Over the last few years, I’ve written several article about LoRaWAN, Cellular IoT, and Sigfox based long range low power IoT solutions. DASH7 is another LPWAN (Low Power Wide Area Network) standard that operates on the same 868 and 915 MHz ISM bands as LoRa and Sigfox, but has much lower power consumption, and the cost of a shorter range up to 500 meters, instead of the 5+km associated with LoRa or SigFox. The DASH7 Alliance Protocol (D7A) is an Open Standard, and if you want more details you can download version 1.1 of the specifications on DASH7 Alliance website. I’m writing about DASH7 today thanks to an article on ST blog about Wizzilab’s Wizzikit, an evaluation kit and framework for DASH7 with a gateway, and several nodes that can also optionally support LoRaWAN and Sigfox protocols. The kit is comprised of the following items: WizziGate GW2120 Ethernet/Wifi/Dash7 gateway – based […]
USBCEE Tiny-PAT Board Helps Testing USB-C Power Adapters (Crowdfunding)
USB power delivery allows for up to 100W charging using 20V @ 5A through a USB type C port, and the specifications also mandate supports for various voltages between 5V and 20V. However, some USB-C power adapter that not be fully compliant with the specifications, potentially risking to damage your device. USBCEE Tiny-PAT board has been created in order to test such power adapters to make sure they are compliant with USB PD 2.0/3.0 specifications. Tiny-PAT board features and specifications: Supported USB Spec Version – PD 2.0 / PD 3.0 Max Voltage: 24 V Max Current: 5 A Max Power: 100 W USB type C receptacle Misc – Fail and Pass LEDS, S4 mode button, through holes for VBUS & GND Power Consumption: ~10 mA (may vary based on voltage) Dimensions – 35 x 20 mm By default, the board will test all power rules advertised by the power adapter, […]
IkaScope WiFi Oscilloscope Probe Works with Windows, Linux, Mac OS X, Android and iOS
Last year, I wrote about Aeroscope, a portable Bluetooth oscilloscope that looks somewhat like a Stabilo Boss highlighter pen, and sends measurements over the air directly to your Android and iOS tablet or smartphone. It was introduced through a crowdfunding campaign which eventually failed, but Aeroscope can now be purchased for $199 on Amazon US or their own website. If you’d prefer WiFi over Bluetooth, and would like something that also works on Windows, Linux, and/or Mac OS X, IKALOGIC has just launched IkaScope WiFi oscilloscope probe compatible with all popular mobile and desktop operating systems. IkaScope WS200 specifications: Analog Bandwidth – 30 MHz @ -3dB Sample Rate – 200 MSps Connectivity – 802.11 b/g/n/e/i WiFi @ 2.4 GHz configurable as access point or station Input Range – +/-40 V range CAT1 Offset Range – +/- 20V to +/- 40V offset Input Impedance – 10MΩ || 14pF Input Contact – […]
SanStar WS-3A Medical Board Runs Android 5.1 on Rockchip RK3288 SoC
Warp United, a “Chinese Health 2.0″/point-of-Care medical technology company based in Shenzhen, launched Warp 3 medical recorder – an Android powered handheld device supporting various vital signs and ultrasound medical modules – earlier this year, and the company has now just introduced SanStar WS-3A motherboard powered by Rockchip RK3288 quad core Cortex-A17 SoC, and running Android 5.1 in order to allow engineers to develop and connect their own medical modules via the various interfaces of the board, and create their own medical products. SanStar WS-3A medical motherboard specifications: SoC – Rockchip RK3288 quad core Cortex-A17 processor @ 1.8GHz with an ARM Mali-T764 GPU with support for OpenGL ES 1.1/2.0 /3.0, OpenVG1.1, OpenCL, Directx11 System Memory – 2GB or 4GB DDR3 Storage – 8GB, 16GB, or 32GB eMMC flash, micro SD slot up to 32GB Video Output / Display I/F HDMI 2.0 up to 3840 x 2160 pixel embedded DisplayPort (eDP) […]
Review of Sonoff RF Bridge, Sonoff 4ch Pro, and Sonoff POW with Sonoff-Tasmota Firmware
Karl here. Today we are going to look at 2 new and one older Sonoff devices. Sonoff RF Bridge – $9.90 433MHz RF to WiFi Bridge Sonoff 4ch Pro – 4 Gang WiFi RF Smart Switch Sonoff POW – Wireless switch with power metering capabilities I spent very little time with the stock firmware on the device. I don’t like the fact that an Internet connection is needed, and I am not in control. As of the time of this writing I found the Ewelink was not configurable enough to meet my needs. There is one feature that is really nice that I could easily see keeping stock firmware. It is the Alexa Skill. It worked. I am also currently reviewing Vobot Smart Alarm Clock with Alexa integration and had no trouble controlling the Sonoff devices with Alexa. But unfortunately I am lazy and want everything automatic so I can’t […]
Getting Started with Espruino & JavaScript on ESP32 with ESPino32 Board
Venus Supply Co., Ltd, better known as ThaiEasyElec, is a company based in Thailand, selling embedded systems and development board, as well as providing development services based in Thailand. The company sent me their latest board called ESPino32 powered by Espressif ESP-WROOM-32 WiFi and Bluetooth module for evaluation. While the board is supported in Arduino-esp32, I’ve already tested Arduino with ESP32-Bit module & ESP32-T board, so after checking out the hardware, I’ll load it with something different: Espruino, a firmware allowing for JavaScript programming over the serial console, or a Web based IDE. ESPino32 Unboxing and Soldering The board shipped with four female headers, and I/O stickers. The board includes ESP-WROOM-32, exposes I/Os through four 10-pin headers, features CP2104 chip for serial to USB debugging via micro USB port, two buttons (reset and program), a user LED connected to IO16, and a jumper to select between regulated power supply (micro […]
