Huawei Unveils Balong 5G01 5G Cellular Modem Chip, and 5G Routers

5G will start to take off in 2019. so we should be expecting hardware announcement this year, after having seen solutions by Qualcomm and Ericsson previously, Huawei has unveiled their Balong 5G01 5G Arm SoC and 5G CPEs (Customer Premise Equipment) / routers at Mobile World Congress 2018. We don’t have a whole information about the chip, except it’s a 64-bit Arm based SoC compatible with 3GPP telecommunication standard for 5G working with both sub-6 GHz and mmWave bands, and capable of achieving 2.3 Gbps peak throughput. Huawei Balong 5G01 chip is found in two HUAWEI 5G CPE, basically 5G WiFi router, one working at sub 6 GHz (low frequency) comprise of one indoor deice, and the other working at mmWave bands (high frequency) that requires two devices one indoor, one outdoor to receive the signal, since the latter would have troubles going through walls. The CPEs come with high […]

Samsung Galaxy S9 and S9+ Smartphones Launched with Snapdragon 845 or Exynos 9810 SoC

After various leaks on the web, Samsung has now officially launched their flagship smartphones – Samsung Galaxy S9/S9+ – at Mobile World Congress 2018. The phones look very much like last year’s Samsung S8/S8+ smartphones, but include faster processors with either Qualcomm Snapdragon 845 or Samsung Exynos 9810, better cameras (e.g. super slow motion mode @ 960 fps, low light improvements), some design tweaks (fingerprint scanner under the camera instead of on the side), and some new software features, like AR Emoji that creates your own virtual avatar based on your photo. Samsung Galaxy S9/S9+ specifications: SoC Qualcomm Snapdragon 845 octa-core processor with four Kryo 385 cores @ up to 2.8 GHz, four Kryo 385 cores @ up to 1.7 GHz, Adreno 630 GPU; 10nm Samsung Exynos 9810 oct-acore processor with four Exynos M3 core @ up to 2.7 GHz (Anandtech claims the max frequency can only be achieved when […]

SODAQ SARA is an Arduino Compatible Cellular IoT Board with LTE-M, NB-IoT, and GNSS (Crowdfunding)

There really seems to be a push for cellular IoT those days, with new hardware coming up every week.  Following up on their NB-IoT shield for Arduino last year, SODAQ has now launched two versions of SARA boards based on u-blox SARA LTE-IoT modules, and u-blox M8Q GPS/GNSS module. Both boards are Arduino compatible thanks to a Microchip SAMD21 MCU, and while u-blox SARA board follows the Arduino form factor, u-box SARA SFF is much more compact (50×25.4 mm) and potentially easier to integrate into a project or product. Another pretty unique feature (AFAICT) is that you can power the board directly with a solar panel. u-blox SARA board specifications: Wireless module (three options) with external antenna: SARA-N211 NB-IoT, band 8 and 20, for the European and African market SARA-R410M Dual mode LTE-M and NB-IoT module for all global bands SARA-R412M Triple mode module with LTE-M, NB-IoT and 2G for […]

Synthetic Sensors Combine Multiple Sensors and Machine Learning for General-Purpose Sensing

Sensors can be used to get specific data for example temperature & humidity or light intensity, or you can combine an array of sensors and leverage sensor fusion to combines data from the sensors to improve accuracy of measurement or detect more complex situation. Gierad Laput, Ph.D. student at Carnegie Mellon University, went a little further with what he (and the others he worked with) call Synthetic Sensors. Their USB powered hardware board includes several sensors, whose data can then be used after training through machine learning algorithms to detect specific events in a room, car, workshop, etc… List of sensors in the above board (at frequency at which data is gathered): PANASONIC GridEye AMG8833 IR thermal camera  (10 Hz) TCS34725 color to digital converter (10 Hz) MAG3110F magnetometer (10 Hz) BME280 temperature & humidity sensor, barometer (10 Hz) MPU6500 accelerometer (4 kHz) RSSI data out of 2.4 GHz WiFi […]

3D Rendering and Video Composite Output on ESP32 Boards

A few years ago, we already saw it was possible to transmit color signals over NTSC using an ESP8266 board with the signal received on a TV with an analog tuner. CNLohr had to connect an antenna to the I2S pin of his ESP8266 module, and disable WiFi. But surely we should be able to do the same with ESP32, and potentially even better thanks to the two cores. That’s exactly what Bitluni successfully managed by connecting his LoLin32 board to the composite input of his TV with one handling the TV signal output (in grayscale) and the other core rendering 3D objects in real-time. But any ESP32 board could be use instead. The hardware connection is very easy. We just need two wires, one connected to the GND pin and outer part of the RCA connector, and the other connected to GPIO 25 (DAC1) and the inner part of […]

A First Look at ESP32-LyraTD-MSC Audio Mic HDK with Baidu DuerOS Assistant

Earlier this year, Espressif Systems had unveiled their ESP32-LyraTD-MSC Audio MiC HDK (Hardware Development Kit) which features an ESP32-WROOM module, a 4-mic array DSP, 3 microphones, an audio jack, and various I/Os. I received the board a couple of weeks ago, and while there’s no public information released yet, the company provided me with ESP32-LyraTD-MSC User Guide in English. Eventually, I’d expect Google Assistant and Amazon Alexa to be supported, but in the meantime I had to leverage my (lowly) Chinese language skills to get started since the kit is pre-loaded with firmware connecting to Baidu DuerOS voice assistant. ESP32-LyraTD-MSC Unboxing The kit came in a bland Espressif Systems carton box. Inside the package, I could only find one kit comprised of two boards. The bottom board read ESP32_MicrosemiDSP_Mainboard-V1, and does not show much apart from marking for connectors, headers and the power switch. While the top comes with eight […]

CYCPLUS A2 is a 3-in-1 Device Combining Power Bank, Air Pump and Flash Light

Sometimes I come across some products that do not seem to make any sense. I had that exact feeling when I first discovered CYCPLUS A2, an air pump with a battery, and a flash light to top it out. But as I read more about it, this 3-in-1 gadget may indeed be useful to cyclist, since it offers a convenient way to inflate tires, provides backup power for your smartphone, as well as a backup light in case the one on your bike gets broken for instance. CYCPLUS A2 specifications: Display to set pressure and check status Buttons to adjust settings and turn on/off light Maximum Pressure – 150 PSI / 10.3 BAR / 990 KPA / 10.5 kgf/cm2 Inflation Time – Car: 8 minutes; road bike: 2.5 minutes; mountain bike: 2 minutes; basketball: 30 seconds Light – 80 lumen USB – 1x micro USB port for charging, USB type […]

Wibeee Power Monitoring Device Plugs right into Your Home’s Circuit Breaker Box

We’ve covered several smart plugs or switches capable of monitoring electricity consumption and displaying results right in a smarphone app, or computer’s web browser with products such as Sonoff S31 or Broadlink SP2 WiFi smart sockets, or Sonoff POW switch. Those work for individual plugs, but if you want to cover your full house, you’d need several of those, and in some case it may not be so convenient as no plugs may be available for example for lights or air conditioner. Smilics Technologies has come up with an easier method, although less granular, thanks to their WIBEEE device that clips to your fuse / circuit breaker box using DINZERO “clip-on” technology, and available in single and  three phase models. Main features: Voltage Range – 85 to 265 V AC @ 50 ~ 60 Hz with 2% accuracy + variation in range of use depending on temperature, humidity, etc… Current […]
