NXP i.MX 7ULP Enters Mass-Production, EVK and Systems-on-Module Announced

Last year, we wrote about F&S Elektronik Systeme PicoCORE MX7 system-on-module (SoM) powered by NXP i.MX 7ULP processor manufactured with a 28nm FD-SOI process, and that was announced a year earlier. The official launch of the module was planned for Q3 2018, but there have been some delays as LinuxGizmos reports NXP has only started mass production of their i.MX7 ULP this June. With the official launch of i.MX 7ULP, the company also introduced the official i.MX 7ULP Evaluation Board (MCIMX7ULP-EVK) as showcased on Element14’s community and several other companies announced i.MX 7ULP systems-on-modules. Benefits of NXP i.MX 7ULP Processor The i.MX7 ULP family of processors is an extremely power-efficient series, that is utilizing lower power for more functions. The SoC is being touted as the most power-efficient processor that can be obtained that also houses a 3D GPU.  Although like the i.MX7, the i.MX 7ULP combines both Cortex-A7 and Cortex-M4 cores but can effectively bring the power states even …

Sony CXM1501GR ELTRES LPWAN Module Promises a Range of over 100 Km

While there are many LPWAN (Low Power Wide Area Network) standards, three appear to dominate the news namely LoRaWAN, SigFox, and 3GPP NB-IoT/eMTC. They all offer long range and up to 10-year of battery life enabled by the use of low bitrate which is fast enough to send sensor data. We can now add another LWPAN standard to the list, as Sony has developed ELTRES wireless communication standard suitable for IoT networks, and announced their CXM1501GR ELTRES module with a range of over 100km, even while traveling at 100km/h. Key features and specifications: ELTRES Connectivity Antenna radiated power – 20mW Communication direction – Uplink only Frequency – 923.6 MHz to 928.0 MHz (23-channel frequency hopping) Main modulation system – π/2 Shift BPSK Sub-modulation system – Linear chirp modulation Transmission system – Four repeated transmissions of 0.4 sec or shorter packets Reduction of interference with other systems – CSMA (Carrier Sense Multiple Access) Error correction code – LDPC (Low Density Parity …

Rockchip RK1808 AI Compute Stick Launched with Linux SDK

RK1808 AI compute stick

Rockchip RK1808 looks like a nifty and inexpensive little chip for artificial intelligence applications delivering up to 3.0 TOPS at low power, and the company has already released documentation and a Linux SDK with Caffe and Tensorflow framework support for the chip. So the main hurdle now is to get hardware to play with. Some people are selling (samples?) of the official RK1808-EVB on Taobao, but it costs close to $500 US.  There’s still no RK1808 development board, but Rockchip has discreetly launched the RK1808 AI Compute Stick a few weeks ago. RK1808 AI Compute Stick specifications: SoC – Rockchip RK1808 dual core Cortex-A35 processor with NPU AI inference performance – 3 TOPS for INT8, 300 GOPS for INT16, 100 GOPS for FP16 Video – 1080p60 H.264 decoding, 1080p30 H.264 encoding Camera, ISP – 2MP camera support, ISP with BT.601/656/1120 support Host Interface – USB 3.0 port Power Supply – Via USB port Dimensions – 60 x 19 mm It …

$100 Reolink Argus 2 is a Wire-Free IP Camera with Optional Solar Panel

Reolink Argus 2 Security IP Cam

This morning I had a look at battery-powered IP cameras since they avoid the hassle of wiring power and/or Ethernet around the house. I could remember I covered Immedia Blink IP camera with up to 2-year battery life back in 2014, and the company did very well since it got acquired by Amazon, and Blink IP security camera is now sold on Amazon US for $99.99 and up. It’s probably one of the best, if not the best options, for low-cost battery-powered cameras but the problem is that they only ship to a limited number of countries. Last year, there was a new entrant with Eufy Evercam outdoor IP camera with up to one year of battery life, but again it’s not easy to purchase from overseas, and the price starts at $279.99 for a single camera system. I also covered a solar and battery powered IP camera made by Wanscam a few years ago, and it could do the …
