

    LE Audio will also add Broadcast Audio, enabling an audio source device to broadcast one or more audio streams to an unlimited number of audio sink devices. Broadcast Audio opens significant new opportunities for innovation, including the enablement of a new Bluetooth use case, Audio Sharing.

    Broadcast is Audio Sharing

    Bluetooth Audio Sharing can be personal or location-based. With personal audio sharing, people will be able to share their Bluetooth audio experience with others around them; for example, sharing music from a smartphone with family and friends. With location-based audio sharing, public venues such as airports, bars, gyms, cinemas, and conference centres can now share Bluetooth audio that augments the visitor experience.
