SDMC DV8919 Amlogic S905X4 Android TV 10 TV Box Supports AV1 Decoding

We’ve previously covered several TV box & set-top box SoCs with support for the royalty-free AV1 video codec including Broadcom BCM7218X SoC, and Amlogic S805X2, S905X4, and S908X processors. But so far, apart from an AV1 demo on the RTD1311/RTD1319 development board (Pymparticle EVB?), and new about Technicolor Jade STB, I had not really seen AV1-capable TV boxes so far. SDMC DV8919 appears to be the first Amlogic S905X4 TV box on the market and one of the first running the recently released Android 10 on Android TV OS. SDMC DV8919 specifications: SoC – Amlogic S905X4 quad-core Arm Cortex-A55 processor @ up to 2.0 GHz with Arm Mali-G31MP2 supporting OpenGL ES3.2, Vulkan 1.1 and OpenCL 2.0 System Memory – 2GB DDR memory (options: 1GB or 4GB) Storage – 8GB eMMC flash (options: 16GB, 32GB, 64GB), MicroSD card slot Video Output – HDMI 2.1 up to 4K @ 60+Hz with CEC […]

Project Connected Home over IP (CHIP) Working Group is Backed by Google, Apple, Amazon, and the Zigbee Alliance

Amazon, Apple, Google, and Zigbee Alliance have partnered to create Project Connected Home over IP (CHIP) working group aiming to develop a royalty-free, Smart Home standard to increase compatibility among products, and with security at the forefront. The new standard will be separate from Zigbee 3.0 / Pro, and Zigbee Alliance board member companies such IKEA, Legrand, NXP Semiconductors, Resideo, Samsung SmartThings, Schneider Electric, Signify (formerly Philips Lighting), Silicon Labs, Somfy, and Wulian will also join the CHIP working group and contribute to the project. The standard specified by Project Connected Home over IP will rely on existing technology from the networking layer including TCP/UDP transport protocol, IPv6 network and various physical & media standards such as WiFi, Ethernet, Bluetooth LE, Cellular, 802.15.4 and others. Instead, it will define what happens at the application layer level with the following points of focus: End-to-end data security and privacy among in-home and […]

RAK7244 LoRaWAN Developer Gateway Combines Raspberry Pi 4 with LoRa HAT, Optional 4G LTE Connectivity

After launching RAK831 Lite LoRaWAN gateway based on Raspberry Pi 3 board in 2018, RAK Wireless introduced Pilot Gateway Pro RAK7243 gateway with the more recent Raspberry Pi 3B+ SBC earlier this year. But with the launch of Raspberry Pi 4 last June, the Raspberry Pi 3B+ has become much harder to procure, so RAK has now launched an updated LoRa gateway featuring Raspberry Pi 4 SBC together with the company’s RAK2245 Pi Hat Edition LoRaWAN gateway concentrator module. RAK7244 LoRaWAN Developer Gateway specifications: SBC – Raspberry Pi 4 Model B with 2GB RAM Connectivity LoRa RAK2245 Pi Hat LoRaWAN gateway concentrator module with 1x SX1301 baseband processor, 2x SX125x Tx/Rx front-ends LoRaWAN v1.0.2 support Support for 8 channels and spreading factors SF7 to SF12 Bands – 433MHz, 470MHz, 865MHz, 868MHz, 915MHz, 920MHz, 923MHz Tx Power: 27 dBm Max RX Sensitivity: -139dBm Cellular – Optional 4G LTE support via RAK2013 […]

ANAVI Miracle Controller WiFi Board Drives Addressable LED strips (Crowdfunding)

Last year, we wrote a tutorial showing how to control an RGB LED strip Control ANAVI Light ESP8266 controller. The board only works with standard non-addressable 12V LED strips however, and Leon ANAVI received requests to support 5V and 12V addressable LED strips such as NeoPixels, WS2811, WS2812, or TM1804. So he updated ANAVI Light Controller design and has now launched a new open-source hardware certified board based on ESP8266 WiFi chip: ANAVI Miracle Controller. ANAVI Miracle Controller specifications: MCU – Espressif Systems ESP8266 Tensilica L106 32-bit processor Connectivity – Wi-Fi 4 802.11 b/g/n LED Strips Support – Up to two 5V or 12 V addressable LED strips; Supported models include WS2812, WS2812B, WS2811, TM1804, etc. (LED strip chipsets supported by the FastLED library) Expansion 4x I2C header for mini OLED display, sensors, and others 4-pin “GPIO” header with 1x GPIO, GND, 3.3V, and 5V signals Misc – Reset button, […]

Raspberry Pi Power Management HAT Adds RTC, Battery Management, Software On/Off

If your Raspberry Pi project runs on battery, but may not need to be turned on 24/7 in order to lower power consumption, you’d have to find a way to schedule on and off times, and power off the board cleanly either when the battery is almost depleted, or your timer requires it There’s no built-in support for this in any of the Raspberry Pi boards, but Waveshare Power Management HAT can help you do just that since it adds an RTC, and enables software-controlled power timers and battery monitoring via an Arduino compatible ATmega328 MCU. Power Management HAT specifications: MCU – Microchip ATmega328P-AU MCU Storage – CAT24C32 EEPROM USB – 1x micro USB port for serial communication via CP2102 UART to TTL chip RPi Interface – 40-pin Raspberry Pi GPIO header Misc NXP PCF8523 RTC & calendar chip + CR1220 battery holder DEBUG switch (9) to either: Power directly […]

Nebula Cosmos Max 4K Video Projector is Powered by Amlogic T962X2 Processor (Crowdfunding)

Cosmos Max 4K Projector with Amlogic T962X2

Amlogic recently launched its first Cortex-A55 processors for TV boxes with S905X3, S905Y3 & S905D3 quad-core processors, but as noted by one commenter Amlogic already had some other Cortex-A55 processor specifically designed for TVs and projectors: T950X2 for full HD systems, and T962X2 for 4K UHD systems. Most smart TVs and projectors don’t advertise which chip they are using internally but I’ve just come across Anker Nebula Cosmos Max 4K home theater/video projector featuring Amlogic T962X2 processor. Based on the illustration below they also have a Full HD model based on the same processor. But I’ll focus on the 4K model in this post. Anker Nebula Comos Max key features & specifications: SoC – Amlogic T962X2 quad-core Cortex-A55 processor @ 1.9 GHz with Arm Mali-G31MP2 GPU System Memory – 2GB RAM Storage – 16GB eMMC flash Projector 0.47″ DMD chip 4K UHD resolution (3840×2160) 30″ to 150″ display 1500 ANSI […]
