Raspberry Pi based Hyper Keyboard Pi & hgTerm Handheld PCs, and RasPi Arcade Stick

hgterm DIY Raspberry Pi Handheld Computer

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 […]

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 […]

Atomic Pi SBC is back with pre-orders on Amazon and Ameridroid

Atomic Pi single board board is probably the SBC with the best performance / value ratio on the market, so when we reported that Atomic Pi was available worldwide last month the 6,000 pieces available quickly ran out of stock. Many people suspect it was a limited product run from a previous project, and indeed Atomic Pi is most likely AAEON MF-001 board that was designed for Kuri robot designed for the now-defunct Mayfield Robotics. But we have some good news as Atomic Pi SBC does not appear to be a one-off sales getting rid of stock as it’s now back for pre-order on Amazon US and Ameridroid with shipping scheduled for the end of May. I won’t go through the whole specifications again but with an Intel Atom x5-Z8350 quad core processor, 2GB RAM, and 16GB flash, Atomic Pi board has hardware far more powerful than the similarly priced […]

Khadas VIM3 Amlogic S922X Board to Support M.2 NVMe SSD, WiFi 5, and Bluetooth 5 Connectivity

Ever since the Amlogic S922X powered ODROID-N2 SBC launched last March, I keep reading praise for the processor and board which both deliver great performance at a relatively low price. Hardkernel was the only company that sold such a board so far, but this is about to change with some competition coming from Shenzhen Wesion with their upcoming Khadas VIM3 board that includes 2 to 4GB RAM, 16 to 32GB eMMC flash storage, a wireless module, support for M.2 NVMe SSD, and more. Even though more are planned in the future, two Khadas VIM3 models have been announced so far – Basic and Pro – with the following preliminary specifications: SoC – Amlogic S922X hexa-core processor with 4x Arm Cortex-A73 and 2x Cortex A53 cores, Arm Mali-G52 MP4 GPU, built-in Cortex-M4 core for “always-on” processing MCU – STMicro STM8S003 with Programmable EEPROM for power management, customizations, and boot media configuration […]

How One Line of Code Tripled Allwinner A20 SATA Write Performance

If you’ve been following this blog long enough, you may remember that all linux-sunxi community work aiming at improving u-boot and Linux software support on Allwinner processors started with Allwinner A10 processor found in MeLE A1000 TV box back in 2012, which at the time provided an interesting alternative to Raspberry Pi board that was in short supply at launch time and several months after. One of the most interesting feature found in Allwinner A10 single core Arm Cortex-A8 processor was its SATA interface, and Allwinner A20 was announced a few months later with a dual core Cortex-A7 processor and virtually the same peripherals as Allwinner A10, including SATA. However when I tested CubieTruck board connected to a mechanical drive, I noticed sequential SATA performance was fine for reads (~180MB/s), but writes were fairly slow at around 36 MB/s. Other people complained about it, and some looked into it, and […]

Volumio Motivo is a Gorgeous Audio Streamer Powered by SOPINE A64 SoM

Volumio is a well-known Linux based open source music player for Raspberry Pi, UDOO, Cubox-I, Beaglebone Black, and other single board computers. Some companies even made audiophile boards with support for Volumio including Khadas Tone high-resolution audio board for VIM/VIM2 SBC’s, and the tiny VoltaStream ZERO following Raspberry Pi Zero form factor. But Volumio team has decided to make their own hardware with Motivo, an awesomely looking audio streamer designed in collaboration with Yottamusic engineering firm, and Design Narratives industrial design company. Motivo was introduced at High-End Munich, the world’s biggest Hi-Fi trade fair, and Pine64 posted some photos in a tweet claiming it was powered by their SOPINE A64 system-on-module. The full details about the device have not been published at the time of writing, but we can still derive some of Volumio Motivo specifications and key features from the photos and a few bits of public information: System-on-Module […]

Roshambo Retro Gaming Console Kit Features Rock64 or RockPro64 Board

Recalbox, Lakka TV, Retro Arena, and Batocera are some of the retro gaming distributions optimized to run on development boards. You can install those by yourself, and enclose the board is any case, but if you want something more fancy, Cloud Media is now selling Roshambo retro gaming kit based on Rock64 (RK3328) or RockPro64 (RK3399) SBC’s. Roshambo and RoshamboPro retro gaming kits are compatible with respectively Rock64 and RockPro64 boards, come with a shell with carrier board, power supply, cooling fan (Pro model only) and support cables.
