Zidoo H6 Pro (Allwinner H6) TV Box Review – Part 1: Unboxing & Teardown

Allwinner H6 is a quad core Cortex A53 processor designed for 4K HDR set-top boxes and TV boxes that also comes with high speed interfaces like USB 3.0 and PCIe. While at least one other company is working on an Allwinner H6 development board, Zidoo is the only company that I can find whose made a TV box based on the processor: Zidoo H6 Pro. They’ve just send me a sample from their local supplier for review, and as usual, I’ll start by checking out the hardware inside out, before testing the firmware and multimedia capabilities in the second part of the review in a few weeks. Zidoo H6 Pro Unboxing The company has slightly changed the design of their retail package. It also shows some icons with the main features like 4K, 3D, H.265, 2GB DDR4, Android 7.0 with ZIUI, etc… The box ships with a HDMI cable, a […]

U-Blox announces NINA-B3 Bluetooth 5 Wireless MCU Modules

Bluetooth 5 promises to quadrupling the range and double the bandwidth of Bluetooth LE connection. However, we’ve seen not all Bluetooth 5 solutions will provide all features in a comparison between Nordic Semi nRF52840 vs nRF52832 vs nRF52810 Bluetooth 5 ready SoCs, as while all three platforms will handle the higher bandwidth just fine, only the nRF52840 will extend the range up to 4 times. That’s why you want want to make sure you get recent hardware capable of fully handling Bluetooth 5, and U-blox has just announced NINA-B3 Bluetooth 5 module series, based on nRF52840 SoC, that will both provide longer range and higher bandwidth. U-blox NINA-B3 module comes in two family flavors: NINA‑B31, comes pre‑flashed with u‑blox’s Connectivity Software, eliminating the need for embedded programming. Support for AT command set, and u-Blox low energy serial port service NINA‑B30 using nRF52840’s ARM Cortex-M4F as an “Open CPU” that allows […]

STMicro BlueNRG-MESH SDK for Bluetooth Mesh to Include Code for Firmware, Android and iOS Apps

Earlier this summer, the Bluetooth SIG announced Bluetooth Mesh, which supports many-to-many (m:m) device communications for up 32,767 unicast addresses per mesh network (in theory), and is compatible with Bluetooth 4.0 or greater hardware. Several companies immediately unveiled Bluetooth Mesh SDK at the time including Qualcomm, Nordic Semi, and Silicon Labs. ST Micro has now unveiled their own BlueNRG-MESH SDK which the company claims is “the market’s only three-part SDK that provides two app developer packages for Android and iOS, and the embedded-development software for building smart objects such as light fittings and sensors”. Sadly, details about the SDK are near inexistent now, except – as one would expect – BlueNRG-MESH SDK will work with ST BlueNRG Bluetooth low energy wireless network processor based on an ARM Cortex M0 core, and corresponding development kits. [Update: STSW-BNRG-Mesh page has many more details about the SDK including the architecture diagram below. ] […]

A First Look at ESP32 PICO Core Development Board Powered by ESP32-PICO-D4 SiP

Last week, I wrote about ESP32-PICO-D4 system-in-package (SiP) that contains ESP32 WiSoC, 4MP SPI flash, a crystal oscilloscator and some passive components in a single 7×7 mm package in order to allow smaller designs based on ESP32. The company noticed the post, and asked me whether I’d be interested in receiving “some development boards based on ESP32 PICO”, an offer hard to refuse :), and within a couple of days I received the package below. So I ended up with 10 identical development kits, the company probably thought it was no worth paying for DHL to only send one or two development boards… The boards may also be part of some contests… We’ll see 😉 So let’s take two, and have a closer look at “ESP32_PICO_Core_Board_V3″… It comes with two rows of 20 pins with access to all I/Os, and features three main chips: ESP32-PICO-D4 SiP, AMS1117 voltage regulator, and Silabs […]

Zidoo X7 Review – Part 2: Android 7.1 Firmware, ZDMC, WiFi, and More

Zidoo X7 is an Android TV box powered by Rockchip RK3328 processor similar to Bqeel MVR9 with 2GB RAM, but instead of provide Gigabit Ethernet, and 802.11 b/g/n WiFi, it comes with Fast Ethernet, and 802.11 b/g/n/ac WiFi, so is better suited to people using WiFi instead of Ethernet for media streaming. You’ll find plenty of photos in the first part of the review entitled “Zidoo X7 TV Box Review – Part 1: Unboxing & Teardown“, and I’ll report my experience with Android 7.1.2 firmware in this second part. First Boot, Setup, and First Impressions I connected two RF dongles for MINIX NEO A2 Lite air mouse and Tronsmart Mars G01 gamepad via a USB hub, a USB keyboard to take screenshot, and a Seagate USB 3.0 hard drive to the single USB 3.0 port on the box. I perform tests with Ethernet in most reviews, but with Zidoo X7, […]

The Embedded Linux Conference & IoT summit 2017 took place in the US earlier this year in February, but there will soon be a similar event with the Embedded Linux Conference *& Open Source Summit Europe 2017 to take up in Europe on October 23 – 25 in Prague, Czech Republic, and the Linux Foundation has just published the schedule. It’s always useful to find out what is being discussed during such events, even if you are not going to attend, so I went through the different sessions, and compose my own virtual schedule with some of the ones I find the most interesting. Monday, October 23 11:15 – 11:55 – An Introduction to SPI-NOR Subsystem – Vignesh Raghavendra, Texas Instruments India Modern day embedded systems have dedicated SPI controllers to support NOR flashes. They have many hardware level features to increase the ease and efficiency of accessing SPI NOR […]
