AYN Odin – A Dockable portable game console offered with Snapdragon 845 or Dimensity 900 (Crowdfunding)

AYN Odin is a 6-inch portable game console powered by Qualcomm Snapdragon 845 or MediaTek Dimensity 900 processor and offered with an optional dock with an HDMI port to connect it to a large screen, various ports for controllers, and even a 2.5-inch SATA bay. It offers a much more powerful experience, a larger display, a more recent Android 10/11 OS, and better multiplayer abilities than the Amlogic S905D3 powered Powkiddy A20 portable game console we have just covered. Three models of the Odin are offered with the Lite, Base, and Pro model differing in terms of processors, and/or storage and memory: SoC Odin Lite – MediaTek Dimensity 900 octa-core processor with 2x Cortex-A78 cores @ 2.4 GHz, 6x Cortex-A55 cores @ 2.0 GHz, Mali-G68 MC4 GPU Odin Base/Pro – Qualcomm Snapdragon 845 octa-core processor with 4x Kryo Gold (Cortex A75) cores @ 2.8 GHz, 4x Kryo Silver (Cortex A55) […]

Arm China appears to be fully independent of Arm

Arm China (安谋科技) has apparently split from Arm Holdings in an interesting saga. Last year we noted Allwinner R329 processor featured Arm China AIPU with 256 MOPS. But this AI accelerator was nowhere to be found on the official Arm website, which seemed odd. But it appears there have been conflicts with and within Arm China for a while. Allen Wu, who was President of ARM Greater China, Member of the Executive Committee between 2014 and 2018, and has been Chairman and CEO, Arm Technology (China) since April 2018, has set up an investment fund called Alphatecture Hong Kong Ltd in 2019 in order invest in Bestechnic, an ARM licensee and developer of audio chips, reaping hundreds of dollars in profit for himself. Arm Technology (China)’s board of directors was not impressed and voted 7 to 1 on June 4, 2020 to dismiss him, but Allen refused to leave since […]

MutantC V4 – DIY Raspberry Pi Handheld PC adds ESP32-S2 module

Earlier this year we wrote about Mutantc V3 DIY Raspberry PI UMPC after noticing a talk about it at FOSDEM 2021 online conference. MutantC V4 is a new version of the Raspberry Pi handheld PC that is both easier to build and cheaper. The new model replaces the Arduino Pro Micro board with a more compact ESP32-S2 module and offers a Lite version with even fewer parts (notification LED, IR blaster, IMU, etc..) to make it easier to build. The new MutantC v4 shares many of the same features of the previous versions: Supported SBCs – Raspberry Pi Zero, 2, 3, 4 and compatible. Wireless module for keyboard and other controls – Ai. Thinker ESP-12K module based on ESP32-S2 single-core WiFi microcontroller @ 240 MHz with 8MB flash Display – 2.8-inch, 3.5-inch, or 4-inch “GPIO” LCD such as AdaFruit PiTFT 480×320 display Keyboard – 56-key customizable keyboard with 2x shoulder […]

Linux 5.14 Release – Main changes, Arm, MIPS, and RISC-V architectures

Linus Torvalds has just announced Linux 5.14 release which happens to almost coincide with the anniversary of the initial announcement of the “small” project on August 25, 1991, about 30 years ago. Here’s Linux 5.14’s announcement: So I realize you must all still be busy with all the galas and fancy balls and all the other 30th anniversary events, but at some point you must be getting tired of the constant glitz, the fireworks, and the champagne. That ball gown or tailcoat isn’t the most comfortable thing, either. The celebrations will go on for a few more weeks yet, but you all may just need a breather from them. And when that happens, I have just the thing for you – a new kernel release to test and enjoy. Because 5.14 is out there, just waiting for you to kick the tires and remind yourself what all the festivities are […]

Leverage ESP32-S3 AI capabilities with the ESP-DL library

ESP32-S3 is the first Espressif wireless processor with AI instructions, and ESP-DL library for ESP-IDF allows you to easily leverage those AI instructions using boards such as the ESP32-S3-DevKitC-1. The ESP-DL library provides APIs for Neural Network (NN) Inference, Image Processing, Math Operations, and Deep Learning Models that make full use of ESP32-S3’s AI instructions with a 16-bit face recognition model running 6.25 faster, while the 8-bit model is 2.5 times faster than without acceleration. The ESP-DL library can be used as a project component. For instance, it can be used as a submodule of ESP-WHO computer vision framework, by simply copying it to the esp-who/components/ directory. The Model Zoo contains several pre-trained models for (human) face detection & recognition, and cat face detection, with more being developed including color detection and hand-pose detection. Espressif Systems also provides tools to use your own models, and a convention tool allowing you […]
