Compulab Fitlet2 Fanless Apollo Lake Mini PC is Designed for Industrial IoT Gateways

Compulab Fitlet mini PCs were introduced in January 2015 with AMD Mullins processors, namely AMD A4 Micro-6400T or E1 Micro-6200T both of which including Radeon graphics, and supporting up to 8GB RAM, mSATA, up to two HDMI port, up to four Gigabit Ethernet ports. The company has now launched Fitlet2 mini PCs, replacing AMD processors by Intel Apollo Lake SoCs, supporting up to 16 GB RAM, and designed for “demanding IoT applications” with support for wide temperature range, and long term support and warranty. Fitlet2 specifications: SoC (from a choice among three) Intel Atom x7-E3950 quad core processor @ 1.6 / 2.0 GHz with 18 EU HD graphics; 12W TDP Intel Atom x5-E3930 dual core processor @ 1.3 / 1.8 GHz with 12 EU HD graphics; 6.5W TDP Intel Celeron J3455 quad core processor @ 1.5 / 2.2 GHz with 12 EU HD graphics; 10W TDP System Memory – 1x […]

EasyVolts USB Dongle Outputs 0-24V DC, Exposes UART, GPIO/PWM, RS-485 Signals

A while ago, I wrote about USBminiPower, a USB power supply with 3.3V, 5V, and one variable DC output up to 14.3V adjustable with a rocker switch, and equipped for a 4-digit LED display showing current intensity and voltage. But recently, I was made aware of another USB power supply – EasyVolts USB dongle – that supports 0 to 24V DC, and also exposes either UART pins, or RS-485 signal, plus two GPIO/PWM pins. EasyVolts specifications: USB – 1x USB port for power, communication Power Supply function: Input voltage: 5V from USB port Output voltage: 0-24V Max output current: 1A Max output power: ~2.4W (e.g. 24V/0.1A; 3.3V/0.55A) Voltage resolution: <50mV Current resolution: <2mA I/O expansion 4- pin to be used as UART (Tx/Rx) or RS-485 + 2x GPIO/PWM UART – speed: 300-230400 bit/sec; resistance of Tx/Rx pins: 300 Ohm PWM – Base frequency: 240kHz.; frequency division configuration: 1-65535; duty cycle […]

Giveaway Week – Khadas Vim Pro Development Board

For the final day of this giveaway week, I’ll send Khadas Vim Pro development board to a new home. The board is powered by an Amlogic S905X processor coupled with 2GB RAM and 16GB storage, features 10/100M Ethernet and 802.11ac WiFi, and support 4K video playback and output via its HDMI 2.0a port. The board supports various operating systems such as Android, LibreELEC, dual boot Android/Ubuntu, etc.. and I wrote a Ubuntu review / getting started guide for the board in February. At the time, the image was still “raw” with many steps to perform by the users, and part of the documentation needing to be worked on. But the company (Szwesion) and members of the community are usually active in resolving user issues on the forums. I’ll give away the kit I’ve received with the board in an acrylic case, a USB to USB type C cable for power, […]

Giveaway Week – Nextion Enhanced 7″ Capacitive Display

My Nextion Enhanced NX8048K070 display will soon find a new home. The 7″ display comes with a capacitive touchscreen, an enclosure, and can work in standalone mode thanks to a built-in processor and a 8-pin FPC connector for I/Os, or connected to a micro-controller through a UART interface. I did a mini review of the display, mostly showing a teardown, and how to use Nextion Display Editor Windows-only tool to design your own user interface. The GPIOs are not really convenient to use with the required flat cable, and the company did not send me their $5 IO board, which would have made things easier. Learning curve may be a little sharper than needed as I’ve not found the Windows software to be very user-friendly, and documentation could be improved too. I’ll give the display with enclosure, micro USB power board, and UART cable as shown on the first photo. […]

Lab in a Box Concept Embeds x86 Server and 6 ARM Boards into a PC Case for Automated Software Testing

The Linux kernel now has about 20 millions line of code, Arm has hundreds of licensees making thousands of processors and micro-controllers, which end up in maybe hundreds of thousands of different designs, many of which are not using Linux, but for those that do, Linux must be tested to make sure it works. The same stands true for any large software used on multiple hardware platforms. Manual testing is one way to do it, but it’s time consuming and expensive, so there are software and hardware continuous integration solutions to automate testing such as Linaro LAVA (Linaro Automated Validation Architecture), KernelCI automated Linux kernel testing, and Automotive Grade Linux CIAT that automatically test incoming patch series. Both CIAT and KernelCI focus on Linux, and rely on LAVA, with KernelCI leveraging hardware contributed by the community, and proven to be effective as since it’s been implemented, failed build configs dropped […]

Giveaway Week – Wio GPS Tracker Board

It’s Friday, and the fifth day of giveaway week on CNX Software. Today, I’ll be giving away Wio Tracker, an Arduino compatible board based on Microchip / Atmel SAMD21 ARM Cortex M0 MCU with GPS, Bluetooth, 2G GSM/GPRS connectivity. My review of the board was rather negative, as I only managed to make Bluetooth 3.0 work while following the documentation as it was back in May. Since then the documentation seems to have improved, and other people have been more successful than me, and made the blink LED, and GPS samples to work. This version of the board only support 2G, so make sure it is still supported in your region/country. 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 IP and/or email address. Contests are open for 48 hours starting at […]

WifiMETRIX Wi-Fi Networks Analyzer Supports Packet Injection, Throughput Analysis

Panasonic Showcases Flexible Batteries with Wireless Charging System

Flexible batteries such as PowerStream lithium polymer batteries can be integrated into new application such as smartcards, and could help wearables have longer battery life by adding batteries into clothes, wristbands or chestbands for example. You’d still need to charge them however, and in some cases adding a USB port (micro USB or type C) may negate the benefit of having a thin flexible battery, but Panasonic has a solution as the company added wireless charging capability to their flexible batteries. The solutions showcased at Ceatec Japan 2017 on October 3-6, 2017 were flexible lithium-ion rechargeable batteries with 0.45mm thickness, and 18, 42 and 65mAh capacity. Battery voltage is 3.8V, charging voltage 4.35V, and the batteries can be bend up to a radius of 25 mm, and twisted by up 25°. Such batteries are meant to be attached to human body and clothes for medical and health management applications, or […]
