Bluetera II is a motion-enabled IoT development board that supports protocol buffers (Crowdfunding)

Tensor Iotera Group (TIG), an Israeli based technology company, has launched a powerful IoT development board featuring motion sensing called Bluetera II and supporting Google Protocol buffers. Bluetera II came from the idea that developing an IoT application shouldn’t be complicated. Hardware is hard, and scaling for manufacturing might also be more daunting than initially anticipated. So instead of going through those troubles, why don’t you go the route of something that works, and most importantly, is scalable, as TIG is advocating with their Bluetera IoT development platform. Bluetera II is the 2nd generation of this IoT platform. The Bluetera II board is equipped with a 9-axis motion sensor, Bluetooth 5 enabled Nordic nRF52840 SoC core, which features an Arm Cortex-M4 FPU, with 1MB of Flash, 256KB of RAM, and lastly, an SDK based on Google’s Protocol Buffer (protobuf) technology. The device can function as a BLE Central (Master) and […]

Krescue for Khadas VIM Boards Enables Backup/Restore of eMMC flash, Access to the Terminal, and More

Sometimes things go wrong, and you need a way to recover your system, either by restoring a backup or accessing your system to check it out and hopefully fix the issue. Krescue is a minimal firmware image (21MB compressed) for Khadas VIM boards designed to do just that, and more. Some of the highlights of Krescue firmware image include: Full eMMC flash dump/backup to Micro SD card, USB, or LAN host. Restore the compressed dump (.img.gz) into an eMMC on the same device or another device Rescue shell for expert users. Shell access via UART, USB network, and Web browser You’ll find Krescue for Khadas VIM1, VIM2, VIM3 and VIM3L on Khadas website which can be flashed to a MicroSD card using balenaEtcher. You can then insert the card into your board, and boot into maskROM mode to access the menu above, and control it with the IR remote control […]

SwitchTrick Switching Power Supply Board Helps you Test your Breadboard Circuit

We’ve covered several power supplies for breadboards over the years including toaster breadboard power supply with variable voltage output, or the portable, battery-powered MEGO power supply that allows you to power your project on the go. The SwitchTrick is another one of those breadboard power supplies but with testing in mind, as it takes input from various sources, and with jumper selection for voltage from 1.8V to 6V allows you to easily simulate different battery voltage levels, or the test the overvoltage protection of your circuit for example. SwitchTrick key features and specifications: Step-down converter – TI TPS62160 3-17V step down-convertor adjustable from 0.9-6V out at 1A. Power Input – 3V to 17V via 5.5×2.1mm power jack for 9V battery or wall supply Micro USB connector for 5V 2-pin JSY PH connector for battery 2x large plates holes for alligator clips Power Output (selectable by a jumper) 1.8V 2.5V 3.0V […]

Sony Spresense 6-core MCU Development Board Now Supports Java

Sony Spresense board was introduced in spring 2018 with a 6-core Cortex-M4 microcontroller from the company, GPS & GLONASS, as well as audio support. The breadboard-compatible board could also be inserted into an Arduino UNO R3 compatible base board, and Sony offered support for both the Arduino IDE and a C-based NuttX-based SDK. You’ll find some more details and photos in our “review”. Sony has now partnered with MicroEJ to provide developers with Java support on Spresense board through MicroEJ Virtual Execution Environment (VEE). A Java simulator (VEE Virtual Device) allows you to develop software for Spresense independently of the hardware. Beside plenty of libraries, MicroEJ VEE features MEJ32 32-bit virtual core is compatible with various architectures including ARM Cortex-M, ARM Cortex-Ax, RX, V85, MIPS32, TriCore, and Tensilica. Java enables application portability which means that any GUI/IoT/Security or application code can run on various embedded systems supported by MicroEJ VEE. […]

Sovol SV01 Upgrade with BigTreeTech SKR mini E3 Control Board

Karl here with a quick upgrade guide. The one complaint I had in the review of the SV01 3D printer was it was loud. Today we are going to look at resolving part of the problem by replacing the Creality board with the BigTreeTech SKR mini E3 V1.2 control board sold on Amazon for around $37. Fan noise at a later date. This board is ideal because the SD card, USB, and screws line up for nearly a perfect replacement. I did not bother hooking up the filament runout sensor. I have never found them particularly useful and always ensure I start with enough filament and bypassed it for the review. The board comes with TMC2209 drivers which significantly reduce the stepper motor noise as well as stop any salmon skin. SKR Mini E3 Warning This board is a replacement for the board found on the Ender 3. Below is […]
