Orange Pi 800 Keyboard PC – A Raspberry Pi 400 alternative powered by Rockchip RK3399

Raspberry Pi 400 Keyboard PC alternative

There’s now a Raspberry Pi 400 alternative with the Orange Pi 800 Keyboard PC that offers a very similar design, but it is powered by a Rockchip RK3399 hexa-core Cortex-A72/A53 processor. Like the Raspberry Pi model, the Orange Pi 800 comes with 4GB RAM, Gigabit Ethernet, dual-band WiFi 5 and Bluetooth 5.0, two USB 3.0 ports, and one USB 2.0 port, but it also adds 64GB on-board flash storage and features one full-size HDMI port capable of 4Kp60 resolution plus a VGA port, instead of two micro HDMI ports. Orange Pi 800 specifications: SoC – Rockchip RK3399 hexa-core big.LITTLE processor with 2x Arm Cortex-A72 cores up to 1.8GHz, 4x Arm Cortex-A53 cores up to 1.4GHz, and an Arm Mali-T860MP4 GPU System Memory – 4GB LPDDR4 Storage – 64GB eMMC flash, microSD card slot Video Output HDMI 2.0 port up to 4Kp60 VGA port up to Full HD resolution Audio 3.5mm […]

UP 4000 x86 SBC review – Part 1: Unboxing and first boot

AAEON UP 4000 is a compact Apollo Lake single board computer that’s about the size of a business card or a Raspberry Pi designed for automation, robotics, digital signage, and other space-constrained applications that may benefit from an x86 processor. The company already published some Phoronix benchmarks comparing the UP 4000 SBC against Raspberry Pi 4, NVIDIA Jetson Nano, and the original UP board, but since nothing beats third-party evaluation, AAEON sent a review sample to CNX Software for additional testing. UP 4000 SBC unboxing There are several variants of the board, and I received the UP-APL03X7F-A10-0464 SKU with 4GB RAM, 64GB eMMC flash, and an Intel Atom x7-E3950 quad-core processor. The package includes the board together with a multilingual safety manual that explains you should not immerse the board underwater and should avoid walking on it :). A 12V/5A power supply was also included separately. The power cord was […]

Chromecast with Google TV (HD) features Amlogic S805X2 CPU with AV1 video support

Google has launched the new Chromecast with Google TV (HD) powered by an Amlogic S805X2 quad-core Cortex-A35 CPU that offers a cheaper alternative to the Chromecast with Google TV (4K) that is limited to 1080p60 resolution, instead of the 4Kp60 video output supported by the Amlogic S905X3 model. While the processor is slower, the system comes with less memory (1.5GB vs 2GB), and only supports 1080p60, it supports the more efficient AV1 video decoding and as well as A/B partitions for seamless updates since the firmware does not need to be downloaded to the internal storage before the Chromecast with Google TV (HD) specifications: SoC – Amlogic S805X2 quad-core Cortex-A35 processor with Mali-G31 MP2 GPU, 1080p60 H.265, H.264, VP9, AV1 video decoder System Memory – 1.5GB RAM Storage – 8GB eMMC flash with support for “virtual A/B updates with compression“ Video output – HDMI up to 1080p60 with HDR support […]
