WiFi 7 (802.11be) will support up to 40 Gbps links, real-time applications

Key features of WiFi 7 (802.11be)

I still don’t own a WiFi 6 router, but MediaTek has already started to demonstrate WiFi 7 (802.11be) to customers with solutions based on upcoming Filogic 802.11be processors which deliver “super-fast speeds and low latency transmission” and provide a “true wireline/Ethernet replacement for super high-bandwidth applications”. The company goes on to explain that Wi-Fi 7 relies on the same 2.4GHz, 5GHz, and 6GHz frequencies as WiFi 6/6E, but can still provide 2.4x higher speeds than Wi-Fi 6, even with the same number of antennas, since WiFi 7 can utilize 320Mhz channels and support 4K QAM (quadrature amplitude modulation) technology.   There’s limited information about MediaTek Filogic 802.11be WiFi 7 processors since it will take a few more years before becoming available, but we can find more details in a document entitled “Current Status and Directions of IEEE 802.11be, the Future Wi-Fi 7” from IEEE Xplore. Here are some of the […]

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, […]

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 […]
