10.1-inch RPI All-in-One PC review with Raspberry Pi 4

10.1-inch Raspberry Pi PC portrait mode

A couple of months ago I received “RPI All-in-One”, a 10.1-inch touchscreen display for Raspberry Pi boards, listed the specifications, checked out the package content, installed a Raspberry Pi 4 inside the display before booting my new all-in-one (AiO) PC successfully. I’ve now had time to spend more time with the PC/display and see how it performs under various conditions. I also tested HDMI and USB-C input features with a laptop and mini PC. Fan or fanless operation? After updating Raspberry Pi OS, I ran sbc-bench.sh script together with rpi-monitor to see how the Raspberry Pi 4 with 1GB RAM would perform under load with the (noisy) fan enabled.

  No throttling was detected, and the temperature never exceeded 56°C in a room with an ambient temperature of 26°C. I then disconnect the fan, but it turns out the fan can also be easily disabled in the OSD menu […]

Wiliot Starter Kit for retailers features a smart coffee cup tracking temperature, fill level, location, etc…

smart coffee cup with sensors, energy harvesting

Wiliot Starter Kit aims to demonstrate the ability of the Wioliot’s self-powered IoT Pixel and cloud services to retailers with a kit including a Coffee cup that’s capable of tracking liquid temperatures, fill level, motion, location changes, humidity, and proximity. The kit was previously only available to larger retailers through a “controlled release model”, but the company has now switched to an “open model” so that any retailers can use the technology to track products and packages. Let’s what’s included inside the start kit, and try to understand how the Wiliot solution works. Wiliot Starter Kit includes the following hardware: 1 x IoT Pixel-ready Coffee Cup 5 x Single-Band IoT Pixels mounted on cardboards 5 x Dual-Band IoT Pixels mounted on cardboards 1 x Single-Band Bridge Device 1 x Dual-Band Bridge Device You’ll also get 6 months of Wiliot Cloud Services, access to the Wiliot community forum & support Portal, […]

5-minute Cybersecurity Survey for IoT Device Manufacturers (Sponsored)

Cybersecurity survey IoT

Calling all software developers, hardware designers, product security engineers, QA, engineering managers, and executives in the field to participate in a global, industry-wide survey. With nearly 50 new CVEs found every day in 2021, 90% of hospitals hacked, and cybersecurity attacks constantly in the headlines, it’s time to take stock of security preparedness in IoT. Timesys, an industry pioneer in embedded software and cybersecurity for embedded, is taking on that challenge. And to get a better understanding of where IoT device manufacturers are in their cybersecurity journey, Timesys has launched a global, industry-wide survey. The entire survey is only ten questions and should take under five minutes to answer. The survey includes driving factors for security, security processes being implemented, specific technologies being used, security challenges companies are facing, and more. It’s designed to be a broad survey, geared toward developers, security teams, and engineering managers. Take the survey here. […]

Samsung Exynos 2200 SoC features Xclipse 920 GPU with AMD RDNA 2 architecture

Samsung Exynos 2200

Samsung has just unveiled the Exynos 2200 Armv9 SoC equipped with Samsung Xplipse 920 GPU based on AMD RDNA architecture and promising console quality graphics on mobile devices. Manufactured with a 4nm process, the octa-core processor also features Arm Cortex-X2, Cortex-A710, and Cortex-A510 cores, a 5G modem for up to 7.35 Gbps downlink, 8K video encoding and decoding, as well as support for LPDDR5 memory and UFS 3.1 storage. Exynos 2200 specifications: CPU 1x Arm Cortex-X2 3x Arm Cortex-A710 4x Arm Cortex-A510 GPU – Samsung Xclipse 920 GPU built with AMD RDNA 2 technology enabling hardware-accelerated ray tracing (RT) and variable rate shading (VRS), a first on mobile according to Samsung VPU Video decode – 8Kp60 10-bit HEVC (H.265), 8Kp30 10-bit VP9, AV1 Video encode – 8Kp30 10-bit HEVC(H.265), VP9 AI – AI Engine with Dual-core NPU and DSP up to 52 TOPS (TBC) Memory – LPDDR5 Storage – UFS […]

Raspberry Pi RP2040 is now available in quantities for 70 cents and up

Raspberry Pi RP2040 Reel

Raspberry Pi RP2040 microcontroller has been available for one dollar in single quantities for about half a year, with at the time, 500- and 3400-pieces reel pricing to be determined. But Raspberry Pi Trading has now started to sell the chip in bulk with reels of 3,400 and 500 pieces directly to businesses for a unit price of respectively 70 and 80 cents via the new Raspberry Pi Direct website. Distributors have been selling reels for a while, but closer to 85 cents to 95 cents per unit. That basically means smaller quantities should still be purchased through distributors, but it makes more sense to purchase reels directly from Raspberry Pi Trading. Eben Upton also says they have enough wafer stock to produce 20 million chips with more on the way, so no shortage is expected. That contrasts with the current situation with many STM32 microcontrollers when some companies have […]
