Upcoming RTD1619 Media Players – Dune HD Pro 4K II, Zidoo Z9X, and Zidoo X

Realtek RTD1619 hexa-core Cortex-A55 media SoC was first spotted in 2018 in the Linux source code. Since no products had been launched based on RTD1619, I had mostly forgotten about the processor until I wrote about RTD1395 powered Dune HD RealBox 4K. I was then informed about the upcoming Dune HD Pro 4K II, and a quick search reveals Zidoo is also working on its own RTD1619 media players with Zidoo Z9X and Zidoo X models. Dune HD Pro4K II Specifications: SoC – Realtek RTD1619 hexa-core Cortex-A55 processor with Mali-G51 Bifrost GPU System Memory – 4 GB RAM Storage – 32 GB flash, MicroSD slot, external SATA HDD (data + power) Video Output – HDMI 2.0b up to 4Kp60 HDR, 3.5mm A/V connector for composite Video Input – HDMI 2.0 input for PiP or recording Audio Output – optical S/PDIF, digital audio via HDMI, analog stereo audio via A/V connector Video Playback 4Kp60 HDR/HDR10+ with 10-bit H.265 and VP9 profile-2, …

Banana Pi BPI-M4 SBC Gets 2GB RAM, Sells for $43

First unveiled in February 2019, Banana Pi BPI-M4 is a single board computer based on Realtek RTD1395 quad-core Cortex-A53 4K media processor and following Raspberry Pi 3B+ form factor pretty closely. BPI-M4 officially launched in June 2019 for just $38 with 1GB DDR4 RAM, but despite the 2GB RAM option being listed in the specification, the 2GB version of the board was not available, at least on Aliexpress. The good news is that Banana Pi BPI-M4 with 2GB RAM has just started selling for $43 plus shipping on Aliexpress, or in Taobao if you based in China. Banana Pi BPI-M4 2GB specifications: SoC – Realtek RTD1395 quad-core Arm Cortex-A53 processor with Mali-470 MP4 GPU System Memory – 2GB DDR4 RAM Storage – 8GB eMMC flash, micro SD slot up to 256GB, M.2 NVMe SSD Video Output – HDMI 2.0b port up to 4K @ 60 Hz, HDR support Video Decode – 4K2K 60fps H.265 and VP9, 4K2K 30 fps H.264, …

Seeed IoT Button for AWS Brings Back Amazon Dash Button to Life for Developers

Amazon introduced $5 dash buttons in 2015 to let consumers purchase regular items such as washing powder by simply pressing a button. Some people hacked them for other purposes, for instance as WiFi logging buttons, but the company eventually stopped selling the buttons in February 2019 and fully killed those at the end of August. Seeed Studio is bringing back Amazon Dash button to life in some ways, with the Seeed IoT Button For AWS Wi-Fi-based, programmable button that deploys the AWS IoT 1-Click service. Seeed IoT Button for AWS hardware specifications: MCU – Dual-core MCU with 20MHz Cortex M0 and 200MHz Cortex M4F (Very likely Realtek RTL8720DN Wireless MCU) Storage – 4MB flash Connectivity – Dual-band Wi-Fi 4 802.11 a/b/g/n (2.4GHz & 5GHz) and Bluetooth 5.0 LE USB – 1x USB Type-C port for charging Misc – Button good for 100,000 cycles, 3x LEDs (red, green, blue) Power Supply 5V via USB-C port Battery – 3.6V Li-ion 18650 Rechargeable …

$11 DIGOO DG-R611 WiFi Repeater Comes with Two External Antennas

Low-cost WiFi routers such as A5 V11 mini router have been around for many years. The cheaper ones are usually powered by a USB charger sold separately, and support 2.4 GHz WiFI with a single antenna. But I’ve just noticed DIGOO DG-R611 WiFi repeater with support for dual-antenna, data rate up to 300 Mbps, and integrated power supply. It is sold for under $11 on Banggood and Aliexpress, and may be worth a closer look.     DIGOO DG-R611 specifications: SoC – Realtek RTL8196E RISC processor @ 400 MHz System Memory – TBD Storage – TBD Networking Wired – 10/100M Ethernet port Wireless 2.4 GHz 802.11b/g/n WiFi 4 up to 300 Mbps Two 2dBi antennas  Wireless Transmit Power – 20dBm(MAX EIRP) Repeater, Access Point (AP), or Media bridge modes supported  Wireless Security – 64/128-bit WEP, WPA/WPA2, WPA-PSK/WPA2-PSK (TKIP/AES) Power Supply – Integrated 110-230V with US, EU, or UK plug Dimensions – 7 x 7 x 7.5 cm excluding antennas Temperature …
