Cool Pi 4 Model B – A much faster alternative to Raspberry Pi 4 SBC

Cool Pi 4 Model B

Cool Pi 4 Model B is a powerful alternative to Raspberry Pi 4 SBC with mostly the same form factor and interfaces but equipped with a Rockchip RK3588S octa-core Cortex-A76/A55 processor that will run circles around the Broadcom BCM2711 SoC found in the Raspberry Pi board. We’ve already reviewed Rockchip RK3588/RK3588S single board computers and mini PC such as Rock 5B, Khadas Edge2 Pro, and Mekotronics R58, and we were impressed by the performance, but if you prefer to have such a board in Raspberry Pi 4 form factor, then the Cool Pi 4 Model B might be for you. Cool Pi 4 Model B specifications: SoC – Rockchip RK3588S octa-core processor with 4x Cortex-A76 cores @ up to 2.4 GHz, 4x Cortex-A55 cores, an Arm Mali-G610 GPU with OpenGL ES 3.2,  OpenCL 2.2, and Vulkan 1.1 support, 8Kp60 video decoder for H.265/AVS2/VP9/H.264/AV1 codecs, 8Kp30 video encoder, and a 6 […]

Sipeed Maix-III devkit features AXERA AX620A SoC for AI vision applications

Maix III Board

Sipeed Maix-III development kit is composed of a core board equipped with AXERA AX620A AI processor and a carrier board exposing several interfaces such as Ethernet, USB, and camera connectors. resources. As noted in our earlier article about the AXERA AX620A chip, it is a  quad-core Arm Cortex-A7 chip with an NPU offering a maximum of 14.4 TOPS @ INT4 or 3.6TOPSs @ INT8, and as such, this development board mainly targets AI vision applications. The board is an upgrade to the earlier Speed Maix II with an Allwinner V831 processor. Thanks to the low power consumption of the AXERA AX620A SoC, the Sipeed Maix-III board can be powered directly through its USB port as the system consumers 5W (5V@1A) with the carrier board, the system-on-module, WiFi, Ethernet, a camera, and a 5-inch display. Using the display does not require am additional heatsink or fan, nor does it require an […]

Giveaway Week – Mekotronics R58 mini PC

Mekotronics R58 USB ports

Let’s end Giveaway Week 2022 with a bang, and more exactly a rather powerful Rockchip RK3588 mini PC: Mekotronics R58 (mini). The device comes with 8GB RAM and 64GB flash storage, two 8K capable HDMI 2.0 output ports, one DisplayPort output,  one HDMI input, Gigabit Ethernet and WiFI 6 connectivity,  as well as a few USB 3.0/2.0 ports, plus support for a SATA drive. I reviewed the Rockchip RK3588 mini PC with Android 12 last July, and I was impressed by the CPU and GPU performance, 4K video playback capabilities, except for AV1 which was not stable at the time, and support for HDMI audio passthrough. Android 12 was quite stable at that early stage as well. Some downsides included the lack of a useful HDMI input app and USB 3.0 performance that could be improved. I always test samples before adding them to the giveaway, and I initially thought […]
