Important update for the Dev Board / SoM

If you have a Coral Dev Board or Coral SoM, please install latest Mendel update as soon as possible to receive a critical fix to part of the SoC power configuration. To get it, just log onto your board and install the update as follows:

Dev Board / Som

This will install a patch from NXP for the Dev Board / SoM’s SoC, without which it’s possible the SoC will overstress and the lifetime of the device could be reduced. If you recently flashed your board with the latest system image, you might already have this fix (we also updated the flashable image today), but it never hurts to fetch all updates, as shown above.

WebCoral – Coral USB accelerator for Chrome browser

If you don’t like typing the command line in the terminal, Google has added Coral USB Accelerator support in Chrome over WebUSB. Only works on Linux and macOS for now. You’ll need to set up a web server and enter some commands to set up device rules on Linux, but when you’re done, go to http: // localhost: 8000 in Chrome and flash your USB accelerator software. Try some models, such as SSD MobileNet v2, with your own images.

 Edge TPU

New features of Edge TPU brought to ModBerry series

In October 2020, with the release of the latest Compute Module 4 from Rasbperry Pi Foundation, TECHBASE announced an upgraded device from ModBerry 500 series, called ModBerry 500 CM4. Thanks to the high-performance PCI-Express bus introduced in Compute Module 4 and Raspberry Pi community, the device itself presents support for a wide range of new applications, such as use of Google’s Artificial Intelligence modules at ease.

Therefore, TECHBASE designed a new device, called ModBerry AI GATEWAY 9500-CM4, utilizing the vertical format of ModBerry 9500, latest Compute Module 4 and Google’s Coral TPU. Installation-ready AI GATEWAY allows direct application in industrial fields.

AI GATEWAY with Coral TPU enhancement 

Neuron network capabilities enhance CM4-based devices, not only collecting and sending data, but also allows local data change predictions and allows direct management on-site. This feature gives the possibility for various applications, such as data analysing and establishing trends predictions, smart alarms and smart monitoring, local notification control, etc.

Used Edge TPU coprocessor via PCI-Express bus is capable of performing 4 trillion operations per second (TOPS), using 0.5 watts for each TOPS (2 TOPS per watt). Google Coral easily integrates with Raspberry Pi Compute Module in Linux and optionally in Windows with full support of TensorFlow Lite framework and AutoML Vision Edge solution.

AI GATEWAY with available expansion cards 

ModBerry AI GATEWAY 9500-CM4 can be equipped with serial RS-232/485 ports, range of digital and analog I/Os, USB, HDMI and Ethernet. Interfaces can be expanded with additional I/Os and opto-isolation, relays, Ethernet, 1-Wire, CAN, M-Bus Master and Slave, accelerometer, OLED screen and many more features like TPM Security Chip, eSIM and SuperCap backup power support. 

ModBerry AI GATEWAY 9500-CM4 series also offers a standard PCI module support for various wireless communication protocols, such as:

  • GSM modem (4G/LTE and fast 5G modem, interchangeable with Coral TPU)
  • economic NarrowBand-IoT technology
  • LoRa, ZigBee, Sigfox, Wireless M-Bus
  • secondary Wi-Fi/Bluetooth interface or Wi-Fi Hi-Power
  • custom wireless interfaces

ModBerry AI GATEWAY 9500-CM4 availabilityFirst prototypes are being developed, since Compute Module 4 is already available for the purchase. Delivery time for various configurations of AI GATEWAY will be approximately 2 months, depending on the CM4 supply on the market and chosen expansion cards.

ASUS Tinker Edge T - a new Raspberry Pi like SBC

ASUS announced Tinker Edge T in mid-2019, but now officially announces their latest SBC. Edge T expands Tinker Board series, which was already a strong rival of Raspberry Pi and latest Google Coral Dev Board.

The ASUS company has designed Tinker Edge T for AI applications powered with has Google Edge TPU. Google has optimized Edge TPU for machine learning and must be able to run Tinker Edge T up to 4 ter per second operations (TOPS) at just 0.5 W. Therefore, this board is a good candidate for automatic image recognition and other automation projects

Industrial use of various development boards

Introduced in November 2017, the ModBerry M300 series, based on NanoPi NEO revolutionised the economic segment of Industrial IoT devices and proved, that automation and monitoring can be done effectively with low expenditure on industrial installations.

ModBerry M300 O1 based on OrangePi Zero Plus features Allwinner H5 (Quad-core Cortex-A53) SoC, moderate 512MB RAM, storage memory option with microSD slot, USB and Gigabit Ethernet port. The wireless communication is supported with onboard Wi-Fi module.

Offering much higher performance and wider feature range, the ModBerry M300 O2 features same SoC as M300 series, but thanks to OrangePi Zero Plus2 means, the device is equipped with onboard 8GB eMMC, extra microSD expansion slot as alternative and wired/wireless interfaces, e.g. HDMI, Wi-Fi, Bluetooth 4.0.

Coral Dev Board - a new Raspberry Pi-like platform from Google

The Coral platform launched by Google is expected to contribute to the easier creation of systems in the field of the Internet of Things. During CES 2020, the manufacturer will devote a lot of attention to her.

Google presented a new, miniature accelerator module for the Coral platform. The sensor has dimensions of only 10×15 mm, so it is smaller than the American one-cent coin. Coral is a Google platform created to facilitate the construction of equipment compatible with the Internet of Things technology, equipped with artificial intelligence.

Components produced by Google have already been used to create many intelligent systems used, for example, in healthcare, agriculture or technologies supporting the functioning of cities. Coral works well also in offline mode and with limited connectivity. The new module is expected to increase its functionality.

The Coral Dev Board together with the USB and PCIe accelerator went on sale in 2019, and is now being sold in 36 countries. We can expect many innovations related to this technology during CES 2020. Google announces that it has prepared various demonstrations of the new module capabilities for this meeting.

Google’s Coral Dev Board

Coral Dev Board

Unlike popular single board, Raspberry Pi or Raspberry’s Chinese competitors, according to Google, Coral Dev Board is to be a specialized computer – it is primarily targeted at developers who want to have a device on which algorithm learning is possible. The computer is running Mendel Linux built on Debian, we will also find Tensor Flow Lite libraries with ready-to-compile models. No internet connection is required in the learning process – the entire process is done locally.

From the hardware side, the most important here is the Edge TPU coprocessor – a Google tensor system designed to be used together with the Tensor Flow library used in machine learning. In addition, the board got the ARM 4-core NXP i.MX 8M processor, GC7000 Lite Graphics, as much as 1 GB of RAM (LDPRR4) and 8 GB of eMMC memory. Coral connects to other devices via Wi-Fi oral USB Accelerator and Bluetooth 4.1.

Therefore, it cannot be said that, compared to other SBC Coral, it is hardware limited. What’s more, it has a microSD card slot, two USB type C sockets (one for power supply, the other for data transfer), minijack output, HMDI output, GPIO pins. The device can also be connected to the Internet via a cable with an RJ-45 plug. It is also possible to buy a camera useful in machine learning image processing algorithms.
