Qualcomm Snapdragon 845 Octa Core Kryo 385 SoC to Power Premium Smartphones, XR Headsets, Windows Laptops

Qualcomm Snapdragon 845 processor was expected since May 2017 with four custom Cortex A75 cores, four Cortex A53 cores, Adreno 630 GPU, and X20 LTE modem. with the launch planned for Q1 2018. At least, that what the leaks said. Qualcomm has now formally launched Snapdragon 845 Mobile Platform and rumors were mostly right, as the the octa-core processor comes with four Kryo 385 Gold cores (custom Cortex A75), four Kryo 385 Silver cores (custom Cortex A55) leveraging DynamIQ technology, an Adreno 630 “Visual Processing System”, and Snapdragon X20 modem supporting LTE Cat18/13. The processor is said to use more advanced artificial intelligence (AI) allowing what the company calls “extended reality (XR)” applications, and will soon be found in flagship smartphones, XR headsets, mobile PCs, and more. Qualcomm Snapdragon 845 (SDM845) specifications: Processor 4x Kryo 385 Gold performance cores @ up to 2.80 GHz (custom ARM Cortex A75 cores) 4x […]

Mediatek MT2621 Supports Dual Mode NB-IoT and GSM/GPRS for IoT, Wearables, and Industry 4.0

Mediatek introduced MT2625 ARM Cortex-M SoC supporting NB-IoT (aka LTE Cat NB1/NB2) compatible with 3GPP Release 14 last summer, and designed for global cellular IoT devices. The company has now unveiled a new NB-IoT part with Mediatek MT2621 ARM7 dual-mode IoT SoC that is capable of both NB-IoT R14 and GSM/GPRS connectivity for applications such as smart trackers, wearables, IoT security, smart metering and industrial applications. The chip would allow you to start deploying devices with GSM connectivity, and once available in your locale, switch to the more efficient NB-IoT protocol. Mediatek MT2621 specifications: Processor – Single ARM7 core @ up to 260MHz Memory – 160KB + 4MB PSRAM Internal Flash Connectivity Integrated Baseband, RF, Antenna, and Modem DSP NB-IoT ultra-low/low/mid bands defined by 3GPP Rel-14 GSM/GPRS Bluetooth 4.2 Display – LCM interface Camera – Camera interface Audio – Audio Amplifier Integrated PMU Mediatek is really light on details, but […]

HackaBLE Board is a Tiny, Breadboard-Friendly Bluetooth LE Development Board

Earlier this year, I wrote about Electronut Labs’ Bluey development board powered by Nordic Semi nRF52832 development board with BLE, NFC, and a few sensors, and partially open source hardware with the KiCAD schematics and PCB layout available on Github. The company is now back with another open source hardware nRF52832 BLE board, namely hackaBLE, that’s much smaller (28x18mm), and with 2.54mm pitch castellated pin headers making suitable for use for breadboard, or as a module on a custom designed board. hackaBLE board specifications: SoC – Nordic Semi nRF52832 ANT + BLE ARM Cortex-M4 @ 64 MHz processor with 512kB flash, 64kB RAM Connectivity – Bluetooth 4.2/5 LE and other proprietary 2.4 GHz wireless standards via chip antenna Expansion 2x 9-pin castellated headers with GPIO, 5V, 3.3V, and GND 2x 5-pin solder pads for more I/Os Debugging – 4-pin SWD header Misc – RGB LED, and user button Power Supply […]

Zidoo H6 Pro (Allwinner H6) TV Box Review – Part 2: Android 7.0 Firmware

Zidoo H6 Pro is the very first Allwinner H6 based 4K TV box. The Android 7.0 device support H.265, H.264 and VP6 4K video decoding, comes with fast interfaces such as USB 3.0, and network connectivity with Gigabit Ethernet and 802.11ac WiFi. I’ve already checkout the hardware in the first part of the review entitled “Zidoo H6 Pro (Allwinner H6) TV Box Review – Part 1: Unboxing & Teardown“, and since then, I’ve had time to play with the TV box, and report my experience with Android 7.0 in this second part of the review. First Boot and OTA Firmware Update I’ve connected a USB keyboard and a USB dongle with RF dongles for an air mouse and gamepad on the two USB ports, a USB 3.0 hard drive to the single USB 3.0 ports, as well as HDMI and Ethernet cables before powering up the TV box. I also […]

RedRat-X IR, Bluetooth & RF4CE Box Can Control Multiple TVs and Set-top Boxes

IR blasters can be used to control multiple IR devices through infrared, or other interfaces, for example DVR can use such device to change the channel of a set-top box just before recording. RedRat-X is one of those devices for automating control of TVs, STBs and other infrared equipment, but it’s quite more versatile, as beside its built-in IR blaster, it adds 3 IR outputs were you can connect your own IR transmitters, as well as USB and Ethernet for remote controls. Furthermore, it can also take add-on modules to emulate Bluetooth and RF4CE remote controls. RedRat-X specifications: IR blaster via the front of the unit. 0 mA to 250 mA in 100 steps. 3x plug-in IR jack sockets which can be used in two modes: Current mode (default): For use with plug-in IR flashers – 0mA to 100mA in 100 steps. Voltage mode: To interface to IR distributions systems, […]

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. ] […]
