Octo4a app installs OctoPrint server on Android smartphones

Octoprint Android

Octoprint is a popular open-source 3D printer controller software that runs on Raspberry Pi boards, Orange Pi Lite SBC, Amlogic TV boxes, and other devices. But considering many people may already an older, perfectly working smartphones at home, FeelFree (Filip) decided to create the Octo4a project that install an Octoprint server on Android smartphones. It makes perfect sense since many smartphones come with a USB OTG interface that can connect to the 3D printer for control, while the touchscreen display is used for the user interface, and the camera to monitor your prints. SSH could be used to access the phone Octoprint server and change the settings manually. You can access the source code and APK files on Github. You’ll need to enable third-party apps in the settings before installing the app in order to install Octoprint on the phone. The only required permission is storage, except if you’d like […]

Orange Pi R1 Plus LTS is a cheaper dual GbE SBC with YT8531C Ethernet transceiver

It’s been a while since Shenzhen Xunlong Software released a new Orange Pi board. But the wait is over… sort of, as Orange Pi R1 Plus LTS is a low-cost version of Orange Pi R1 Plus SBC that replaced the Realtek RTL8211E PHY with a YT8531C Ethernet PHY that offers the exact same features but at a lower price. That means the new single board computer is still designed for headless operation, for example  a router or firewall, with a Rockchip RK3328 processor, 1GB RAM, dual Gigabit Ethernet, and a USB 2.0 port. Orange Pi R1 Plus LTS specifications: SoC – Rockchip RK3328 quad-core Cortex-A53 @ 1.5 GHz with Arm Mali-450MP2 System Memory – 1GB LPDDR3 RAM Storage – MicroSD card slot, 16 MB SPI flash Connectivity – 2x Gigabit Ethernet via YT8531C Ethernet PHY and RTL8153B USB 3.0 to Ethernet chip USB – 1x USB 2.0 port, 1x USB-C OTG […]

Android 12 on Raspberry Pi 4 – (Almost) everything works

Android 12 (AOSP) source code was released last month, and a developer took the opportunity to port Android 12 to the Raspberry Pi 4 single board computer and derivatives. More specifically, KonstaT created an unofficial build of LineageOS 19.0 for Raspberry Pi 4, Raspberry Pi 400 keyboard PC, and Compute Module 4 working on systems with at least 2GB of RAM. While it’s reserved for advanced users, the Android 12 build appears to work pretty well with most features supported including: Video HDMI display including CEC Touchscreen/multi-touch (USB touchscreens, Waveshare SPI touchscreens) Hardware-accelerated graphics (V3D, OpenGL & Vulkan) Audio HDMI, 3.5mm jack, USB microphones, Bluetooth speakers/headphones Audio DACs such as Hifiberry DAC+ Connectivity Ethernet WiFi including tethering Bluetooth including Bluetooth tethering GPS using external USB modules USB tested with USB mouse, keyboard, storage, etc… USB-C: ADB, MTP, PTP, USB tethering I/Os (GPIO, I2C, SPI) tested with Remote controls via external […]

Amlogic T972 multimedia networking SBC supports 4K V-by-One displays

We’ve seen plenty of Amlogic S-series TV boxes and SBCs over the years, but Amlogic also manufacturer T-series SoCs designed for televisions. Since there are relatively few TV manufacturers compared to TV boxes or board manufacturers we seldom read about those. But a few years ago, we noticed a TV box based on Amlogic T962E quad-core Cortex-A53 processor offering both HDMI input and output ports, and now Shenzhen Tomao just informed me they were offering an Amlogic T972 multimedia network SBC for digital signage applications with multiple HDMI inputs and a V-By-One display interface with support for up to 4K resolutions. Amlogic T972 SBC specifications: SoC – Amlogic T972 (or T962X2) quad-core Arm Cortex-A55 processor @ 1.98 GHz with Arm Mali-G31 MP2
 GPU with support for OpenGL ES 3.2, Vulkan 1.1 and OpenCL 2.0 System memory – 2GB or 4GB DDR4 Storage – 16GB eMMC flash, MicroSD card socket Display […]

Raspberry Pi inspired Intel SBC supports Myriad X AI accelerator, 5G connectivity

Axiomtek KIWI310 may look like a Raspberry Pi SBC but it packs an Intel Celeron N3350 processor, an M.2 slot with support for Myriad X AI accelerator, and the company also offer a HAT with 5G cellular connectivity. The single board computer also comes with up to 4GB LPDDR4 memory, up to 64GB eMMC flash, a Micro HDMI port, two USB 3.0 and two USB 2.0 ports, as well as the ubiquitous 40-pin GPIO header. Power options are also an improvement over your typical Raspberry Pi board with USB-C PD as well as LiPo battery support. Axiomtek KIWI310 specifications: SoC – Intel Celeron N3350 dual-core Apollo Lake processor @ 1.1 GHz / 2.4 GHz (Turbo) with Intel HD Graphics 500; 6W TDP System Memory – Up to 4GB (specs) or 8GB (YouTube video) LPDDR4 Storage – Up to 64GB eMMC flash, SPI flash for AMI BIOS Video & audio output […]

XPI-S905X3/S905X2 4K SBC with 2GB RAM sold for $35 and up

Geniatech has added two more single board computers to its XPI family with Raspberry Pi form factor. The Geniatech XPI-S905X2 and XPI-S905X3 boards are powered by respectively Amlogic S905X2 and S905X3/S905X4 quad-core processors, ship with 2GB RAM, and sell for $35 and up depending on the choice of processor and the presence of a wireless module. The company promotes each Raspberry Pi 3 lookalike as a “4K Single Board ARM PC” because of the 4K video playback capabilities or the Amlogic processors. Those boards provide an update to the earlier Amlogic S905X based XPI-S905X, and join Rockchip and NXP models. Geniatech XPI-S905X3/S905X2: SoC (one or the other) Amlogic S905X2 quad-core Cortex-A53 processor with Mali-G31 MP2 GPU Amlogic S905X3/S905X4 quad-core Cortex-A55 processor with Mali-G31 MP2 GPU System Memory – 2GB 1GB Optional) Storage – 8GB eMMC flash (option for 16GB or 32GB), MicroSD card slot Video & audio output – HDMI […]

Radxa CM3 Raspberry Pi 4 alternative was just introduced yesterday, but today, Pine64 SOQuartz Compute Module has just become available for $34.99 and up. Pine64 announced the Raspberry Pi Compute Module 4 compatible Rockchip RK3566 system-on-module (SoM) last June, and today the company/community launched three SOQuartz models with a wireless module and equipped with either 2GB, 4GB, or 8GB RAM.

Radxa CM3 – A drop-in Raspberry Pi CM4 alternative

Radxa CM3 is a system-on-module that offers an alternative to the Raspberry Pi CM4, with the same form factor allowing it to become a drop-in replacement, but switching from a Broadcom BCM2711 processor to a Rockchip RK3566 quad-core Cortex-A55 SoC. Radxa CM3 will work with existing carrier boards for the Raspberry Pi Compute Module 4, albeit some features such as dual HDMI are not available, instead, providing a single HDMI, but the module also offers extra features through an additional 100-pin board-to-board with interfaces such as SATA III and USB 3.0. Let’s compare Radxa CM3 specifications to the ones of Raspberry Pi CM4. Comparing Broadcom BCM2711 quad-core processor and Rockchip RK3566, as the Cortex-A72 may still be faster on some workloads despite the lower frequency, and some other workloads may be dramatically faster on RK3566, for example for those using Armv8 Crypto extensions missing on all Raspberry Pi, which we […]
