Silicon Labs BG24 and MG24 2.4 GHz wireless MCU’s quadruple AI performance at a fraction of the energy

Machine Learning is getting everywhere including into 2.4GHz wireless microcontrollers with SIlicon Labds BG24 Bluetooth and MG24 multi-protocol Cortex-M33 microcontrollers that improve AI/ML performance by 4 times using 1/6th of the energy thanks to a built-in AI accelerator. That makes the new microcontrollers suitable for battery-powered edge AI devices with support for Matter (coming soon) as well as PSA Level 3 Secure Vault protection. Silicon Labs expects the chips to be found in various smart home, medical and industrial applications. BG24 and MG24 share the same block diagram and the same specifications apart from the supported wireless protocols: MCU core – Arm Cortex-M33 @ 78.0 MHz with DSP instruction and floating-point unit Memory – Up to 256 kB RAM data memory Storage – Up to 1536 kB flash program memory Wireless CPU – Arm Cortex-M0+ 2.4 GHz Radio Performance -104.5 dBm sensitivity @ 250 kbps O-QPSK DSSS -104.9 dBm sensitivity […]

Building a NanoPi M4V2 based All-in-One Linux PC running Armbian (Ubuntu/Debian)

At the end of my review of “RPI All-in-One” PC with Raspberry Pi 4, I noted the system also appeared to be compatible with NanoPi M4V2 single board computer. I’ve now tried it out, and assembling the board inside the 10.1-inch display is even easier than I initially thought. That means I now have a NanoPi M4V2 All-in-One PC running Ubuntu Hirsute or Debian Buster with XFCE desktop environment from Armbian, and most features work including the display and wireless connectivity, but I still have an issue with the touchscreen function. Here are the steps I followed initially: Download Armbian Buster XFCE image from Armbian and flash it to a microSD card with tools like USBimager. Insert the microSD card in the board Install the USB Type-C and HDMI-A adapters in the display. Insert the USB Type-C and HDMI port of the NanoPi M4V2 SBC into the adapters Install the […]

MOREFINE M6 – An ultra-thin Jasper Lake mini PC (Crowdfunding)

We’ve seen a fair amount of Jasper Lake mini PCs, and even reviewed one with Beelink U59. MOREFINE M6 stands out due to its size and thickness, being about the size of two smartphones stacked together. The features are also promising with an Intel Celeron N5105 quad-core processor coupled with up to 16 GB RAM, up to 1TB M.2 NVMe SSD, as well as dual 4K video output through HDMI and USB-C ports, a 2.5GbE ports WiFi 6 & Bluetooth 5.2 connectivity, and three USB 3.1 ports. MOREFINE M6 specifications: SoC – Intel Celeron N5105 quad-core Jasper Lake processor @ 2.0GHz / 2.9GHz (Turbo) with Intel UHD graphics 605; 10W TDP System Memory – 8GB or 16GB LPDDR4 Storage – 512GB or 1TB M.2 NVMe 2280 SSD, or 256GB M.2 SATA SSD Video Output 1x HDMI 2.0 port up to 4Kp60 1x DisplayPort Alt Mode via USB-C port up to […]

Radxa E25 carrier board, 2.5GbE switch, and WiFi 6 router

Radxa E25 2.5GbE switch-Xiaomi AX6000 WiFi 6 router

I’ve just received an early sample of Radxa E25 dual 2.5 GbE carrier board for Radxa CM3 Plus (RK3568) system-on-module, a 2.5GbE TP-Link switch, and Xiaomi AX6000 WiFi 6 + 2.5GbE router. Here’s the back story before looking into the devices. I’ll soon have to review UP Xtreme i11 mini PC with a 2.5GbE port, and after writing about the upcoming ROCK5 Model B SBC with both 2.5GbE and WiFI 6/6E, I realized I should really get some hardware to test 2.5GHz and WiFi 6. So I started to ask what could be the best options for a $200 budget. While thinking about it, I remember Radxa was working on the Radxa E23 board with 2.5GbE, and adding a WiFi 6 USB dongle might be an option. But they told me Radxa E25 would be a better option with two 2.5GbE ports and support for WiFi 6, although that one […]

$499 BrainChip AKD1000 PCIe board enables AI inference and training at the edge

BrainChip has announced the availability of the Akida AKD1000 (mini) PCIe boards based on the company’s neuromorphic processor of the same name and relying on spiking neural networks (SNN) which to deliver real-time inference in a way that is much more efficient than “traditional” AI chips based on CNN (convolutional neural network) technology. The mini PCIe card was previously found in development kits based on Raspberry Pi or an Intel (x86) mini PC to let partners, large enterprises, and OEMs evaluate the Akida AKD1000 chip. The news is today is simply that the card can easily be purchased in single units or quantities for integration into third-party products. BrainChip AKD1000 PCIe card specifications: AI accelerator – Akida AKD1000 with Arm Cortex-M4 real-time core @ 300MHz System Memory – 256Mbit x 16 bytes LPDDR4 SDRAM @ 2400MT/s Storage – Quad SPI 128Mb NOR flash @ 12.5MHz Host interface – 5GT/s PCI […]
