NanoPi NEO3 Headless SBC Launched for $20 and up

Last month, we found out FriendlyELEC was working on NanoPi NEO3, a tiny SBC powered by Rockchip RK3328 processor and made for headless applications and networked storage thanks to Gigabit Ethernet and USB 3.0 ports, as well as a 26-pin GPIO header. At the time, the board was still been finalized, but the company has now started to take orders for $20 and up depending on options which include a cute white enclosure.. Here’s a quick reminder of NanoPi NEO3 specifications: SoC – Rockchip RK3328 quad-core Arm Cortex A53 processor with Mali-450MP2 GPU System Memory – 1GB or 2GB DDR4 Storage – MicroSD Slot for system boot and storage Video Output – N/A Connectivity – Gigabit Ethernet with unique MAC via RTL8211E PHY USB – 1x USB3.0 Type-A port, 2x USB2.0 on 2.54mm 8-pin header Expansion – 26-pin header with I2C, UART, SPI, I2S, GPIO Debugging – 3-pin header for […]

Debian based Mobian Linux OS Brings Librem 5 Phosh Shell to Pinephone

2020 is the year of the Linux phone. Sort of… At least, we now have smartphones that ships with Linux thanks to PinePhone and Librem 5, and several Linux mobile operating systems with Ubuntu Touch based UBPorts, postmarketOS, and others. Mobian is another Linux distribution which as its name implies is based on Debian and targets mobile devices. Interestingly, the project relies on Purism Phosh phone shell/user interface used in Librem 5, but the first Mobian image has been released for PinePhone with plans for PineTab and Librem 5 support coming later. Mobian supports a nice list of apps include Chromium, Firefox ESR, Calls, Files, Telegram messaging app, MPV media player, GNOME 2048, and more 3D graphics works, you can make phone calls, browse the web, and use GPS/GNSS applications, but it’s still work in progress as for example, USB and the camera does not work, the phone may take […]

Tiny NanoPi NEO3 SBC Targets Networked Storage with GbE and USB 3.0

Once upon a time, FriendlyELEC launched a Raspberry Pi Zero competitor for headless applications with Allwinner H3 powered NanoPi NEO, which was then followed with NanoPi NEO2 equipped with a more powerful Allwinner H5 processor and Gigabit Ethernet, and less than two years ago, NanoPi NEO4 was launched with Rockchip RK3399 hexa-core processor, 1GB RAM, and HDMI output. “Wait! What happened to NanoPi NEO3?!” you may ask. It probably got lost in the woods, but FriendlyELEC found it under a rock, and are about to launch NanoPi NEO3 SBC based on Rockchip RK3328 and offering a USB 3.0 port and Gigabit Ethernet network connectivity. NanoPi NEO3 specifications: SoC – Rockchip RK3328 quad-core Arm Cortex A53 processor with Mali-450MP2 GPU System Memory – 1GB or 2GB DDR4 Storage – MicroSD Slot for system boot and storage Video Output – N/A Connectivity – Gigabit Ethernet with unique MAC via RTL8211E PHY USB […]

Raspberry Pi VideoCore IV Boards Get an Unofficial Vulkan Driver Good Enough to Play Quake 3

The Raspberry Pi Foundation is collaborating with Igalia to work on everything related to graphics support for VideoCore VI GPU found in Raspberry Pi 4’s Broadcom BCM2711 SoC. This lead to OpenGL ES 3.1 conformance at the beginning of the year, and good progress with Raspberry Pi 4 Vulkan support. There’s no plan to work on an official Vulkan driver for earlier Raspberry Pi boards with VideoCore IV GPU, but since the Raspberry Pi Foundation released open-source VideoCore IV driver and documentation several years ago, it’s, in theory, possible for skilled developers to improve on it. That’s exactly what Martin Thomas, an NVIDIA engineer, has done in his spare time, and after two years of work, a Vulkan driver for Raspberry Pi VideoCore IV board – RPi-VK-Driver – has been released on Github. Pi-VK-Driver implements a subset of the Vulkan, and since it is not fully conformant to the standard […]

Checking Out Raspberry Pi OS 64-Bit on Raspberry Pi 4 8GB RAM

The Raspberry Pi 4 with 8GB RAM launched a couple of weeks ago together with the beta version of Raspberry Pi OS 64-bit. Note that you should currently use the 32-bit version of Raspberry Pi OS (previously known as Raspbian) as the 64-bit still has bugs and missing features, but I want to find out the current progress, so I installed raspios_arm64-2020-05-28/2020-05-27-raspios-buster-arm64.zip and had no problem to boot the board. Raspberry Pi OS 64-bit System Information After going through the setup wizard in the desktop environment to configure the language, time, networking, etc…, and make sure the OS is updated, I checkout some information:

pi@raspberrypi:~ $ cat /proc/cpuinfo

I do have a Raspberry Pi 4 Model B Rev 1.4 with 8GB Memory (revision: d03114), the image comes with a 64-bit Linux kernel:

and we do get a 64-bit rootfs.

CrowPi2 Raspberry Pi 4 Laptop Doubles as Electronics Learning Kit (Crowdfunding)

CrowPi2 Raspberry Pi 4 Laptop with Detachable Keyboard

CrowPi portable learning kit for Raspberry Pi 3 B+ and Pi Zero boards was launched in 2018. It comes with a 7″ display, several sensors, buttons, a breadboard, and more all packed in a small suitcase. Elecrow has now started a new crowdfunding campaign on Kickstarter to fund the second generation portable electronics learning kit: CrowPi2 which looks much more like a laptop than a suitcase found in the first model thanks to a large display, and a detachable keyboard placed on top of the electronic prototyping/learning area. It’s also more powerful thanks to the latest Raspberry Pi 4 SBC. CrowPi2 specifications: Compatible Raspberry Pi boards – Raspberry Pi 3B/B+, Raspberry Pi 4 Display – 11.6-inch 1920×1080 IPS screen Camera – 2MP camera Audio – Built-in microphone and stereo speaker; 3.5mm audio jack Keyboard – 2.4GHz detachable wireless keyboard (QWERTY only) with touchpad Sensors and Modules under the keyboard: Displays […]
