Khadas Edge RK3399/RK3399Pro Board Crowdfunding Campaign Launched

Khadas Edge is another upcoming Rockchip RK3399 board that we initially covered this summer, and comes with a particular design in the sense it is both a single board computer with USB and Ethernet port, and a system-on-module through its edge connector. Later on we found out, the company was working on a variant called Khadas Edge-V with the edge connector being replaced by a more standard 40-pin header, as well as Khadas Edge1S powered by Rockchip RK3399Pro for AI applications. The company has now launched the three boards and accessories through an Indiegogo crowdfunding campaign. I’ve already covered the two RK3399 boards in previous post, and the RK3399Pro based Khadas Edge-1S (2GB RAM, 2x MIPI-CSI, …) will be similar to Edge board but with , so instead I’ll have a closer look at the specifications for Khadas Captain carrier board for Khadas Edge / Edge-1S: Edge connector – 314-pin […]

Giveaway Week – Videostrong VS-RD-RK3399 Development Board

That’s the time of the year for another Giveway Week on CNX Software. They will be some development boards, add-on boards, and one gadget. You’ll have to keep reading this blog everyday to find out, but I’ll start with VideoStrong VS-RD-RK3399 development board and accessories. Also know as Mecool VS-RK3399, it is one of the many Rockchip RK3399 development board on the market. The board I have comes with 4GB LPDDR3, and 32GB eMMC flash, as well as all accessories above, minus the USB type-C cable which I can’t find anymore… A 12V/2A will also be provided in the kit given away. I reviewed the board with Debian, tested the SDK, and ran a few benchmarks in Linux about a year ago, and I found that while the board mostly worked as expected, software support and documentation needed some improvements. The SDK page is still there,but they have not really […]

Particle Mesh IoT Development Kit Review – Part 1: Unboxing

Back in February of this year, Particle introduced three low cost IoT development boards based on Nordic Semi nRF52840 wireless chip supporting “Particle Mesh” networking based on the 802.15.4 radio in the chip and OpenThread implementation of Thread IoT communication protocol. The company recently announced they were now shipping the kits pre-ordered earlier this year, and released two IoT development tools based on Node-RED and Visual Studio Code. Particle contacted me as well as to find out whether I was interested in reviewing their latest WiFi / Bluetooth / Mesh kit, and I’ve just received the bundle, which comes with a bunch of items, so I decided to write an unboxing post first to have a first look at the hardware, before playing with it in one or two weeks.

96Boards IoT Edition IVY5661 Board Features UniSoC UWP5661 WiFi 5 + Bluetooth 5 SoC

If you ever wanted to start a new IoT project with WiFi and Bluetooth connectivity, you’d like think about using Espressif ESP32 WiSoC that supports single band 802.11 b/g/n WiFi (WiFi 4) and Bluetooth 4.2 LE thanks to great community and software support on top of the ultra low cost of the solution. But in case your require 802.11ac (WiFI 5) – yes, I’m trying hard to get used to the new WiFi naming scheme for consumers -, or Bluetooth 5, Espressif Systems does not offer such solution yet. Instead you may consider UniSoC UWP5661 Arm Cortex-M4 WiSoC with WiFi 5 & Bluetooth 5 connectivity that will be found in the soon-to-be-launched UcRobotics IVY5661 96Boards IoT Edition board. I could not find lots of information about UWP5661 chip tself, so let’s jump directly to IVY5661 board specifications: SoC – UniSoC UWP5661 dual core Arm Cortex-M4 microcontroller @ 416 MHz manufactured […]

$94 MAKERphone DIY Mobile Phone Supports MicroPython, Arduino IDE, and Scratch (Crowdfunding)

If you ever wanted to buy a mobile phone that you can assemble yourself, RePhone Kit Ctreate going for $59 is a nice option, but in truth it does not exactly look like your typical phone with its almost square shape. It’s also good to have more option, that’s exactly what MAKERphone is offering with a DIY mobile phone targeting the educational market. Beside the educational value of the assembly also involving some soldering skills depending on the selected kit, kids will be able to learn to program the phone with MicroPython, the Arduino IDE (C language), and/or Scratch visual programming. MAKERphone kit content and specifications: MAKERphone circuit board with 8x user LEDs for backlight (and special effects), 4-way mechanical joystick, 12-button numeric keypad, A, B, C, D, E, and F buttons, DS3231 RTC chip, vibrator… Main microcomputer module based on Espressif Systems ESP32 WiSoC with 802.11 b/g/n WiFi, Bluetooth […]

$16 ESP32-A1S ESP32 Audio Development Kit Comes with 2 Microphones, Audio Jacks & Headers

Espressif ESP32 WiSoC can be integrated into various applications, and earlier this year Espressif Systems released ESP32 LyraTD MSC Audio Mic HDK (Hardware Development Kit) which I could test with Baidu DuerOS using Mandarin. Since then the company released the ESP-ADF Audio Development Framework that beside Baidu DuerOS, now supports Google Assistant and Amazon Alexa, so you don’t need to speak or learn Chinese to use the kit! 🙂 Another ESP32 audio board was the similarly named ESP32-LyraT, and now we have at least more more option with Seeed Studio selling ESP32-A1S WiFi + Bluetooth ESP32 audio development kit for $16.90 on their store. ESP32-A1S ESP32 audio development kit specifications: Wireless Module A.I. Thinker ESP32-A1S module based on ESP32 dual core Tensilica CPU clocked at up to 240MHz with 520 KB SRAM, and 8MB on-module PSRAM 802.11 b/g/n WiFi and Bluetooth 4.2 LE Storage – Micro SD card slot up […]

Linux 4.19 Release – Main Changes, Arm and MIPS Architectures

With Linus Torvalds taking a leave from the Linux kernel project, Greg Kroah-Hartman was the one to release Linux 4.19 last Sunday: Hi everyone! It’s been a long strange journey for this kernel release… While it was not the largest kernel release every by number of commits, it was larger than the last 3 releases, which is a non-trivial thing to do. After the original -rc1 bumps, things settled down on the code side and it looks like stuff came nicely together to make a solid kernel for everyone to use for a while. And given that this is going to be one of the “Long Term” kernels I end up maintaining for a few years, that’s good news for everyone. A small trickle of good bugfixes came in this week, showing that waiting an extra week was a wise choice. However odds are that linux-next is just bursting so […]

Tiny NanoPi Duo2 Board Comes with WiFi, a Camera Interface, an Optional 2G-IoT Dock

NanoPi Duo was launched last year as an ultra-cheap ($8+) Arm Linux board that fits into a breadboard. The board was powered by Allwinner H2+ processor coupled with 256 or 512MB RAM, and the infamous XR819 802.11b/g/n WiFi chip. FriendlyElec has now launched NanoPi Duo2, that’s still breadboard compatible, but with a slightly longer form factor, Allwinner H3 processor, 512 MB RAM, better WiFi thanks to an AP6212 module, and an extra camera interface. As we’ll see further below the company also developed a carrier board for 2G cellular IoT applications. NanoPi Duo2 specifications with highlights in bold showing differences again NanoPi Duo: SoC – Allwinner H3 quad core Cortex A7 processor @ 1.2 GHz with Mali-400MP2 GPU System Memory – 512 MB DDR3 SDRAM Storage – micro SD card slot, footprint for SPI flash Connectivity – 802.11 b/g/n WiFi + Bluetooth 4.0 LE (Ampak AP6212 module) with chip antenna, […]
