Giveaway Week – NanoPi M4V2 SBC & Metal Case Kit

Let’s finish giveaway week 2019 on a high with FriendlyELEC NanoPi M4V2 single board computer, and its metal case kit. The board features a Rockchip RK3399 processor with 4GB LPDDR4 RAM, and the metal case kit allows the addition of an NVMe M.2 SSD as well. I tested the mini PC with FriendlyCore Desktop based on Ubuntu 18.04, since at the time, Armbian was still not working with the updated board equipped with LPDDR4 memory, and Android requires an eMMC flash module which was not part of the kits I received. NanoPi M4V2 performed fairly well in the case, but the fan is quite noisy, and somehow the RAM bandwidth was almost half of the one in the earlier NanoPi M4 board with DDR3 memory, which is the opposite one would expect. Probably related to some software tweaks as explained in the comments section of the review. I received two […]

HLK-7688A OpenWrt Development Board Comes with an Audio Jack

We first tested MediaTek MT7688 MIPS processor in Mediatek Labs’ LinkIt Smart 7688 / 7688 Duo hardware development kits running OpenWrt in 2015 with the boards having a focus on IoT applications. A year later, Widora NEO board launched with an audio jack for connected audio applications, but AFAIK it’s not available anymore. There’s now another OpenWrt audio board based on the processor with HLK-7688A board featuring Hi-Link HLK-7688A module which we previously found in MatchBox LoRaWAN gateway. HLK-7688A board specifications: Wireless Module – HLK-7688A based on MediaTek MT7688 MIPS24KEc processor @ 580 MHz, and equipped with 128MB RAM, 32MB flash Storage – MicroSD card slot Connectivity 802.11 b/g/n WiFi 4 up to 150 Mbps with u.FL antenna connector 10/100M Ethernet Audio – 3.5mm audio jack; 4-pin speaker header, WM8960 audio codec USB – 2x Micro USB ports one USB 2.0 port and one for debugging & power Expansion – […]

DepthAI Brings AI plus Depth to the Raspberry Pi (Crowdfunding)

Edge computing on the Raspberry PI has been a bit of ups and downs, especially with everyone gearing for AI in everything. The Raspberry Pi, on its own, isn’t really capable of any reliable AI applications. Typical object detection on the Raspberry Pi would get you something around 1 – 2 fps depending on the nature of your model and this because all those processing is done on the CPU. To address this poor performance of AI applications on the Raspberry Pi, AI Accelerators came to the rescue. The Intel Neural Compute Stick 2 is one such accelerator capable of somewhere around 8 – 15 fps depending on your application. The NCS2, which is based on the Myriad X VPU technology, offers so much more than the compute stick delivers, and this is something that the team behind DepthAI has exploited to create a powerful AI module for edge computing […]

Fix for Raspberry Pi 4 4GB model’s USB Ports not Working on Ubuntu 19.10

Ubuntu 19.10 server was recently released with official support for Raspberry Pi 4 SBC. Shortly after I read stories about the USB ports not working on the board, but it took another interesting turn as Canonical now explains the bug only affects RPI 4 with 4GB RAM, and USB works just fine on boards with just 1/2GB RAM. The issue has been identified and it’s been found to be a kernel bug with a solution in the works that being tested. In the meantime, you can access to your Raspberry Pi 4 4GB USB ports by limiting the memory to 3GB in /boot/firmware/usercfg.txt as follows:

total_mem=3072

1	total_mem=3072

Alternatively here’s the link to an updated kernel provided by Hui Wang with you want to test it out: I built a testing kernel, not only includes the fix for USB host, but also includes all new patches from https://github.com/raspberrypi/linux.git rpi-5.3.y branch (about 107 […]

Giveaway Week – Balena Fin Developer Kit

balenaFin, RPi Compute Module, Power Supply, Enclosure

We’ve been organizing “giveaway weeks” every year since 2014 on CNX Software to send some of the review samples to our readers. Let’s do it again in 2019 starting with Balena Fin developer kit based on Raspberry Pi 3+ Computer Module (CM3+) with 8GB flash and a carrier board in order to get started with BalenaOS operating system and the company’s balenaCloud service. Instead of a traditional review, we wrote a getting started guide for balenaFin Developer Kit, balenaOS and balenaCloud, where we explain how to flash the OS to the board, configure it, run a container, and manage the device, including container updates, from Balenacloud. The winner will receive the full kit below with carrier board, Raspberry Pi CM3+ module, CR1225 battery, enclosure, power supply, and MicroUSB cable. It will come already assembled as shown in the first photo. To enter the draw simply leave a comment below. Other […]
