Axelera M.2 AI accelerator module is said to deliver up to 214 TOPS of AI inference and up to 3200 FPS with ResNet -50 in a compact M.2 2280 form factor. Few details are available at this time, but the module is based on the company’s Metis AIPU (AI Processing Unit) using in-memory computing based on arrays of SRAM memory devices used to “store a matrix and perform matrix-vector multiplications “in-place” without intermediate movement of data”. This technology is said to “radically” increase the number of operations per computer cycle with without suffering from issues such as noise or lower accuracy. The Metis AI platform delivers 50+ TOPS per core (RISC-V-controlled dataflow engine), offers FP32 equivalent accuracy, and has a 15 TOPS/W energy efficiency. The last point is impressive, but that means 214 TOPS won’t be reachable with the module shown above, since the M.2 form factor is designed to […]
EdgeBox-ESP-100 – An ESP32-S3 industrial controller with RS485, CAN Bus, DIO, 4G LTE, and more
We’ve previously covered the EdgeBox-RPi4 industrial controller powered by a Raspberry Pi Compute Module 4 and plenty of I/Os such as RS485, RS232, digital inputs and outputs, and connectivity options such as Gigabit Ethernet, WiFi 5, Bluetooth 5, and 4G LTE. But if you don’t quite need the power of a Linux controller, the EdgeBox-ESP-100 industrial edge controller based on an ESP32-S3 dual-core WiFi and Bluetooth microcontroller and offering a similar set of features, albeit with twists, may be an interesting option. EdgeBox-ESP-100 specifications: Microcontroller – Espressif Systems ESP32-S3 dual-core Tensilica LX7 microcontroller @ 240 MHz with AI vector instructions, 512KB RAM Memory – 8MB PSRAM Storage – 16MB Flash Network connectivity 10/100M Ethernet RJ45 port 2.4 GHz WiFi 4 and Bluetooth 5.0 LE via ESP32-S3 4G LTE cellular via SIMCom A7670G LTE Cat 1 module Optional support for LoRa (replaces the A7670G module) Serial & I/Os via terminal blocks […]
JetHome JetHub D1+ automation controller runs Armbian with mainline Linux, supports Home Assistant
Earlier this year, we noted the addition of the JetHome JetHub D1 Linux-based home automation controller to mainline Linux 5.16, and the JetHome JetHub D1p (D1+) was just added to Linux 6.1 with some improvements. Still based on the Amlogic A113x processor, the JetHub D1+ gets more memory and storage with 2GB DDR4 RAM and 32GB eMMC flash, a MicroSD card slot, a new RTL8822CS wireless module, and a micro USB port to easily access the console and/or flash firmware to the device. JetHub D1+ specifications: SoC – Amlogic A113x quad-core Cortex A53 processor @ up to 1.5 GHz System Memory – 2GB DDR4 Storage – 32GB eMMC flash, MicroSD slot Connectivity 10/100M Ethernet RJ45 port Dual-band WiFi 5 up to 867 Mbps and Bluetooth 4.2/5.0 (RTL8822CS) Texas Instruments CC2652P1 Zigbee 3.0 module USB 1x USB 2.0 Type-A host port for peripherals 2x Micro USB ports one console access and […]
Gowin R86S mini PC offers 2.5GbE and 10GbE networking for $310 and up
Gowin R86S (aka GW-R86S) is an affordable Intel Celeron N5100 or Pentium N6005 Jasper Lake mini PC, router, and firewall appliance with 2.5GbE and 10GbE networking that sells for $310 and up on Aliexpress. 10GbE used to be reserved for the enterprise market due to the cost of hardware, but costs have gone down a lot as illustrated by the Gowin R86S system with up to three 2.5GbE ports, two 10GbE SFP+ cages, as well as ports that you would typically find a mini PC such as HDMI 2.0 video output, M.2 socket for NVMe SSD, two USB 3.0 ports, and a WiFi module. Gowin R86S specifications: SoC (one or the other) Intel Celeron N5105 quad-core Jasper Lake processor @ 2.0GHz / 2.9GHz (Turbo) with Intel UHD graphics 605; 10W TDP Intel Pentium N6005 quad-core Jasper Lake processor @ 2.0GHz / 3.3GHz (Turbo) with Intel UHD graphics @ up to […]
Brume 2 router review with WireGuard, OpenVPN, Tor, and Adguard Home
We started the review of GL.inet GL-MT2500A security gateway, aka Brume 2, with an unboxing and teardown, and I’ve now had time to test the router in more detail so I’ll report my experience using the router with OpenVPN and WireGuard VPN, Tor, Adguard Home, and more. In a nutshell, it’s super easy to use, unless your ISP causes troubles, which it did in this case. Brume 2 connection and initial setup I connected the WAN port of the Brume 2 router to 3BB’s modem router (3BB is an ISP in Thailand), the LAN port to my laptop, and finally the USB-C power supply (power draws is 2.3 Watts at idle). Let’s now go to the dashboard using the default IP (192.168.8.1). This will take us through the configuration wizard to select the language and set up the admin password. I was then immediately greeted by an “Upgrade Reminder” and […]
Giveaway Week – GL.iNet GL-S10 BLE to MQTT Gateway
The sixth prize of this year’s Giveaway Week will be GL.iNET GL-S10 BLE to MQTT gateway based on the ESP32 microcontroller and offering Ethernet, WiFi, and Bluetooth LE connectivity. The gateway is used to gather data from Bluetooth LE devices such as beacons and can be used in warehouses, shopping malls, airports, exhibition halls, tourist attractions, etc… for personnel management, asset management, environmental monitoring, indoor navigation, and more. I reviewed the ESP32-based BLE to MQTT gateway with the provided BLE beacon at the end of last year using MQTT X open-source client and the GL-S10 Tool App for Android. It allowed me to send commands through MQTT topics, for example, to set or retrieve the beacon’s (WiFi) configuration, and receive the data through MQTT subscriptions. Some of the data include the MAC address, RSSI, ad (Broadcast data advData), and a timestamp. It took some effort to get it working, but […]

GL.iNet GL-MT2500A security gateway review – Part 1: Unboxing and teardown
The Brume 2 security gateway/router is powered by a MediaTek MT7981B (Filogic 820) dual-core processor @ 1.3 GHz and is available as the GL-MT2500A with a metal enclosure or the GL-MT2500 with a plastic case. GL.iNet sent me the GL-MT2500A for review. In the first of the review, we’ll have a look at the device and accessories, and tear it down to check out the hardware design and main components. I’ll then need some time to test OpenWrt 21.02 and features such as WireGuard and OpenVPN, AdGuard Home, Tor Anonymity, and soon. GL.iNet GL-MT2500A (Brume 2) unboxing The router ships with a short Ethernet cable, a 5V/2A USB Type-C power supply with EU, US, and UK plug adapters, and some minimal documentation that points to the users to more detailed online documentation and support on the company’s Facebook page. There’s not much too see on the front panel and right […]
