ASM2362 USB 3.1 Gen2 to PCIe Chip is Designed for USB NVMe SSD Drives

ASM2362

Most USB enclosure or expansion drive are designed with a SATA interface that tops out at 6 Gbp. That’s fine in most cases,  but if your host computer comes with USB 3.1 Gen2 SuperSpeed 10 Gbps (SuperSpeed+) port capable of even better performance, ASMedia now has a solution for faster USB drives with their ASM2362 USB 3.1 Gen2 to PCIe NVMe SSD chip. The solution is pretty new, and ASMedia has not setup a product page on their website yet, but they showcased a demo at Computex 2018.  In the photo above a Samsung 960 Pro SSD M.2 is connected to  another USB board  ASMedia – likely based on AS3142 Gen2 xHCI Host Controller – itself connected to a computer with a USB 3.1 Gen2 port.  The photo below shows CrystalDiskMark benchmark results comparing ASM2362 USB to NVMe solution to a standard USB to SATA enclosure. While the USB to SATA SSD achieves around 550 MB/s, the USB 3.1 to …

UM25C is a Better USB Power Meter with built-in Display, Bluetooth, and Android & Windows Apps

UM25C

Products such as USB Charger Doctor are good way to test your USB chargers or cables, as well as checking the power consumption of USB powered development boards. You just plug them into a USB port, and connect the load, and you’ll see the real-time voltage and current shown on an LED display. Those do the job, but I’ve just been made aware of UM25C USB meter tester that improves a lot on the concept with a dot matrix display capable of showing charts, and Bluetooth connectivity to send the data to Android or Windows devices. UM25C specifications: Display 1.44″ color LCD display 0-5 brightness setting Auto screen off time – 0 to 9 minutes Refresh rate – 2Hz Measurement Range & Accuracy Voltage – 4-24.000V ±0.5‰ + 2digits Current –  0-5.0000A ±1‰ + 4 digits Capacity – 0-99999mAh Energy accumulation – 0-99999mWh Load impedance – 0.8Ω-9999.9Ω Time range – 0-99h59min59s Temperature range – -10℃ to 100℃ ±3℃ Connectivity – …

YC-CDA19Q is an 8-Port Quick Charge 3.0 Capable USB Charger with a Display Showing Power Consumption

USB charger doctor is a cheap and easy way to monitor the voltage and current from a USB 2.0 port or charger, but you may have more than one device to monitor, and USB 3.0  type C ports as well as fast charger are now quite common, so it may not be suitable for all situations. Bakeey YC-CDA19Q USB charger hub could be an interesting power monitoring device with 7 USB ports, including one supporting Quick Charge 3.0 fast charging, and an extra USB type C port.

Scrcpy Open Source Software Let You Control an Android Phone via a Windows, Mac OS, or Linux PC

Have you ever wished you could control or mirror your Android smartphone using your computer? Scrcpy, a free and open source program by Genymotion may fit your needs, and works on Windows, Mac OS or Linux. You just need to install (or build) a program on your host computer, connect your phone via USB, switch to developer mode, enable USB debugging, and run the program which will automatically install the server (a jar file) on your phone, which does not need to be rooted. The easiest way to try is with Windows since the developers already provide pre-built binaries, but I installed it on Ubuntu 16.04 instead since it is the operating system I use daily. Some of the packages in Ubuntu 16.04 are a bit old so it took me a couple of hours to successfully install it, and I’d recommend going with Ubuntu 17.10 or 18.04 daily build if you can. First let’s create a working directory, and …
