Weightless Development Kits are Finally Available (Sort of)

The first version of the Weightless standard aiming at lowering cost of IoT communications was published in 2013, but so far development kits were nowhere to be found. Nwave has now launched a Weightless-N SDK using sub-GHz spectrum, but not the white space spectrum used by Weightless-W, probably due to regulatory hurdles. Specifications and features of Nwave development board: MCU – Silicon Labs EFM32G210F128 ARM Cortex M3 MCU @ 32 MHz with 128KB flash, 16KB SRAM Connectivity – RM3 radio module (868MHz) and antenna connector (X3) USB – X1 USB port for connection to PC or UART interface, X2 micro USB port Debugging – UART, and 10-pin JTAG connector (X4) Expansion header – 16 through holes for GND, 3.3V, GPIOs, ADC, Timers output, I2C, etc… (X5) Misc – Three Jumpers for UART and other selections (TBD), reset buttons for USB ports?

Zidoo X6 Pro Android TV Box Review

Zidoo X6 Pro is a 64-bit ARM Android TV Boxes  based on Rockchip RK3368 processor, promising support for HDMI 2.0 and video decoding up to 4K2K @ 60Hz. While the others I’ve tried so far, such as Beelink i68,  are pre-loaded with some version of Kodi 14.2, X6 Pro comes with a modified version of Kodi 15.1. I published pictures of the Zidoo X6 Pro TV box and board a few days ago, and today I’ll review the box’ features, performance, and capabilities. First Boot, Settings and First Impressions I’ve connected a USB hard drive to one of the two USB ports, as well as a USB hub with two RF dongles for Tronsmart Mars G01 gamepad and MeLE F10 Deluxe air mouse, a USB keyboard, and a USB webcam. I’ve also inserted an Ethernet cable, an HDMI cable, an optical audio cable, a Class 10 micro SD card, as […]

Xiaomi Mi Smart Remote Center Review

Xiaomi Mi Smart Remote Center is a tiny box with WiFi connectivity and IR transmitters that is used to control infrared enabled devices such as TVs, medai players, air conditioners and more with your Android smartphone. The good thing is that it only costs $20, so I asked GearBest to send a sample to check it out, which they did. I’ll start this review by checking out the hardware, before running MiHome app to control a television and air conditioner. Xiaomi Mi Smart Remote Center Unboxing and Teardown The package is just a cardboard box with Mi logo. Once you open the page there’s a sticker with the QR core redirecting to MiHome app. You can peel it off, and take the box out of the package, where you’ll also find a USB to micro USB cable for power, and a user’s manual in Chinese only. To open the device […]

AMS AS7000 Biosensor is Designed for Strapless Optical Heart Rate Monitors

Heart rate monitors (HRM) with chest straps are now being replaced by more comfortable strapless HRM, such as UWatch UX. These products are enabled by photoelectric sensors that sample light modulated by blood vessels, which expand and contract as blood pulses through them. One of such solutions is the recently introduced AMS AS7000 including a Cortex M0 core, and a DSP implementing algorithm to process raw photoplethysmography (PPG) readings from the sensors to convert them into digital HRM and HRV (Heart Rate Variability) values. Highlights of AS7000 Biosensor: MCU – ARM Cortex M0 with 4KB RAM, 32 KB EEPROM I/Os – 9 GPIOs, UART, SPI, I2C Analog electrical and optical Frontends Hardware sequencer Synchronous detector Integrated LEd driver with current control Optical filters Supply Voltage – 2.6 – 3.6V Temperature Range –30 to 70°C Package – 18 pins AS7000 can deliver greater accuracy when it is paired with an external […]

Zidoo X6 Pro Unboxing and Teardown

There are so many Rockchip RK3368 TV boxes on the market that it’s difficult for products to stand out. But Zidoo X6 Pro might be one of these products bringing a little more, as beside frequent firmware updates, Zidoo’s RK3368 TV box may be the first to officially run Kodi 15.x, while most others manufacturers have decided to stick with Kodi 14.2 in their latest firmware, and the company also released Kodi source code modifications for 7.1 audio pass-through, 3D MVC support, and hardware video decoding in compliance with Kodi’s GPL license. As usual, I’ll start by taking some pictures of the device and board, before writing a full review in the next few days. Zidoo X6 Pro Unboxing I got the following package via DHL, which somehow decided to take my picture as I received the parcel… The package includes some of the key features of the device include […]

ATT7039AU Micro-controller Features an Energy Meter Unit for Power Meters

About two years ago, I purchased Northwest T8 power meter, and it worked fine for about three months, but one day the top plastic broke as as unplugged it, rubber bands prolonged its life for a few more weeks, but eventually the display stopped working, and keep it in my drawer for long while, until today, when I decided to have a closer look at how it was done. The PCB is called CZ-7039-B2, and the top includes the display, 4 user buttons, as well as JTAG through holes (P2) and 2.54mm header (P1) with TDO, TMS, GND and 3.3V signals, as well as a pin called P1600, but I still haven’t found out what it might be for. I’ve also taken the board out completely, to find out everything is basically handled by a single 48-pin chip called ATT7039AU. After a Google search, I quickly found out the chip […]

Review of Voyo V2 Intel Atom Z3735F mini PC with Battery and SSD

Voyo V2 is another Intel Atom Z3735F mini PC pre-installed with Windows 10 Home, but it has some interesting features such as a 64GB SSD connected via a USB to SATA bridge on top of the regular 32GB eMMC, and a 5,000 mAh battery acting as a UPS. Since I have already received several of such platforms including MeLE PCG01, Wintel W8, and MeLE PCG03 and that there are usually few differences in regular benchmarks, I’ll focus on what varies between platforms: Windows activation status, storage and network performance, as well as power consumption. System Info and Windows Activation One of the shortcoming of this mini PC is that it only comes with a full sized USB port, and a micro USB port. So if you plan to use it as a PC with USB keyboard and mouse, you’ll need to use a USB hub, or at least a USB […]

Orange Pi PC Not Booting? You Are Not Alone…

Orange Pi PC development board launched at the end of August, and quickly went viral thanks to low $15 price tag. The company, Shenzhen Xunlong Software,  is fairly small, with just over 10 employees, so when they started getting several thousands customers in a short time, they may have been overwhelmed, and this likely resulted in delays with regards to shipping, and acceptance into Orange Pi forums. Several people have now received their boards, and while many found it to work fine, I’ve been informed several people apparently got a non booting device. People on Youtube and Orange Pi Forums also complained about a booting issue until Ethernet lights up, or Ethernet not working, while other reports Linux is working, but not Android. Unless there was a bad batch during manufacturing, it’s hopefully mostly a firmware issue. The person who reports Ethernet not working, first used the images from Orange […]
