Khadas VIM2 v1.4 SBC Gets Bluetooth 5, Thermal Improvements, a Larger SPI Flash

Khadas VIM2 Thermal Design

Announced in summer of 2017, Khadas VIM2 was the first Amlogic S912 development board, and I had the chance to review the board with a dual DTV tuner add-on board shortly after launch, eventually explaining how to use VIM2 as a live TV streaming server in Android. Shenzhen Wesion has however recently launched Khadas VIM2 v1.4 with various improvements they neatly describe in a PDF document. Before I go through the main changes, I’d like to remind readers there are three versions of Khadas VIM2 (v1.2) boards: VIM2 Basic – 2GB DDR4, 16GB eMMC flash, Ampak AP6356S wireless module with 802.11 b/g/n/ac WiFi 5, and Bluetooth 4.1 connectivity VIM2 Pro – 3GB DDR4, 32GB eMMC flash, Ampak AP6359SA wireless module with 802.11 b/g/n/ac with RSDB and Bluetooth 4.2 connectivity VIM2 Max – 3GB DDR4, 64GB eMMC flash, Ampak AP6359SA wireless module with 802.11 b/g/n/ac with RSDB and Bluetooth 4.2 connectivity One of the first change in VIM2 v1.4 is the …

HiSilicon Hi3559A Board Enables Smart 8K Camera Development

Hi3559A 8K camera board

HiSilicon Hi3559A 5-core Arm Cortex A73/A53 camera processor was announced in 2017 with support for 8K 30fps or 4K 120fps video recording, as well as an integrated dual core neural network accelerator (NNA). It should not be confused with the earlier Hi3559 4K 30 fps processor, or the newer Hi3559C that looks to be the same as Hi3559A without the NNA. Nevertheless, today I was lead to check about Hi3559A processor once again, and I could not find any camera that you can just buy and use today. I still found some upcoming Hi3559A products with OBSBOT Tail AI camera offered for as low as $509 on Kickstarter (delivery scheduled for April 2019), one 4K  120fps OEM? camera from GKuvision, as well as an HiSilicon Hi3559A development board for 8K camera applications, which I’ll look into more details in this blog post. HI3559AV100DMEB specifications: SoC – Hisilicon Hi3559A V100 with 2x Arm Cortex A73 cores @ 1.8 GHz, 2x Arm …

DIP-Sized uChip Arduino Zero Compatible Board Loves Your Breadboard (Crowdfunding)

uchip breadboard-friendly arduino board

Most so-called breadboard-friendly boards that can easily be inserted into a breadboard often leave only one or two rows to play with on each side. This may suitable in many cases, but some people really want to use as many rows as possible, and come up with a solution using 90 degrees headers with 0.3″ spacing between them, just like 0.3″ wide chips do, and allowing the use of 4 rows on each side of the board. It does the trick, but this is not a standard solution, requires some bending of the headers, and covers part of the board so it’s not really ideal. A better way would be for somebody to design a narrow board using headers with 0.3″ spacing, and that’s exactly what Itaca Innovation has done with their Arduino Zero compatible uChip board designed in a 16-pin DIP package. uChip specifications: MCU – Microchip SAMD21 Arm Cortex M0+ MCU clocked @ 48 MHz (Arduino Zero Compatible) …

$30 Arch Mix Development Board Features NXP i.MX RT1052 Crossover Processor

Arch Mix

NXP i.MX RT Arm Cortex-M7 crossover processors are supposed to fill the gap between microcontrollers and more powerful application processors thanks to real-time capabilities, and a higher CPU frequency. We’ve already covered several i.MX RT1050 series platforms including NXP’s own evaluation board and Forlinx OK1052-C development kit comprised of a carrier board and an i.MX RT1052 system-on-module. But if you’d like to experiment with NXP i.MX RT processor using a cheaper, smaller, and easier to purchase development platform, Seeed Studio has started to sell Arch Mix development board for $29.90 plus shipping.

MapleBoard MP130 Allwinner H3 Board Almost Follows 96Boards CE Extended Form Factor

MapleBoard MP130

There are so many Allwinner H3 SBCs or development boards that new ones are often uninteresting, but with the release of Linux 5.0, I discovered a new board that I had never heard of: MapleBoard MP130. The board is equipped with 1GB RAM, Fast Ethernet, four USB ports, and various I/O expansion headers. But the form factor looked familiar, and it seems compliant with 96Boards CE Extended, except for some reasons they decided to swap the low speed and high speed connectors, so I doubt the board is compatible with any of the 96Boards mezzanines. MapleBoard MP130 specifications: SoC – Allwinner H3 quad core Arm Cortex-A7 processor at up to 1.3GHz with Mali-400MP2 GPU System Memory – 1GB DDR3L 1600 MHz Storage – 8GB eMMC 4.41 flash, microSD slot Video Output – HDMI 1.4 output with HDCP1.2 Connectivity – 10/100Mbps Ethernet Audio 2-ch 92dB ADC, 2-ch 100dB DAC, I2S/PCM Interface,  32-bit 8KHz ~ 192KHz Input – Stereo line-in phone jack …
