JeVois-A33 is a Small Quad Core Linux Camera Designed for Computer Vision Applications (Crowdfunding)

JeVois Neuromorphic Embedded Vision Toolkit – developed at iLab at the University of Southern California – is an open source software framework to capture and process images through a machine vision algorithm, primarily designed to run on embedded camera hardware, but also supporting Linux board such as the Raspberry Pi. A compact Allwinner A33 has now been design to run the software and use on robotics and other projects requiring a lightweight and/or battery powered camera with computer vision capabilities. JeVois-A33 camera: SoC – Allwinner A33  quad core ARM Cortex A7 processor @ 1.35GHz with  VFPv4 and NEON, and a dual core Mali-400 GPU supporting OpenGL-ES 2.0. System Memory – 256MB DDR3 SDRAM Storage – micro SD slot for firmware and data 1.3MP camera capable of video capture at SXGA (1280 x 1024) up to 15 fps (frames/second) VGA (640 x 480) up to 30 fps CIF (352 x 288) […]

Android Things OS for the Internet of Things Supports Raspberry Pi 3, Intel Edison, and NXP Pico Boards

Google introduced Project Brillo a little over a year ago, an operating system based on Android, but with a smaller footprint optimized for Internet of Things applications. Brillo has now just become Android Things OS, with Google releasing a developer preview of Android Things working on Raspberry Pi 3, Intel Edison, and NXP Pico boards. The company has also updated the Weave platform to simplify connection of all types of devices to the cloud, and interaction with services like the Google Assistant. The Weave Device SDK currently supports schemas for light bulbs, smart plugs, switches, and thermostats, with more type of device supported in the future, as well as a mobile app API for both Android and iOS. Using an Android based OS instead of a pure Linux OS should make it easier for Android app developers to create smart devices thanks to the use of familiar Android APIs and […]

Firefly-RK3399 Rockchip RK3399 Development Board Launched on Kickstarter for $139 and Up

Firefly-RK3399 is the first, and for now the only one, development board equipped with the latest Rockchip RK3399 hexa-core Cortex A72 & A53 processor. It’s just not available yet, but the board has now been launched on Kickstarter where it is offered for $139 to $199 depending on options. Firefly-RK3399 board specifications: SoC – Rockchip RK3399 hexa-core big.LITTLE processor with dual core ARM Cortex A72 up to 2.0 GHz and quad core Cortex A53 processor with ARM Mali-T860 MP4 GPU with OpenGL 1.1 to 3.1 support, OpenVG1.1, OpenCL and DX 11 support System Memory Standard – 2 GB DDR3 Plus devkit – 4 GB DDR3 Storage Standard – 16 GB eMMC flash, micro SD card, M.2 socket Plus devkit – 32 GB eMMC flash, micro SD card, M.2 socket Video Output & Display Interfaces 1x HDMI 2.0 up to 4K @ 60 Hz 1x DisplayPort (DP) 1.2 interface up to […]

Getting Started with Pine64 PADI IoT Stamp – Part 2: Serial Console, GCC SDK, Flashing & Debugging Code

PADI IoT Stamp module powered by Realtek RTL8710AF ARM Cortex M3 WiFi SoC is a potential competitor to Espressif ESP8266 modules.  Pine64, the manufacturer of the module, sent me their kit with a $2 IoT stamp, a breakout board, a USB to TTL debug board and a J-Link debug board. In the first part of the review I’ve shown the hardware and how to assemble PADI IoT stamp kit. In the second part I’m going to write a tutorial / getting start guide showing how to control the board with AT commands, build the firmware with GCC SDK, and finally demonstrate how to flash and debug the firmware with the J-Link debugger. The Quick Start Guide indicates you need to connect the USB to TTL debug board to UART2 instead of UART1 as I did on the very similar B&T RTL-00 RTL8710AF module, and set connection settings to 38400 8N1.

Allwinner H2 Linux & Android SDK, and Allwinner XR819 WiFi Driver Released

Orange Pi Zero is an interesting little ARM Linux board thanks to its low price, but also because it features a new Allwinner H2 / H2+ quad core Cortex A7 processor very similar to Allwinner H3 minus the 4K video decoding part, as well as Allwinner XR819 WiFi module, which I have not seen on any other boards so far. But hardware without software is pretty much useless, so developers will be happy to find out that Allwinner H2 SDK with Linux (lichee) and Android has been released or leaked, and it also includes the Allwinner XR819 WiFi driver. You’ll find the SDK on Zoobab server with three main directory / files: Android folder – Android 4.4.2 SDK lichee folder – Linux 3.4.39 source code. However you’d probably better use Linux 3.4.113 currently released by sunxi-linux, or Linux mainline. The latter does have some limitations, and may or may not […]
