Z-Wave Open Standard to Enable Third-Party Z-Wave Silicon and Stack Suppliers

Roughly one year ago, Silicon Labs released a publicly available Z-Wave SDK and a Raspberry Pi 3 Image to make it easier to work with the wireless protocol targetting home automation. But Z-Wave specifications were still closed, which meant Z-Wave chips could only be purchased from Silicon Labs, a bit like LoRa chip can only be purchased from Semtech. The advantage of being closed is that you’re the only supplier, but this will limit market adoption, and customers may be wary of relying on a single partner for their long term plans. That must be why The Z-Wave Alliance and Silicon Labs have now decided to open Z-Wave specifications to Silicon and Stack suppliers. That paves the way to third-party software platforms and Z-Wave radios from some of the 700+ companies which are members of the Z-Wave Alliance. The Z-Wave specification release is scheduled for H2 2020, and will include […]

BOKRA NXP LPC824 and Nordic nRF52832 powered MCU Modules Follow MikroBUS Form Factor

We first wrote about MikroElectronika MikroBUS socket in 2015 while covering an SBC which featured one MikroBUS socket supporting one of the 150 Click boards available at the time. There are now over 700 Click boards to choose from, with the tiny modules offering motor drivers, buttons, short-range connectivity,  UART and other interfaces, as well as various sensors. But BOKRA had another idea: developing MCU based systems-on-module following MikroBUS form factor. BOKRA LPC824 Lite module The first of those modules is BOKRA LPC824 Lite with the following specifications: MCU – NXP LPC824M201JHI33 Arm Cortex-M0+ microcontroller @ 30 MHz with 32KB Flash Memory, 8 KB RAM I/O MikroBUS headers with SPI, I2C, UART, PWM, GPIOs 10-pin “Serial” header 4-pin I2C Grove connector for Seeed Studio I2C Grove modules Debugging interface – SWD Misc – Reset button, power LED, 2x user LEDs Power Supply – 5V/500mA via MIC5528 regulator Dimensions – 28.6 […]

Onion Omega2 Dash Enables Touch-based UI’s, Features Omega2S WiFi Module (Crowdfunding)

Onion, the team behind the Omega2 series self-styled computing modules has launched the Omega2 Dash a self-contained Omega2S module with a touchscreen. Unlike some modules integrating with a display that mostly comes in the form of a HAT (in the case of Raspberry Pi), USB, HDMI, or some unique data lines. The Omega2 Dash is a stand-alone 3.2″ TFT touchscreen display running a Linux OS, comes with a Micro USB, and boots in less than a minute, thanks to the Omega2S module attached to the back of the display screen. The Omega2S is the latest in the series of computing modules from Onion after succeeding the Omega2+.  Targeted to the IoT industry in its 24x20x2.8mm form factor, the Omega2S was designed for mass production and people interested in integrating IoT solutions into their products. Integrating a display to the Omega2S will be tricky. It will require investing in a custom […]

HackEEG Arduino Shield Reads Signals from Your Brain (EEG), Muscles (EMG), and Heart (EKG)

Biosignals are signals from living beings that can be continually measured & monitored, and some common methods to measure those biosignals include electroencephalogram (EEG) to monitor the electrical activity in your brain, electromyography (EMG) for recording the electrical activity produced by skeletal muscles, and electrocardiogram (EKG or ECG) to measure electrical activity of your heartbeat. Those can be used for brain interfaces which according to a recent Ericsson’s report may become commonplace by 2030 with users just thinking about commands, prosthetic arms, health and disease monitoring, and so on. Starcat has designed the HackEEG shield to experiment with all those three methods using an Arduino board and electrodes. HackEEG features and specifications: TI ADS1299 8-Channel, 24-Bit ADC for biopotential measurements SPI EEPROM for storing configuration data 8x analog-digital conversion (ADC) channels, each with a 24x programmable-gain amplifier (PGA). Up to 4x shields can be stacked on one Arduino Due for […]

RISC-V based PolarFire SoC FPGA and Devkit Coming in Q3 2020

Microsemi unveiled PolarFire FPGA + RISC-V SoC about one year ago, but at the time, development was done on a $3,000 platform with SiFive U54 powered HiFive Unleashed board combined with an FPGA add-on board from Microsemi. I’ve now been informed that Microchip has announced its Linux-capable PolarFire FPGA+RISC-V SoC would start shipping in Q3 2020 at the RISC-V summit and that a development kit will be sold for a few hundred dollars. PolarFire SoC FPGA   PolarFire SoC FPGA key features and specifications: Mid-Range FPGA optimized for Low Power High-speed serial connectivity with built-in multi-gigabit/multi-protocol transceivers from 250 Mbps to 12.7 Gbps Up to 461k logic elements consisting of a 4-input Look-Up Table (LUT) with a fracture-able D-type flip-flop Up to 31.6 Mb of RAM Power optimized transceivers Up to 1420 18 × 18 multiply-accumulate blocks with hardened pre-adders Integrated dual PCIe for up to ×4 Gen 2 Endpoint […]

Testing NVIDIA Jetson Nano Developer Kit with and without Fan

A few weeks ago I received NVIDIA Jetson Nano for review together with 52Pi ICE Tower cooling fan which Seeed Studio included in the package, and yesterday I wrote a getting started guide showing how to setup the board, and play with inference samples leveraging the board’s AI capabilities. I’ll now test the board with the stock heatsink in both 5W and 10W modes, and see if thermal throttling does occur, and then I’ll fit the tower cooling fan to find out if we can extract more performance that way and how much lower the CPU temperature is. Jetson Nano Stress Tests with Stock Heatsink Let’s install SBC-Bench testing utility,

check it’s properly installed,

and run it in 5W mode:

The temperature never went over 44.5°C, and no throttling occurred. tegrastats during 7-zip multi-core test:

Only two Cortex-A57 cores are used even under load, and power […]

AI inference using Images, RTSP Video Stream on NVIDIA Jetson Nano Devkit

Last month I received NVIDIA Jetson Nano developer kit together with 52Pi ICE Tower Cooling Fan, and the main goal was to compare the performance of the board with the stock heatsink or 52Pi heatsink + fan combo. But the stock heatsink does a very good job of cooling the board, and typical CPU stress tests do not make the processor throttle at all. So I had to stress the GPU as well, as it takes some efforts to set it up all, so I’ll report my experience configuring the board, and running AI test programs including running objects detection on an RTSP video stream. Setting up NVIDIA Jetson Nano Board Preparing the board is very much like you’d do with other SBC’s such as the Raspberry Pi, and NVIDIA has a nicely put getting started guide, so I won’t go into too many details here. To summarize: Download the […]
