Samsung eMMC and UFS 2.0 embedded Flash Chips and Performance in 2016

Samsung does not always keep up its website up-to-date when it comes to its embedded flash chips, and performance metrics such as sequential read/write and random read/write values are not shown for all devices. The former is mostly important for data storage, while the latter may make a big difference for the operating systems responsiveness, and applications that rely on many short write and/or read operations. A table with the latest Samsung eMMC 5.0/5.1 and UFS 2.0 chips, and performance metrics somehow dropped in my computer. The company offers low end eMMC 5.0/5.1 flash with capacities between 4 and 16 GB with performance up to 285/40 R/W MB/s and 8K/10K R/W IOPS, mainstream chips between 32 and 128 GB delivery up to 310/140 MB/s and 14K IOPS, and all UFS 2.0 device are faster than any of the eMMC flash (limited in theory to 400 MB/s) with capacity between 16GB […]

Giveaway Week – VR SKY CX-V3 Android Virtual Reality Headset

It’s been a while since I’ve organized a Giveaway week, and with Christmas less than two months away, it might be a good time to launch another one. It will take place on October 31 – November 6 with one device or board offered every day, starting with VR SKY CX-V3 All-in-one Android VR Headset. CX-V3 review showed that it’s good enough to play 2D and 3D videos, but Allwinner H8vr might not be quite powerful enough for VR games, and the IPD (Interpupillary distance) is not adjustable, so depending on the distance between your eyes, virtual reality apps may not be usable at all. That’s not a problem for videos however. I’ll send the kit with all accessories to the lucky winner. To enter the draw simply leave a comment below. Other rules are as follows: Only one entry per contest. I will filter out entries with the same […]

Getting Started with RabbitMax Flex IoT and Automation Hat for Raspberry Pi

At the beginning of the month I showed how to assemble RabbitMax Flex, a Raspberry Pi HAT compliant add-on board for Raspberry Pi boards with 40-pin header, that targets IoT and home automation project with its relay, IR transmitter and receiver, I2C headers for sensors, buzzer, RGB LED, and more.  Since I’ve already described the hardware, I’ve spend some time this week-end following the user’s guide to play around with the board using a Raspberry Pi 2 board, and try various features. The user’s manual explains that you need the latest version of Raspbian, but I’d not played with my Raspberry Pi 2 board for a while, so the kernel and firmware were quite old:

So the first thing I had to do was to upgrade Raspbian. There are basically two options to upgrade, either downloading and dumping the latest Raspbian firmware image to your micro SD card, and […]

ESP32 Updates – ESP32-S Module Replaces ESP3212, ESP32 DevBoards for Sale, Arduino & NodeMCU Support

There have been some developments with regards to Espressif ESP32 in the last month since my post about upcoming ESP32 development boards. First ESP3212 module is no more, and has been replaced with ESP32-S module with about the same features, but it’s not pin-to-pin compatible, so the new module won’t work with older breakout boards made for ESP3212. ESP32-S is now out of stock on Seeed Studio, but you’ll find it on IC Station, Banggood, and others shops. One good news is that it’s now easier to buy – or at least pre-order – ESP32 development boards, although stock may still be an issue, as the platform is very popular. If you live in the US, you can now backorder “Sparkfun ESP32 Thing” for $19.95. ESP32 board can be powered by either a micro USB power supply or a LiPo battery, and exposes close to 30 I/O pins. ESP32 developer […]
