Nuvoton NUC970 ARM9 Microprocessor Gets Mainline Linux Support

As I checked out the latest email on the ARM Linux kernel mailing list, one thread somehow caught my attention: “[PATCH v2 00/10] ARM: NUC900: Add NUC970 SoC support” with the following introduction: This patch series added Nuvoton new SoC NUC970 development board support, this nuc970 belongs to nuc900 series, but many features are not compatible with old nuc900 SoCs like nuc910, nuc920. I could not quite remember ever having heard about Nuvoton, and it turns out it’s a fairly recent Taiwan company, founded in 2008 as a spinoff and fully own subsidiary of the better known Winbond Electronics. Their website shows ARM Cortex M0/M4 & 8051 micro-controllers, as well as ARM7 and ARM9 micro-processors, and some other application specific audio and video SoCs. But when I checked for MUC970 I could not find anything on their website, even in NUC900 series page. But Google came to the rescue and […]

ARNU Box Mach 10 64-bit Pure Linux TV Box Review

In part 1 of ARNU Box Mach 10 64-bit Pure Linux review, I listed the specifications, and took some pictures of the Amlogic S905 based TV box, and its board. I’ve now completed testing of this Kodi Linux media player, going though setup and add-ons, and see how it works compared to ARNU Box Mach 10 Pure Linux based on Amlogic S812 processor. Setup, Cloudword and Configuration The setup part is basically the same as on the previous model, but I’ll go through it again. Please ignore the vertical white line on the TV in the photos below, as it’s just due to my 18 months old LG 42UB820T 4K UHD television being partially broken, and out of warranty. The boot will typically take 30 seconds, but the first time, you’ll go through ARNU Box Setup Wizard. You could skip it in theory, but it’s still a good idea to […]

Star Cloud PCG03U Bay Trail Ubuntu mini PC with 2GB RAM, 64GB Storage Sells for $90

Last year, I reviewed MeLE PCG03 mini PC with Windows 8.1. and later upgraded it to Windows 10, but the company has now started to launch Ubuntu based TV sticks and mini PCs, under their new Star Cloud brand, with for example Star Cloud PCG02U TV stick, and now they’ve just launched Star Cloud PCG03U running Ubuntu 14.04 for $89.59 shipped on Aliexpress. Star Cloud PCG03U specifications: SoC – Intel Atom Z3735F “Bay Trail” quad core processor @ 1.33 GHz / 1.83 GHz) with Intel HD graphics System Memory – 2 GB DDR3L Storage – 64 GB eMMC + SD card slot (up to 512 GB) Video Output – HDMI 1.4, and VGA Audio I/F – HDMI, 3.5mm earphone jack Connectivity – 10/100M Ethernet, 802.11 b/g/n Wi-Fi up to 300 Mbps, and Bluetooth 4.0 USB – 3x USB 2.0 host ports (The specs mention 1x USB 3.0 port, but it […]

Smaller & Faster than Raspberry Pi Zero: Meet NanoPi NEO ARM Linux Development Board

Raspberry Pi Zero has two noticeable attributes compared to other Raspberry Pi boards: it’s smaller and it’s cheaper. FriendlyARM has now designed another model for their NanoPi family, that about 12% smaller, although not quite as thin at all due to its Ethernet jack and USB connector, and much faster than Raspberry Pi Zero, with NanoPi NEO board powered by Allwinner H3 quad core processor. NanoPi NEO specifications: SoC – Allwinner H3 quad core Cortex A7 @ 1.2 GHz with an ARM Mali-400MP2 GPU up to 600 MHz System Memory – 256 or 512 MB DDR3 Storage – micro SD card slot Connectivity – 10/100M Ethernet USB – 1x USB 2.0 host ports, 1x micro USB OTG port, 2x USB via headers Expansion headers 24-pin header with I2C, 2x UART, SPI, PWM, and power signals 12-pin header with 2x USB, IR pin, microphone and Line OUT signals Debugging – 4-pin […]

RisingHF IoT Discovery is a LoRaWAN Evaluation Kit for Raspberry Pi

There are many current and upcoming long range low power wireless protocols for the IoT, but this morning I learned that South Korea launched a LoRa network (aka LoRaWAN), after another launch in the Netherlands earlier this year. While there are also some LoRa hobbyist kits such as LoraONE and LoPy being worked on, I decided to look on Aliexpress, but only got two products were listed: a LoRaWAN temperature and humidity sensor, and a LoraWAN USB modem. Both of them are made by a company called RisingHF. Among the products offered by the company, there’s a potentially interesting development kit called RisingHF IoT Discovery with the following components: 1x Raspberry Pi board 1x RHF0M301 LoRa Gateway based on Semtech SX1301 1x RHF4T002  adapter for Raspberry Pi and RHF0M301 1x RHF3M076 LoRaWAN USB AT Modem End point to connect to computer. It operates at 434MHz, 470MHz,868MHz, and 915MHz 3x RHF76-052 […]

AOMedia AV1 is a Royalty-free, Open Source Video Codec Aiming to Replace VP9 and Compete with H.265

The Alliance for Open Media, or AOMedia, is a new non-profit organization founded in 2015 by Amazon, Cisco, Google, Intel Corporation, Microsoft, Mozilla, and Netflix, and more recently joined by AMD, ARM, and NVIDIA, whose first project is to develop AV1 royalty-free and open video codec and format to provide an alternative to H.265 / HEVC, and a successor to VP9. The project is a team effort combining teams working on Daala, Thor, and VP10 video codecs, and while AFAIK, AV1 specifications have not been released yet (target: Q1 2017), the organization has already released an early implementation of AV1 video decoder and encoder under the combination of an BSD-2 clause license and the Alliance for Open Media Patent License 1.0 , which can be found on googlesource.com. So I’ve had a quick my myself following the instructions, by first downloading one uncompressed YUV4MPEG sample:
