Qualcomm Mesh Networking DevKit Supports Amazon AVS

Qualcomm Mesh Networking Devkit for Amazon AVS

The Qualcomm Mesh Networking Development Kit for Amazon AVS enables integration of Amazon Alexa Voice Services into mesh Wi-Fi systems. A somewhat recent blog post on Amazon Developer website explains the devkit is the first ever Amazon-qualified reference design for a mesh WiFi system with Alexa built-in. The reference platform is based on the Qualcomm IPQ4019 SoC, includes a rectangular 4-microphone array, far-field audio processing algorithms for noise suppression, acoustic echo cancellation, wake word engine, and the AVS Device SDK. Qualcomm Mesh Networking DevKit specifications: WiSoC – Qualcomm IPQ4019 quad core Arm Cortex-A7 processor @ 717 MHz with SIMD DSP, WiFi 5; 40 nm process technology System Memory – 1GB DDR3L RAM Storage – eMMC flash and microSD card Display I/F – LCD interface Connectivity WiFi Standards: 802.11ac Wave 2, 802.11ac, 802.11p, 802.11n Bands: 2.4 GHz, 5 GHz Peak speed: 1.733 Gbps Channel Utilization: 20/40/80 MHz, 5/10/20/40 MHz MIMO Configuration: 2×2 (2-stream) Wi-Fi Features: MU-MIMO, TxBF, Wi-Fi SON Bluetooth 5.0 …

Intel Launches WiFi 6 AX200 M.2 Wireless Card

Intel AX200 WiFi 6 M.2 Card

WiFi 6 (aka 802.11ax) can deliver up to 10 Gbps in theory, and provides better handling of high density scenario in train stations, conferences, etc… We’ve seen it implemented in some routers and smartphones, but most laptops don’t support the new WiFi standard, so in order to solve this little issue, Intel has now launched AX200 M.2 WiFi 6 card in the M.2 2230 and M.2 1216 form-factors. Intel AX200 works in the 2.4GHz band up to 574 Mbps, and in the 5.0 GHz band up to 2.4 Gbps. The “Cyclone Peak” card works with both USB and PCIe signals, support 2×2 MU-MIMO, and also supports Bluetooth 5.0. Drivers are/will be available for Windows 10 64-bit, Google Chrome OS, and Linux via the “IWLWIFI” driver. Pricing for the cards is said to be $10 and $17, but I could not find it listed anywhere just yet. A few more details may be found in Intel Ark. Via Phoronix and TechGenYZ …

ESP-WROOM-5C is a Side-Mounted ESP8285 WiFi Module

ESP-WROOM-5C

You’d think by now we’d have enough ESP8266 or ESP8285 WiFi modules, but based on an FCC listing, we now know that Espressif Systems has been working on another ESP8285 WiFi module – ESP-WROOM-5C – designed to be side-mounted. ESP-WROOM-5C specifications: SoC – Espressif Systems ESP8285 Wi-Fi 802.11 b/g/n WiFi 4 @ 2412 MHz ~2462 MHz; Station/SoftAP/SoftAP + Station modes WPA/WPA2 security with EP/TKIP/AES encryption PCB antenna Peripheral interface I2C/IR Remote Control GPIO/PWM Operating voltage – 2.7V ~ 3.6V Operating current – Average: 80 mA Minimum current delivered by power supply – 500 mA Dimensions – 19 x 16 x 3.2 mm Temperature Range – -40°C ~ 105°C Reliability Tests – HTOL/HTSL/uHAST/TCT/ESD The module supports firmware upgrade over UART or OTA (Over-The-Air). Software development can be done with the IDF SDK for custom firmware, but “Cloud Server development” is also possible, and an Android/iOS app can be provided for user configuration. There isn’t any other public information about ESP-WROOM-5C module …

MT3620 Mini Dev Board is a Cheaper Microsoft Azure Sphere Board

MT3620 Mini Dev Board

Announced nearly one year ago, Microsoft Azure Sphere is an ecosystem comprised of Azure MCUs with Microsoft Pluton Security System, Linux based Azure Sphere OS, and a secure cloud service called Azure Sphere Security Service. The first official Azure development board – MT3620 Development Board for Azure Sphere – was launched last year for $84.95. The kit may not have attracted a large number of developers, so there’s now a cheaper version – MT3620 Mini Dev board – going for $34.90 on Seeed Studio. Note that’s a pre-order and shipping is scheduled for May 13, 2019. MT3620 Mini dev board specifications: CPU Module – AI-Link WF-M620-RSA1 module with Mediatek MT3620AN single core Arm Cortex-A7 processor @ 500 MHz with 4MB SRAM, dual core Arm Cortex-M4F real-time core @ 200 MHz with 64KB RAM, Pluton security sub-system, and WiFi.

Xiaomi Mi A2 Review with Android 9.0 Pie

Mi A2 Review Android 9.0

I had been using Xiaomi Mi A1 Android One smartphone since the end of 2017,  and was mostly satisfied with it thanks to regular (monthly) firmware update, although I was a bit disappointed by the camera overtime. Eventually I had a serious issue with Mi A1’s eMMC flash, and stopped using it at the end of last year, or roughly after one year of service, since the phone became unusable, unbearably slow. Xiaomi Mi A2 and A2 Lite where released last summer, and having seen Mi A2 was getting an Android 9.0 firmware in Q4 2018, I asked GearBest whether they could send a sample to review the latest Xiaomi Android One phone. They accepted, and I posted the first part of the review in early December. However, at this time, I did not get the update, since it was not released in Thailand, but soon enough Xiaomi Mi A2 got upgraded to Android 9.0 Pie. I’ve now been using …

MXCHIP EMW3060 WiFi IoT module sells for less than $2

MXCHIP EMW3060

Over the last few years, we’ve seen several Arm based WiFi IoT modules trying to compete with Tensilica based ESP8266 including Pine64 PADI IoT Stamp and Air602 WiFi IoT modules with similar functionalities and price (around $2) as the Espressif modules. I have not seen many projects with any of those Arm based wireless modules, likely because Espressif Systems software ecosystem is mature, and it’s hard to compete for new entrants. Nevertheless there’s a new Arm WiFi IoT module, not based on Cortex-M core, but instead, MXCHIP EMW3060 is equipped with an older ARM9 core, 256KB RAM, and 2MB flash, and sells for just $1.79 on Seeed Studio in single quantity. The price further drops to $1.55 per unit if you order 50 pieces or more. MXCHIP EMW3060 WiFi IoT module specifications: SoC ARM9 core clocked at 120 MHz System Memory – 256KB SRAM Storage – 2MB flash Connectivity – 2.4GHz radio, 802.11 b/g/n WiFI, HT/40, support Station, Soft AP, …
