Tiny Rock Pi S SBC gets PoE & audio HAT add-on board

Powered by a Rockchip RK3308 quad-core Cortex-A35 processor, Radxa Rock Pi S single board computer was launched with specifications listing PoE support via an add-on board. Just one little problem though: it was not available for sale. The good news is that Radxa has now launched a PoE HAT for the Linux SBC adding support for 802.3af PoE up to 10W input, making it one of the smallest single board computers with PoE support in the world, and adding audio features with a 3.5mm audio jack, and an FPC connector for a microphone array. It can be purchased on Seeed Studio for $13.00. Here are the specifications of the complete solution with Rock Pi S SBC and PoE HAT: SoC – Rockchip RK3308 quad-core Arm Cortex-A35 processor @ up to 1.3 GHz with built-in Voice Activity Detector (VAD) System Memory – 512MB RAM Storage – 1GB SD NAND flash, MicroSD card socket, EEPROM for HAT identity and driver probe Connectivity […]

AAWireless Enables Wireless Android Auto on Android 9.0+ Smartphones (Crowdfunding)

Android 11 was just released yesterday with wireless Android Auto support removing the need to use a cable between your phone and a car running Android Auto. That’s great if you have a phone that got upgraded to Android 11, but what about people with older smartphones or people equipped with a wired Android Auto infotainment system? AAWireless offers a solution for phones running Android 9.0 or greater as a plug & play USB device that allows the use of a WiFi connection instead of a USB cable. Emil Borconi-Szedressy started the project in 2018 with the AAGateway app allowing you to use an auxiliary (slave) device to connect your existing Android Auto compatible car to your phone (master) using a hotspot created on your phone. This is not ideal since should need a spare Android phone to run the slave device. AAWireless removes this need as Emil ported the solution to Linux, and used an inexpensive and tiny RockPi […]

CrowPi2 Raspberry Pi 4 Education Laptop Review

I started my review of CrowPi2 Raspberry Pi 4 Learning Kit a while ago and at the time I showed content from the kit and its first boot. I’ve now spent more time with this very special Raspberry Pi 4 laptop and will focus this review on the education part, namely CrowPi2 software, but will also look at thermal cooling under stress with and without a fan, and try to install another Raspberry Pi compatible board inside the laptop shell. CrowPi2 Education Software It’s quite important to read the user manual before getting started as there are a few non-intuitive steps you may have to take. First I assume the wireless keyboard would just connect after pressing the power button, but it did not. The user manual explains the RF dongle is inside the mouse, and once you connect it you’ll be able to use the keyboard that has some battery charge out of the box, and can be charged […]

Rock Pi 4C SBC with 4GB RAM, HDMI and DisplayPort Launched for $59 and up

Last October, Radxa unveiled Rock Pi 4C SBC as an update to the company’s Rock Pi 4 SBC, with the same Rockchip RK3399 hexa-core processor, 4GB RAM, but instead of providing one HDMI output only, Rock Pi 4C board offers two video output just like Raspberry Pi 4 board, but with a twist, since it combines a micro HDMI port with a Mini DisplayPort connector. It’s all good except for one small detail. So far, it was not possible to purchase the board. The good news is that Radxa has now announced the availability of the board for just $59 on AllNetChina. You can also buy Rock Pi 4C on other platforms, but the price is much higher at $109.99 on Amazon, and $99.99 on Aliexpress. Rock Pi 4C specifications: SoC – Rockchip RK3399 big.LITTLE hexa-core processor with 2x Arm Cortex-A72 @ up to 1.8 GHz, 4x Cortex-A53 @ up to 1.4 GHz Mali-T864 GPU with support OpenGL ES1.1/2.0/3.0/3.1/3.2, Vulkan […]

YARC Case Can House a Raspberry Pi Board with one HAT Expansion Board and Up to 3 Hard Drives (Crowdfunding)

There are plenty of enclosures for Raspberry Pi board and other compact x86 or Arm Linux SBCs, but many projects require expansion boards and it’s not always possible to use an off-the-shelf case. That’s with that in mind that Stefano Zorzi and other enthusiasts have created YARC (Yes, Another Raspberry Case), a hexagonal case that supports the most popular single board computers, even when an add-on board – such as a Raspberry Pi HAT – is attached to the board. There’s enough space for up to three 2.5″ hard drives. Those are the boards officially supported (tested?) with the case: Raspberry Pi B +, 2B, 3B, 3B +, 4B, A +, 3A + Hardkernel ODROID C1, C2 AAEON Up Board Asus Tinker board and Tinker board S Radxa Rock Pi 4 Orange Pi PC, Pi PC2, Pi PC Plus Basically any board with compatible mounting holes can be installed in YARC case. There’s plenty of space for whatever cables you […]

Linux 5.6 Release – Main Changes, Arm, MIPS & RISC-V Architectures

Linus Torvalds has just announced the release of Linux 5.6 on the Linux Kernel Mailing List: So I’ll admit to vacillating between doing this 5.6 release and doing another -rc. This has a bit more changes than I’d like, but they are mostly from davem’s networking fixes pulls, and David feels comfy with them. And I looked over the diff, and none of it looks scary. It’s just slightly more than I’d have preferred at this stage – not doesn’t really seem worth delaying a release over. So about half the diff from the final week is network driver fixlets, and some minor core networking fixes. Another 20% is tooling – mostly bpf and netfilter selftests (but also some perf work). The rest is “misc” – mostly random drivers (gpio, rdma, input) and DTS files. With a smattering of fixes elsewhere (a couple of afs fixes, some vm fixes, etc). The shortlog is appended, nothing really looks all that exciting, […]

Year 2019 in Review – Top 10 Posts and Stats

Happy New Year 2020

2019 is closing to an end, or you may already be into 2020 while reading this post. In any case, that means it’s time to look back at 2019 and look forward to the events and new products to take place next year. While 2018 was a boring year for new processors, 2019 brought us some interesting new chips such as Amlogic S922X / A311D, or the first Arm Cortex-A55 only processors such as Amlogic S905X3. Rockchip RK3399Pro was promising when it was announced last year, but it never really took off. It was a pretty quiet year for Allwinner as well. RISC-V architecture has been ramping up with the first general-purpose RISC-V MCU: GD32V, WCH CH572 Bluetooth LE MCU, the launch of more SiFive RISC-V cores, and Kendryte K210 RISC-V AI processor announced last year has found its way into more and more boards. There have also been the usual launches of mobile Arm processors from Qualcomm, Samsung, and […]
