Obvious is an App Store for Embedded Devices

Obvious app store embedded devices

Mobile devices have gotten their own app stores for more than 10 years already, with Google Play for Android and Apple App Store for iPhones and iPads. Linux powered IoT devices – usually gateways – also got their own app stores with branded Ubuntu app stores relying on Ubuntu Snaps,  although I’m not sure they are widely used. However, low power embedded devices usually based on microcontrollers did not get their own app store, and Obvious aims to fill this gap with the Obvious platform, an app store for embedded devices, which enabled after-sales features and upgrades. Obvious app store is currently in Beta and works exclusively with Nordic Semi based products at this stage. We don’t know an awful lot about the services, except it will enable a new revenue stream for providers of low power wireless IoT devices. Some benefits listed by the company include: Untapped resources –  Spare CPU cycles, an extra I/O port or an unused …

ANAVI Thermometer WiFi Board is Designed for Home Automation (Crowdfunding)

ESP8266 Thermostat

ANAVI Technology launched several open source hardware boards for the Raspberry Pi and ESP8266 maker communities in the past, starting with RabbitMax Flex home automation HAT for Raspberry Pi, and several others including ANAVI Light Controller ESP8266 board to control LED strips. All boards are designed with KiCad opensource EDA software, and I’ve tested several already such as ANAVI Infrared pHAT or ANAVI Light Controller, and found documentation to be very good and easy to follow. The company has now launched another ESP8266 board with ANAVI Thermometer that allows you to monitor temperature and humidity, effectively acting as a thermostat for home automation.

Radxa Rock Pi 4 Review – Part 1: A First Look at RockPi 4B Performance Set

Rock Pi 4 Review

Hey, Karl here with another RK3399 board. This one is by Radxa and is called the Rock Pi 4. There are 2 main variants to this board and I was shipped the B version “performance set” which includes a power supply, heatsink, and acrylic case. Also shipped was 16gb eMMC 5.1 module, eMMC flashing board, and USB-TTL debug cable. It looks like the difference is the B version has AC wifi and GbE LAN with PoE support with a hat. The A version only has GbE.

ClearFog CX LX2K Networking Board is Powered by NXP LX2106A 16-core Processor

ClearFog CX LX2K

SolidRun started their ClearFog family of networking boards back in 2015 with Marvell ARMADA based ClearFog Pro board exposing 7 Gigabit Ethernet ports, an SFP cage, mPCIe/mSATA sockets, and more. Since then the company has launched several other ClearFog boards with small variation in the name with the latest being ClearFog CX 8K equipped with a COM Express module based on Marvell ARMADA A8040 quad-core Arm Cortex A72 processor. Today I was made aware that the company leveraged of the flexibility of having a COM Express module by offering a more powerful version of the board – ClearFog CX LX2K – powered by NXP LX2160A networking processor with 16 Arm Cortex-A72 cores, 100GbE support, 24x PCIe Gen4 lanes, and more. The rest of the specifications are pretty much the same since the COM Express carrier board – pictured above – remains the same: COM Module – CEx7 LX2K module with NXP LS2160A 16-core Arm Cortex A72 processor @ up to …

Rockchip RK1808 Cortex-A35 NPU Delivers up to 3.0 TOPS

RK1808 NPU AIoT Solution

Rockchip RK3399Pro was expected to be the first processor from the company featuring an NPU (Neural Processing Unit) to accelerate artificial intelligence workloads, but eventually went through a redesign, and the community found it gave birth to RK1808 NPU by looking at a device tree file in the Linux kernel. Rockchip has now made the NPU official at CES 2019, and we now know a little bit more. Here are the specifications shared by the company: Dual-core Arm Cortex-A35 CPU NPU computing performance up to 3.0TOPs supporting INT8/INT16/FP16 hybrid operation VPU supporting 1080P video codec Built-in 2MB system-level SRAM Display – MIPI/RGB video output Camera – MIPI/CIF/BT1120 Camera video signal input with built-in ISP Audio Microphone array support with hardware VAD function for low-power monitoring and far-field wake-up Audio output I/O PWM/I2C/SPI /UART USB3.0/USB2.0 PCIe interface Support for Gigabit Ethernet and external WiFi/Bluetooth modules Manufacturing – 22nm FD-SOI process It shares many similar functions as standard media SoCs, but it …

NXP Immersiv3D Enables DSP-Free Dolby Atmos & DTS:X Audio Systems

NXP Immersiv3d audio reference design

High-fidelity audio systems such as soundbars, smart speakers, and AV receivers have traditionally relied on DSPs (Digital Signal Processors) to deliver low-latency audio processing, and enable audio and video synchronization. DSPs add to the cost of the overall design however, and with Immersiv3D technology, NXP has leveraged Arm Cortex-A53 and M4 cores in their NXP i.MX 8M Mini processor to completely remove the need for DSP in audio systems, shaving the BoM cost by up to 20%  according to an article on EETimes. Immersiv3D also enables immersive audio support with Dolby Atmos and DTS:X, advanced audio pre/post processing, advanced features like voice control for the smart home. Immersiv3D audio solution was designed to help OEMs to bring to market affordable consumer audio devices with Dolby Atmos and DTS:X, and beside the audio processing software, NXP is also offering an Immersiv3D audio reference design to help them delelop sound bars based on the solution. The press release further explains: The NXP …
