Low-power Alder Lake-N processors coming to Chromebooks, embedded systems

Intel Alder Lake-N processors succeeding Jasper Lake processors are likely to soon show up in Chromebooks and embedded systems with early clues about the features of the upcoming processors found in the source tree of Coreboot and the Sound Open Firmware (SOF) Project. The person or team at Coelacanth’s dream has been analyzing the commits related to Alder Lake-N and found some interesting information related to the CPU cores, GPU, media capabilities, and peripherals, plus some reference boards by the Google Chromium team. Their latest update analyzes a partial boot log in the SOF Project and so far we know that: Alder Lake-N is an Atom-only “Gracemont” processor (no hybrid variant like Alder Lake-S desktop processors) with up to 8 threads/8 cores Alder Lake-N has two 4-core clusters that share the L2 cache The new processors should come with Intel UHD Gen12 graphics just like Alder Lake-P/M mobile processors, but […]

Basler prB-IMX8MP embedded vision processing kit supports BCON for MIPI, GigE Vision, and USB3 Vision cameras

Basler prB-IMX8MP is a Linux-based, NXP i.MX 8M Plus powered embedded vision processing kit working with the company’s cameras designed for factory automation, medicine, traffic and several other markets. The board is equipped with Variscite DART-MX8M-Plus system-on-module and offers multiple camera interfaces to support BCON for MIPI, GigE Vision, and USB3 Vision cameras through Basler’s pylon Camera Software Suite. Basler prB-IMX8MP specifications with interfaces in bold usable by Basler cameras: SoC – NXP i.MX 8M Plus quad-core Cortex-A53 processor clocked at up to 1.8GHz, Cortex-M7 real-time core @ 800 MHz, 1080p H265/H264 encode/decode, AI/ML accelerator up to 2.3 TOPS, Vivante GC7000UL 3D GPU, Vivante GC520L 2D GPU System Memory – 8GB (CNXSoft: Probably a mistake since the DART-MX8M-PLUS module only supports 1GB to 4GB RAM. Is it 8 Gbit = 1GB?) Storage – 64 GB flash, MicroSD card slot Video Output – HDMI 2.0a up to 1080p60, 2-lane MIPI DSI […]

TTGO T-Block modular ESP32 devkit supports “Trolley” covers acting as display, buttons, sensor, proto area, etc…

When I first LilyGO TTGO T-Block ESP32 devkit with an enclosure and a display it reminded me of the M5Stack Core2 devkit, but it’s actually different as LilyGO designed a modular system that allows users to change the functionality of the top cover with expansion boards called “Trolleys”. That means TTGO T- Block can be fitted with a small e-Ink display, a prototyping cover, an RGB LED matrix, a small board that supports various MQ gas sensors, touch buttons, or a Trolley board equipped with headers compatible with common Arduino modules. TTGO T-Block Host 9102 preliminary specifications: WiSoC – ESP32 dual-core processor @ 240 MHz with 520KB SRAM, WiFi 4 and Bluetooth LE 4.2/5.x connectivity Memory – 8MB PSRAM Storage – 16MB SPI flash, MicroSD card slot USB – 1x USB Type-C for power and programming via CH2104 USB to TTL chip Trolley interface – 20-pin connector with 17x GPIO, […]

Inkplate 6COLOR – A 5.8-inch e-paper color wireless display (Crowdfunding)

Inkplate 6COLOR is a 5.8-inch color e-paper display equipped with ESP32 WiSoC to provide WiFi and Bluetooth LE connectivity, and programmable with the Arduino IDE or MicroPython. We’ve covered Inkplate ESP32-based e-paper displays since Inkplate 6 was launched in 2019, and since then the company introduced a larger model and an upgraded variant with a touchscreen display and higher resolution. But so far, all were grayscale models, and Inkplate 6COLOR is the first to come with color, or more exactly 7 colors. Inkplate 6COLOR specifications: Wireless module with dual-core ESP32 processor, Wi-Fi 4 & Bluetooth 4.0 (BLE) connectivity External storage – MicroSD card socket Display – 5.8-inch, 600 x 448 e-paper display with 7 colors (Black, White, Red, Yellow, Blue, Green, Orange) 128 DPI 25 seconds refresh time (manufacturer); tested by Inkplate: 10 to 11 seconds USB – 1x USB Type-C port for programming and power Expansion – Headers for […]

MIPI CSI-2 v4.0 adds features for always-on, low power machine vision applications

While MIPI CSI-2 standard was first introduced in 2005 as a high-speed protocol for the transmission of still and video images from image sensors to application processors, the standard has evolved over the years, and the latest MIPI CSI-2 v4.0 introduces features to better support always-on, low power machine vision applications, high-resolution sensors, and high-dynamic-range automotive image sensors. The main changes for v4.0 include support for a two-wire interface (MIPI I3C) to lower cost and complexity, multi-pixel compression for the latest generation of advanced image sensors, and RAW28 color depth for better image quality and an improved signal-to-noise (SNR) ratio. MIPI CSI-2 v4.0 highlights: Always-On Sentinel Conduit (AOSC) – Enables always-on machine vision systems with ultra-low-power image sensors and video signal processors (VSPs) continuously monitoring their surrounding environments and having the ability to wake up their more powerful host CPUs when specific events happen. Some use cases include laptop/tablet-based face […]

Raspberry Pi 4 to support Network install to a blank MicroSD card

The Raspberry Pi 4 will soon be able to install Raspberry Pi OS without the need for external hardware to flash the image. Raspberry Pi Network install will allow users to install a blank MicroSD card into their board, which will trigger the launch of Raspberry Pi Imager on the Raspberry Pi, and flash the image downloaded from the Raspberry Pi website. So far in order to install Raspberry Pi OS, you had to download Raspberry Pi Imager on a computer or a working Raspberry Pi, insert the MicroSD card into the host, and flash the image, before moving the MicroSD card into the Raspberry Pi board. This works just fine for most people, but if the Raspberry Pi is your only computing device, as may be the case in developing countries, that does not work. Network Installs may also speed up the installation process in the classroom where multiple […]
