ReflowR is a $99 SMT Reflowing Tool for Makers and Students

You can solder SMT components to your custom board by hand, but it would be much faster if you could get a reflow tool instead to “bake” your board after placing the components. ReflowR SMT reflowing tool offers just that in a small and affordable form factor. Some people have tried to use DIY solutions to bake their board, but results may vary. ReflowR has been specifically designed to heat PCB offering constant results. It supports reflow, rework, MSD bake, or rework pre-bake, and follows JEDEC reflow profiles. You can also add a WiFi extension to monitor the tool from your smartphone and set the temperature profile. Two version are available: Smart ReflowR – Compact 600W system for for makers and learners. Large ReflowR – Larger 1200W system for professionals “STEM Inspiration kits” are also offered without a ReflowR kit, but with multiple components, solder paste, a few PCBs, tweezers, […]

YokaTV KB2 Review – Amlogic S912 TV Box with 32 GB Flash

CNXSoft: This is another review by Karl about Amlogic S912 based YokaTV KB2 TV box. Introduction Today we will be looking at Videostrong YokaTV KB2. Below are the specs from Videostrong website. This is my first S912 device so I had high expectation. I have been using it for quite some time now with no major issues. I received approximately 6 OTA updates since I started testing and some welcome updates have come. Build When I receive a box first thing I do is take it apart and check out the inside. I was excited when I found out it had 32 gig of storage. It is not too common. Then when I opened the box I was really happy to see an antenna that wasn’t soldered on. Makes it easy to add a different one. +1 for KB2. Then I noticed the heat sink. It seemed a little small. […]

Arduino MKRZero is a Smaller Arduino Zero Board

Arduino Zero was unveiled over two years ago with an Atmel SAMD21G18  ARM Cortex M0+ MCU in Arduino Uno Rev.3 form factor, the company has now launched Arduino MKRZero with the same MCU but using the much smaller Arduino MKR1000 form factor. Arduino MKRZero specifications: MCU – Atmel/Microchip SAMD21 32-bit ARM Cortex M0+ MCU @ 48 MHz with 32 KB SRAM, 256 KB flash (8KB for bootloader) External Storage – micro SD slot Digital I/O Pins – 22x GPIOs with 12x PWM, UART, SPI, and I2C, 8x external interrupts Analog Pins – 7x analog inputs (8/10/12-bit ADC), and 1x analog output (10-bit DAC) DC Current per I/O Pin – 7 mA USB – 1x micro USB port for power and programming Debugging – USB via Atmel’s Embedded Debugger (EDBG) on-board debugger, and JTAG Misc – reset button, 1x LED (pin 32), 32.768 kHz RTC Power 5V via micro USB port […]

Avantek H270-T70 384-core ARM Server Powered by Cavium ThunderX SoCs Can Be Bought Online

ARM servers have been around for a while, but usually it’s pretty hard to buy for individuals, and developer’s boards such as LeMaker Cello are never in stock, probably because the project has been canceled or suffered from further delays. However, if you have some uses for ARM servers and the cash that goes with it, Avantek Computer (UK) is selling some ARM based servers starting from an 1U Rack with a quad core Annapurna Alpine AL5140 processor up to Avantek H270-T70 with a 2U rack equipped with multiple Cavium ThunderX SoCs providing 384 ARMv8 cores to play with. Avantek H270-T70 server key features and specifications: SoCs – 8x Cavium ThunderX CN8890 processors with 48 custom ARMv8 cores each System Memory – 64x DDR4 ECC slots for up to 8TB memory Storage – 16x 2.5” hot-swappable HDD/SSD bays Connectivity – 8x 40GbE QSFP+ fiber ports (Cortina CS4343 controllers) Power Supply – […]

Android Things OS for the Internet of Things Supports Raspberry Pi 3, Intel Edison, and NXP Pico Boards

Google introduced Project Brillo a little over a year ago, an operating system based on Android, but with a smaller footprint optimized for Internet of Things applications. Brillo has now just become Android Things OS, with Google releasing a developer preview of Android Things working on Raspberry Pi 3, Intel Edison, and NXP Pico boards. The company has also updated the Weave platform to simplify connection of all types of devices to the cloud, and interaction with services like the Google Assistant. The Weave Device SDK currently supports schemas for light bulbs, smart plugs, switches, and thermostats, with more type of device supported in the future, as well as a mobile app API for both Android and iOS. Using an Android based OS instead of a pure Linux OS should make it easier for Android app developers to create smart devices thanks to the use of familiar Android APIs and […]

Banana Pi BPI-M64 & BPI-M2 Ultra Boards PDF Schematics Published

SinoVoip has recently released PDF schematics for both of their Banana Pi boards, namely BPI-M64 board powered by Allwinner A64 processor, and BPI-M2 Ultra board based on the latest Allwinner R40 SoC with an on-chip SATA interface. For most boards on the market, this should not be news, but SinoVoip does not always release schematics in a timely manner, so you may want to be noticed when it happens: BPI-M64 schematics – https://bananapi.gitbooks.io/bpi-m64/content/en/bpi-m64schematicdiagram.html BPI-M2 Ultra schematics – https://bananapi.gitbooks.io/bpi-m2-ultra-open-source-single-board-computer/content/bpi-m2ultraschematicdiagram.html The clear benefit of BPI-M2 Ultra is the presence of a SATA connector NOT implemented via a slow USB 2.0 to SATA bridge, but instead directly through the SATA interface of the R40 quad core processor. As for BPI-M64 ($46), it can be compared to Pine64+ with 2GB RAM and a WiFi module ($39), and despite the higher price it does come with some benefits like adb over OTG working, it is […]
