May 23rd, 2017 2 comments

A couple of weeks ago I wrote about Rakwireless’ RAK CREATOR Pro development board based on Realtek Ameba RTL8711AM Wireless MCU, and part of their Wiskey family of development boards. Sub-family include WisNode for IoT boards, WisAP for OpenWrt boards, WisPLC for PLC hardware, and WisCam for WiFi video camera boards. The company has recently introduced Wiscam RAK5281 Arduino compatible Linux board powered by a Nuvoton ARM9 MCU, and supporting a camera module or an SD card + USB module. RAK WisCam specifications: SoC –  Nuvoton N32905R3DN ARM926EJ processor @ 200 MHz with 8KB internal SRAM, 16KB IBR internal booting ROM, 16Mbit  x16  DDR2 memory Storage – 128 MBit SPI flash, included sub-module adds micro SD card Connectivity – 802.11 b/g/n WiFi via Realtek RTL8189FTV module Camera via sub-module 648×488 pixel VGA CMOS Image Sensor (GC0308); 102° FOV Video –  QVGA (320×240) 30FPS, VGA(640×480) 30FPS, MJPEG encoding Photo – JPEG, 16 bits/pixel – RGB565, 32bits/pixel – ARGB8888 Audio – 16-bit…

8Power Vibration Energy Harvesting Technology Powers Batteryless LPWAN GPS Trackers, MEMS Sensors

May 23rd, 2017 No comments

While IoT products usually promises one to 10 years battery life, they will be several billions of them, and ARM’s CEO even forecast one trillion IoT devices in the next 20 years. Recharging batteries at home may be fine, but imagine having to recharge or replace batteries on top of electric poles, inside walls, in remote locations, and other hard to reach places, considerable resources would have to be deployed just to replace or recharge battery every year or whenever the battery is close to being depleted.  That’s why work on energy harvesting technology for batteryless devices may be so important, and 8Power is one of the companies working in the field through their vibration energy harvesting technology that is said to harvest up to 10x the power of competing devices under comparable condition thanks to the use of parametric resonance phenomenon. The company has recently announced their Track 100 family of LPWAN GPS tracker, such as Track 100XL relying on…

This $8 USB Transceiver Can Add 433 MHz Device Support to your Home Automation Gateway

May 23rd, 2017 2 comments

With the advent of WiFi and Bluetooth IoT, 433 MHz devices are becoming less popular but are still used for doorbells, motions sensors, windows/door sensors, etc… If you have such devices at home, one way to integrate those into your home automation system is to use an ESP8266 WiFi to 433 Mhz bridge between your gateway and 433 MHz capable products. However, you don’t even need the middleman if you use a USB 433 MHz transceiver connected directly to the gateway. Nathan Chantrell found such USB dongle on Banggood for about $8, and managed to make it work with his Debian Gateway using Node-RED. 433 MHz USB dongle and features: Connectivity 433 MHz transceiver Range – up to 30 to 100 meters (Line of Sight) Tx and Rx for PT2262, PT2260, PT2264, PT2240, EV1527, HS2303-PT codes Can transmit multiple signals independently Control interface – Serial over USB @ 9600 bps Power Supply – 5V via USB port Power Consumption –…

Qualcomm Snapdragon 845 Octa-core Processor To Feature ARM Cortex A75 Cores (Reports)

May 22nd, 2017 6 comments

According to reports from China, Qualcomm’s next application processor (or rather mobile platform) will be Snapdragon 845, and if accurate, the comparison table below between the Snapdragon processor and Hisilicon Kirin 970 SoC shows the former will be powered by some customized (魔改) version of yet-to-be announced ARM Cortex 75 cores. Snapdragon 845 octa-core processor will be manufactured using Samsung 10nm LPE processor, come with four custom Cortex A75 cores, four Cortex A53 cores, an Adreno 630 GPU, and an LTE X20 modem supporting LTE Cat 18 for up to 1.2 Gbps download speed. Other features like 802.11ad (High bandwidth, short range WiFi), UFS 2.1, and LPDDR4X were already found on earlier model. I’ve been unable to find further details about ARM Cortex A75 right now, and we have to wait until ARM Techcon 2017 before getting more details. Mobile phones powered by Snapdragon 845 are supposed to start shipping in Q1 2018. Via Wccftech According to reports from China,…

$399 Intel Euclid Robotics Devkit Runs Ubuntu & ROS on Intel Atom x7-Z8700 Processor

May 22nd, 2017 No comments

We’ve seen many mini PC based on Intel Atom x5/x7 “Cherry Trail” processor in the last year, but Intel has also integrated their low power processor into hardware aimed at robotics, such as Intel RealSense development kit based on Atom x5 UP Board and RealSense R200 depth camera. The company has now launched its one-in-all Intel Euclid development kit combining Atom X7-Z8700 processor with a RealSense camera in a single enclosure. Intel Euclid specifications: SoC – Intel Atom x7-Z8700 Cherry Trail quad core processor @ up to 2.4GHz with Intel HD Graphics Gen 8 System Memory – 4GB LPDDR3-1600 Storage – 32GB eMMC 5.0 flash, Micro SD slot up to 128GB Video Output – micro HDMI port up to 4K @ 30 Hz Audio – 2x I2S interfaces, 1W mono speaker, 3x DMIC with noise cancellation Camera – Intel RealSense ZR300 camera RGB camera – 2MP up to [email protected], 16:9 aspect ratio, rolling shutter, fixed focus, 75° x 41.5° x…

PragmatIC Manufactures Ultra Thin and Flexible Plastic Electronics Circuit, Plastic ARM Cortex M0 MCU Coming Soon

May 22nd, 2017 4 comments

Electronics manufacturing now relies on silicon wafers, and it works great for many applications. However, some other applications require or benefit from a cheaper price, thinner circuits, and flexibility, and PragmatIC addresses all those three issues with technology to print electronics circuits on plastic sheets. The technology is said to costs less than 1/10th cost of silicon, with the circuit printed on 10 μm thick flexible plastic “wagers” with support for 10 layers. Circuit starts from basic gates up to ARM Cortex M0/M0+ chip as shown above. Simpler circuits are currently sold for as low as $0.01, but the area for Cortex M0 MCU is 1cm2, and a bit too big for commercial applications, so they plan on shrinking the process to make it commercial viable. ARM is an investor in the company, and PragmatIC is ramping production capacity with the ability to manufacture on billion plastic chips/circuits in 2018. They have 6 types of products/solutions: PragmatIC Compute – Digital…

Arduino Cinque Combines SiFive RISC-V Freedom E310 MCU with ESP32 WiFi & Bluetooth SoC

May 22nd, 2017 5 comments

SiFive introduced the first Arduino compatible board based on RISC-V processor late last year with HiFive1 development board powered by Freedom E310 MCU, but  the company has been working with Arduino directly on Arduino Cinque board equipped with SiFive Freedom E310 processor, ESP32 for WiFi and Bluetooth, and an STM32 ARM MCU to handle programming. Few other technical details have been provided for the new board, but since it looks so similar to HiFive1, I’ve come with up with preliminary/tentative Arduino Cinque specifications: MCU – SiFive Freedom E310 (FE310) 32-bit RV32IMAC processor @ up to 320+ MHz (1.61 DMIPS/MHz) WiSoC – Espressif ESP32 for WiFi and Bluetooth 4.2 LE Storage – 32-Mbit SPI flash I/Os 19x Digital I/O Pins 19x external interrupt pins 1x external wakeup pin 9x PWM pins 1/3 SPI Controllers/HW CS Pins I/O Voltages –  3.3V or 5V supported USB – 1x micro USB port for power, programming and debugging Misc – 6-pin ICSP header, 2x buttons…
