The Raspberry Pi boards are great little Arm Linux SBC’s with a low price and great community support. But the Broadcom processors used in the boards are also fairly old so they may not be suitable for some projects. If your application needs or would benefit from modern features such as memory over 1GB RAM, an actual Gigabit Ethernet port, USB 3.0 port(s), 4K video output, or H.265 hardware video decoding you’ll have to find Raspberry Pi alternatives. I’ll point out 5 alternative single board computers in this post from the point of view of existing Raspberry Pi users, who will want good software support and a board with the same or similar form factor as Raspberry Pi 3 Model B/B+ in order to reuse their add-on boards and/or enclosures. Price has to be competitive as well, so nothing above $80 will be mentioned. The boards are not listed in […]
E-ALE is a Free & Open Source Linux Training Program for Embedded Engineers
As I wrote about the Embedded Linux Conference 2019 schedule a few days ago, I found out one of talk planned to use E-ALE hardware kit for the session. I had never heard about this kit, but a quick search led me to e-ale.org website which explains E-ALE stands for Embedded Apprentice Linux Engineer. The training program is made for embedded engineers with experience designing firmware for microcontrollers, but now need to transition to embedded Linux. Training only happens in-person (no webinar) at existing Embedded Linux conferences and is comprised of 8 to 9 seminars over 2 to 3 days. It usually starts with a presentation on one subject, followed by lab time to practice the relevant learned skills. The training takes place on the E-ALE kit at each conference, but it does not refer to a specific hardware platform. In most conferences, the PocketBeagle and BaconBits add-on board are […]
Embedded Linux Conference & Open Source Summit 2019 Schedule
In the last few years, I covered the Embedded Linux Conference and IoT Summit schedules since both were happening at the same time and in the same location. But the Linux Foundation have recently announced the Embedded Linux Conference will combine with the Open Source Summit, so the IoT Summit appears to have been phased out. The full schedule for the events taking place on August 21 – 23, 2019 at the Hilton San Diego Bayfront, USA, has also been released, so I’ll create a virtual schedule with some of the sessions most relevant to this blog. Wednesday August 21, 2019 11:30 – 12:05 – What’s New with U-Boot? by Simon Glass, Google LLC U-Boot is a widely used bootloader in embedded systems. Many users are unaware of the wide feature-set of U-Boot, particularly features added in the last few years. This talk aims to bring users (and prospective users) […]
Raspberry Pi based Hyper Keyboard Pi & hgTerm Handheld PCs, and RasPi Arcade Stick
There are so many products and projects based on Raspberry Pi that it’s difficult to keep track, and many are often not that interesting, not because they are not useful, but instead because it just feels we’ve seen those before. But this week I’ve come accross three projects that looks to be newsworthy including two handheld computers with a 4″ display, and one retro-gaming console with standard arcade buttons and controls similar to what is found in Pandora’s Box/Key 5S. hgTerm DIY Raspberry Pi Handheld Computer hgterm is a portable computer based on a stripped down Raspberry Pi 3 where the Ethernet port, HDMI port, and most of the USB ports have been removed. It features a 4″ touchscreen display, a Bluetooth keyboard all housed in a 3D printed case. It’s not actually a product that you can buy (yet), but a project made by Igor Brkić which you can […]
One Mix 3 Yoga 8.4″ Mini Laptop is up for Pre-order for $760
In recent years we’ve seen several companies launch “mini laptops” with small 6″ to 7″ displays. They have the advantages of being really compact and lightweight, and thanks to Intel Gemini Lake & Amber Lake processors can be fairly powerful. The problem is that with small displays come small keyboards, and people have had a hard type typing text on those. So we’ve started seeing announcements for mini laptops with 8″ to 8.9″ displays such as GPD Pocket 2 Max and CHUWI minibook that should make like easier at the cost of a slightly larger and heavier devices. One Mix 3 Yoga appears to be one the first of those ultra mobile PCs for sale, or more exactly pre-order. You’ll find the pocket laptop on GeekBuying for $759.99 with shipping scheduled for next month. One Netbook One Mix 3 Yoga specifications: SoC – Intel Core m3-8100Y dual-core/quad-thread Amber Lake processor […]
Blueendless X3 Networked “HDD NAS Case” Runs Ubuntu on Marvell ARMADA 3720 SoC
We’ve previously covered inexpensive Kimax’ Ethernet & WiFi HDD enclosures for 2.5″ SATA drives, powered by MediaTek processor and running OpenWrt. If you need something more powerful and versatile yet still affordable, the easiest way is now likely to go with SBC based solutions such as ODROID-HC1/HC2 or dual SATA NAS enclosure for RockPro64. There may be another interesting option, as I’ve just been informed about another model of those networked HDD enclosure called Blueendless X3 “HDD NAS case” with Ethernet only (no WiFi), and that is equipped with the same Marvel ARMADA 3720 dual core Cortex-A53 processor as found in Marvell ESPRESSOBin board. Blueendless X3 specifications: SoC – Marvell ARMADA 3720 (88F3720) dual core Cortex-A53 processor @ up to 1.1 GHz System Memory – 512 MB DDR3 Storage – 16GB eMMC flash for OS, SATA 3.0 interface for 2.5″ drives based on ASMedia ASM1092R port multiplier Networking – 1x […]
More Intel Processor HW Security Flaws. Meet Microarchitectural Data Sampling (MDS)
2018 did not start so well for processor vendors, especially Intel, but also AMD, Arm and others as some of their processors leveraging speculative execution were impacted by Spectre and/or Meltdown hardware security bugs. The workarounds to improve security had a downside as they affected performance in some specific use case. Panic ensued as the bug was revealed to the public a bit too early, so companies were not fully ready with their mitigations / workarounds. Then in summer of 2018, another hardware security flaw known as Foreshadow or L1 Terminal Fault came to light. The new flaw potentially enabled the attacker to access data stored in L1 cache. Provided you have updated your operating systems to the latest version, your computers and devices should be protected against those vulnerabilities, and you can even check with a script working in Linux or FreeBSD. But this now looks like a never […]
ToyBrick RK3399Pro Board Shown to Outperform Jetson Nano SBC
NVIDIA created a lot of buzz when they released $99 Jetson Nano SBC featuring a 128-core Maxwell GPU, and said to deliver 472 GFLOPS of compute performance for running modern AI workloads with a power consumption of around 5 watts. But Jetson Nano is not the only low cost platform to deliver high performance at low power for AI workloads, as for example Rockchip RK3399Pro (RK1808 NPU) found in boards such as Toybrick RK3399Pro is said to deliver 3 TOPS for INT8, 300 GOPS for INT16, and 100 GOPS for FP16 inferences. Those operations per second numbers can be confusing and misleading, so it’s important to check out the performance of actual neural network models, and Rockchip did provide some RK3399Pro benchmarks last year for Inception V3, ResNet34 and VGG16 models comparing the results to Apple A11, Huawei Kirin 970, and NVIDIA Jetson TX2. However, ideally you’d want result from […]
