Snapdragon X50 5G Modem Makes it First Data Connection

5G technology is expected to launch in 2019, and Qualcomm has recently made a step towards this goal with the company announcing their first 5G data connection with Snapdragon X50 modem on on 28GHz mmWave Spectrum. The demonstration took place in Qualcomm Technologies’ laboratories in San Diego, and achieved Gigabit download speeds using several 100 MHz 5G carriers. Snapdragon X50 5G Modem’s product page lists some of the key features of the chip: Up to 5 gigabits per second download speeds Initial support for operation in the 28 GHz millimeter wave band. It can connect using up to 800 MHz of bandwidth via 8×100 MHz carrier aggregation. Supports advanced multiple input, multiple output (MIMO) techniques such as adaptive beamforming and beam tracking Composed of the modem as well as the SDR051 mmWave transceiver The modem can be paired with a Snapdragon processor to provide multi-mode 4G/5G capability, and the company […]

Xiaomi Mi A1 Review – Part 1: Unboxing, First Boot, Firmware Update, and Benchmarks

Xiaomi Mi A1 hardware specifications are pretty much standard for a mid-range smartphone, except possibly for its dual rear camera, and what makes it stand apart is really Android One program that promises regular firmware update, including to the latest “pure” Android version, during a 2-year period from launch. In my case, the phone is also interesting because so far I had only used smartphones with Mediatek SoCs, and Mi A1 is equipped with a Qualcomm Snapdragon 625 processor. SD625 should be slower than the Mediatek Helio X20 deca-core processor I’ve been using in Vernee Apollo Lite, but I’m curious to find out if some apps have been better optimized for Qualcomm processors. I’ll soon find out as GearBest sent me a review sample.I’ll start with an unboxing and first boot post, before writing the second part of the review in a couple of weeks once I’ve finished testing the […]

Getting Started with MicroPython on ESP32 – Hello World, GPIO, and WiFi

I’ve been playing with several ESP32 boards over the months, and tried several firmware images. I started with a tutorial for Arduino Core on ESP32, a few month later I tested ESP32 JavaScript programming with Espruino on ESPino32 board, and recently Espressif Systems sent me ESP32 PICO core development board powered by their ESP32-PICO-D4 SiP, and while I took some pretty photos, I had not used it so far. So I decided to go with yet another firmware, and this time, I played with MicroPython on ESP32, and will report my experience with basic commands, controlling GPIOs, and WiFi in this getting started post. Flashing Micropython Firmware to ESP32 Board Source code is available on Github, as a fork of MicroPython repo as ESP32 support has not been upstreamed yet. We could built the firmware from source, but there’s also a pre-built binary which you can download on MicroPython website. […]

STEGO BOARD Enables Neat Prototypes with Development Boards and Accessories (Crowdfunding)

If you’ve ever created a quick prototype for your own use, or for your company, you may have based it on a development board, and added some extra modules or add-on modules, as well as potentially accessories such as hard drives or power supply. Software is complete and it works, but it may look like a mess, and transporting it may cause cables to disconnect or other problems. STEGO BOARD should help in this case. It’s some kind of mounting systems compatible with the most common boards like Raspberry Pi 3, Rock64, or ASUS Tinkerboard, mini-ITX motherboards, mini PCs with VESA mounts, 2.5″ and 3.5″ drives, and so on. So you can create prototypes like the ones below. Six different products are available: STEGO BOARD 102 – 2 layers of the smaller board with 106 parts (stands, screws, zip ties). Can be used with mini PC, development board, up to […]
