Xiaomi Unveils Their Very Own ESP32 Development Board, Module & SDK

We now have plenty of modules and board based on Espressif System ESP32 dual core wireless SoC, and a fairly good software support with ESP IDF SDK, Arduino Core,  MicroPython, Espruino and other solutions. So I was surprised when I saw Teo Swee Ann, Espressif CEO, posted photos about an event – Xiaomi IoT Developer Conference – where Xiaomi apparently introduced their own ESP32 development board, together their own SDK (still empty right now) compatible with the company’s Mijia ecosystem, as part of their “Open IoT platform” The slide below translates as “WIFI module –  Automated manufacturing / 4-fold foolproof mechanism / whole process tracing / cost price (about 15 RMB)” and “Open source SDK”, with the price likely the price of Xiaomi ESP32 module (ESP-WROOM-32C) shown on board above (Thank to hm for translation). I could not find much information at this early stage, except new partnership between Baidu […]

Review of ITEAD Studio IP66 Waterproof Case for Sonoff Wireless Switches (and Other Boards)

ITEAD Studio recently launched a waterproof enclosure for $2.90 (now at still a decent $3.90), rated IP66, for their family of Sonoff wireless switches, so you can safely use them outdoors protected from rain and dust. The company sent me one sample together with Sonoff RF switch supporting WiFi and 433MHz RF connectivity so that I can test the case, and write a review describing my experience. I’ll focus on the waterproof since this is the main focus of this review, and beside Sonoff RF, you can also use Sonoff basic, various other Sonoff boards (POW, TH10/T16), and even other development boards as we’ll seen below. I’ll be using the stock firmware with eWelink app, but if you prefer alternative firmware like ESPurna or Sonoff-Tasmota, you may want to flash it to your Sonoff now. The waterproog case has two parts, a rubber cord, two waterproof PG7 connectors, and four […]

Nexell NXC100 Voice Recognition Chip, NXP4330Q Processor, and ALTO Development Board

I wrote about NanoPi Fire2 & Fire3A boards based on Nexell S5P processors a few days ago, and at the time, as I checked out Nexell website, I found out about the company’s NXC100 Voice Recognition SoC that can be used in 4-mic array board. The chip can then be connected through SPI to a host processor, and Nexell appears to have a NXP4330Q Smart Voice kit based on their quad Cortex A9 processor of the same name. But since documentation is really limited, I looked for more details, and came across NXP4330Q based ALTO board design by InSignal, which sold the Exynos powered Arndale boards a few years back. Nexell NXC100 Voice Recognition SoC The chip is the only product from the “A.I related” section of therir website, but more are likely to come out as the company is working on GP-GPU (General Purpose GPU), machine learning, and even registered […]

Lab in a Box Concept Embeds x86 Server and 6 ARM Boards into a PC Case for Automated Software Testing

The Linux kernel now has about 20 millions line of code, Arm has hundreds of licensees making thousands of processors and micro-controllers, which end up in maybe hundreds of thousands of different designs, many of which are not using Linux, but for those that do, Linux must be tested to make sure it works. The same stands true for any large software used on multiple hardware platforms. Manual testing is one way to do it, but it’s time consuming and expensive, so there are software and hardware continuous integration solutions to automate testing such as Linaro LAVA (Linaro Automated Validation Architecture), KernelCI automated Linux kernel testing, and Automotive Grade Linux CIAT that automatically test incoming patch series. Both CIAT and KernelCI focus on Linux, and rely on LAVA, with KernelCI leveraging hardware contributed by the community, and proven to be effective as since it’s been implemented, failed build configs dropped […]

Intel Speech Enabling Developer Kit Works with Alexa Voice Service, Raspberry Pi 3 Board

We’ve known Intel has been working on Quark S1000 “Sue Creek” processor for voice recognition for several months. S1000 SoC is based on two Tensilica LX6 with HiFi3 DSP, some speech recognition accelerators, and up to 8x microphones interfaces which allows it to perform speech recognition locally. The solution can also be hooked to an application processor via SPI, I2S and USB (optional) when cloud based voice recognition is needed. Intel has recently introduced their Speech Enabling Developer Kit working with Amazon Alexa Voice Service (AVS) featuring a “dual DSP with inference engine” – which must be Quark S1000 – and an 8-mic array. The kit also includes a 40-pin cable to connect to the Raspberry Pi 3 board. Intel only provided basic specifications for the kit: Intel’s dual DSP with inference engine Intel 8-mic circular array High-performance algorithms for acoustic echo cancellation, noise reduction, beamforming and custom wake word […]

Sonoff Wireless Switch Family Gets a $3 IP66 Waterproof Enclosure

ESP8266 powered ITEAD Studio Sonoff wireless switches have been popular because they are inexpensive, highly customizable thanks to work from the community leading to open source projects such as ESPurna and Sonoff-Tasmota, and come fully packaged so you don’t need to make your own case for it. That works well for indoor projects, but if you needed to control outdoors lights, gate, water pump, etc… you had to protect the device from humidity/rain. That may not be necessary anymore as the company is now selling Sonoff Basic with an IP66 waterproof enclosure for $7.75, or the case only for $2.90.Sonoff waterproof case: Ingress Protection Rating – IP66 Material – PC V0 Dimensions – 132.2 x 68.7 x 50.1mm (See details) Weight – 145.0g IP66 rating is not suitable for prolonged immersion, but it should be good to protect against rain or high humidity. The box ships with two standardized PG7 […]

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, […]
