Another consequence of supply shortage: mass production mishaps

mass production mishap IP2315 CH224D

Chips may suddenly disappear from the supply chain or get really expensive due to the recurring supply shortage, companies are now designing their PCBs to support multiple chips either selecting drop-in replacements or creating multiple footprints to cater to at least one alternative part. That means one PCB and multiple bill-of-materials are needed to be more resilient to any supply disruption. Radxa did that on the ROCK 3A board for the USB PD circuitry with the ability to use either Injoinic IP2315 or WCH CH224D IC. Those are not pin-to-pin compatible chips, and two circuitry were made for the board requiring two BoMs as it’s not just possible to only replace IP2315 by CH224D. But this information did not get to the inventory manager, and once IP2315 was out of stock, he/she believed it would be possible to simply replace IP2315 with CH224D. The unlucky part is that the factory […]

Raspberry Pi 4 gets Vulkan 1.2 conformance, Android Vulkan support

Vulkan deferred shading with shadows

Iglia has done more work on the graphics driver for the VideoCore VI GPU found in Raspberry Pi 4 and other Broadcom BCM2711-based hardware with Vulkan 1.2 conformance, and Roman Stratiienko added Vulkan 3D graphics acceleration to Android, or more exactly LineageOS. Raspberry Pi and Iglia have been collaborating together since the launch of the Raspberry Pi 4 SBC to develop a Khronos conformant Mesa 3D graphics driver for the board, and that’s a long-term project that’s been going on for over two years, and not quite finished yet. Here’s a non-exhaustive timeline of the project so far: February 2020 – Raspberry Pi 4 V3DV driver gets OpenGL ES 3.1 conformance, work on Vulkan starts with the basic triangle demo showcased June 2020 – Vulkan driver source code released with many demos working on Raspberry Pi 4 October 2020 – Iglia gives a project update status presentation for Raspberry Pi […]

ACTAMID M8S – An Intel Pentium N6005 palm-sized PC with dual Gigabit Ethernet, 3x HDMI ports (Crowdfunding)

ACTAMID M8S

ACTAMID M8S is a palm-sized 3.4-inch mini PC powered by an Intel Pentium N6005 Jasper Lake processor with up to 16GB LPDDR4 memory, 1TB M.2 2242 SSD. The M8S is bigger than the recently announced 2.7-inch PIX NII mini PC based on the same processor, but that’s for a good reason since it offers more ports with three HDMI outputs, dual Gigabit Ethernet, and three USB 3.0 ports. The mini PC also features WiFi 6 and Bluetooth 5.2 wireless connectivity, a quiet fan, and a 7-color LED backlight for good effects… Win Element Technology Co., Ltd, the Hong Kong company owning the ACTAMID brand, says the mini PC ships preinstalled with an activated version of Windows 11, but also supports Linux distributions such as Ubuntu 20.04. ACTAMID M8S specifications: SoC – Intel Pentium N6005 quad-core processor @ 2.0GHz / 3.3GHz (Turbo) with Intel UHD graphics @ up to 900 MHz; […]

ESP-WIFI-CSI detects humans with WiFi signals only, no sensor needed

ESP-WiFi-CSI

Espressif ESP-WIFI-CSI software relies on the disturbance in the force WiFi signals between one or more ESP32 boards and a router to detect whether humans are present in a room, or even indoor positioning, providing a cost-effective solution since no sensors are needed. Channel state information (CSI) leverages carrier signal strength, amplitude, phase, and signal delay indicators to reveal the signal scattering, reflection, and power attenuation phenomena that occur with the carrier as the transmission distance changes. This is typically used to measure the channel status of the wireless network in Wi-Fi communication, but it’s also possible to analyze and study the changes in CSI to detect movements such as walking and running of people or animals, and Espressif claims it can also capture subtle movements caused by small movements such as breathing and chewing of people or animals in a static environment. ESP-WIFI-CSI implementation works with all ESP32 series […]
