Arduino Compatible ASME TIGER Board Supports Thread on NXP Kinetis KW41Z WiSoC

The new Arrow ASME Tiger board is the latest addition to the ASME line up, with an eye towards IoT hardware prototyping. The board carries two MCUs for different types of development depending on the operators need. The board is Thread and WiFi ready, and the Tiger is also Arduino compatible. The MCU’s are as follows: The ATSAMD21J18A-64 Ultra-low-power microcontroller using the 32-bit ARM Cortex-M0+ processor. The WiSoC is the KW41Z which is an ultra-low-power, highly integrated single-chip device that enables Bluetooth® low energy (BLE) v4.2 and IEEE® 802.15.4 RF connectivity for portable, extremely low-power embedded systems. The working unit is for very low power applications. The integrated balun reduces system cost and board area, and the sensors are plentiful and easy to access. You’ll find a user guide (PDF), as well a bootloader and sample code on Github. Specifications for the SMART SAMD21 Memory 256KB in-system self-programmable Flash 8KB […]

Cluster HAT Interfaces up to 4 Raspberry Pi Zero to Raspberry Pi 2/3/4 Board

Cluster HAT is a solution to the problem of building cluster computing. Distributed computing is difficult already, and this tiny hardware kit is one answer to the problem. Although building a computer cluster is not that easy, it is one of the most impressive Raspberry Pi projects. Why Cluster HAT? The Cluster HAT (Hardware Attached on Top) interfaces a (Controller) Raspberry Pi A+/B+/2/3/4 with 4 Raspberry Pi Zeros. It is configured to use USB Gadget mode. Also, it is an ideal tool for teaching, testing or simulating small scale clusters. Cluster HAT leverages the flexibility of Raspberry Pi by allowing programmers to experiment with cluster computing. It is important you know that the HAT does not come with a Raspberry Pi or Pi Zero. The two are purchased separately. Pimoroni, the manufacturer, provides assembly and control instructions on its product page. Also, they explain 3 ways of setting up the […]

Turing Pi Clusterboard Takes up to 7 Raspberry Pi Compute Modules

We’ve already covered several cluster solutions based on Raspberry Pi boards such as Bitscope Blade with up to 40 Raspberry Pi boards, a 16 Raspberry Pi Zero cluster board prototype, Circumference “datacenter-in-a-box” with up to 32 Raspberry Pi 3 B+ boards. If you want something more compact, it makes sense to develop a platform with Raspberry Pi Compute Modules instead, and we’ve already published news about MiniNodes Raspberry Pi 3 CoM Carrier Board that supports up to to 5 Compute Modules 3/3+ last year. There’s now another option with Turing Pi Clusterboard support up to 7 Compute Modules for applications leveraging Kubernetes, Docker, Jupyter Notebook, machine learning (TensorFlow/Caffe), and serverless stack. Turing Pi specifications: 7x Sockets for Raspberry Pi Compute Module 3/3+ Storage – 7x microSD card slots Video Output – 1x HDMI port, MIPI DSI connector Audio – 1x 3.5mm audio jack Camera I/F – 2x MIPI CSI connectors […]

Ivport Stereo CM Breakout board for Raspberry Pi Compute Module Supports Two Cameras

We’ve previously written about IVport V2 camera multiplexer board that can connect up to 16 cameras to a single Raspberry Pi board in order to create 360 degrees camera setups for example. The company also offered a version with two cameras for stereo recording and capturing modes. But if you’d rather use a Raspberry Pi Compute Module with or without eMMC flash, and use either Raspberry Pi camera V1 or V2, the company has launched Ivport Stereo CM breakout board with support for up to two cameras and exposing some extra ports. Ivport Stereo CM specifications: RPi module compatibility Raspberry Pi CM1 Raspberry Pi CM3 (eMMC equipped) Raspberry Pi CM3 Lite Raspberry Pi CM3+ (eMMC equipped) Raspberry Pi CM3+ Lite RPi camera compatibility Raspberry Pi Camera Module V1.3 (OV5647 sensor) Raspberry Pi Camera Module V2 (Sony IMX 219 sensor) Storage – microSD slot Video Output – HDMI Networking – 10/100M […]

Microchip SAMA5 based Giant Board Launched on Crowd Supply for $50 and Up

Earlier this year we gave you details about some new development board, most especially about the Giant board. A tiny single board computer that runs Linux on Arm Cortex-A5 processor. This super tiny single-board computer (SBC) is based on the Adafruit Feather form factor. Unlike its name, the giant board is actually a small microchip. And it packs an awful lot of power for its size. The news is that it has launched on Crowd Supply for $50 and up. In addition, the giant board implements the power of size, which makes it unique. It squeezes SBC into a package the size of a microcontroller board. This will in turn relax memory, storage, and processing constraints. Consequently allowing you to effectively work on your projects. Another thing to know about the Giant Board is that it runs full Debian Linux. Giving developers and users access to an endless number of […]

Open Source ESP32 3D Printer Board Supports Marlin 2.0 Firmware

Espressif ESP32 processor was initially designed for cost-sensitive IoT projects thanks to its built-in WiFi & Bluetooth connectivity and low price, but the WiSoC’s fairly powerful two Xtensa cores found other uses such as face detection and audio applications among others. But a few people are now collaborating to bring ESP32 to the world of 3D printers with an open source hardware RepRap 3D printer controller board that has beta support in Marlin 2.0 RC1 firmware. There’s no commercially available ESP32 3D printer controller board right now, so only prototypes from the community are available. There are mainly two version of the boards: R1 and R2 designed by Simon Jouet, and at least one member – Felixstorm – made his own R2 board from the MIT licensed KiCad based design. R2 is a better design leveraging ESP32’s I2S interface to have more output pins and improve stepping. Felixstorm connected the […]

LEGO Minifigure shaped Mini SAM M4 Board Supports CircuitPython and Arduino

If you are a fan of the Lego movie. Perhaps you have always wanted to use Lego bricks to make something innovative and techy. Then the Mini SAM M4 board is here for you, as it is a LEGO minifigure-sized development board. Additionally, the design and layout of the board is based around the classic 1980’s ‘spaceman’, and is made by Ben Shockley. Although the board is very small, it has a lot of wonderful features. It comes with an analog reference decoupling/filtering capacitors. Also, it has an analog to digital ferrite bead, as well as a debounce circuitry for the reset and user buttons. Furthermore, the board’s software and firmware can be developed using CircuitPython or Arduino. The development board is either based on the Microchip SAMD51G 48-Pin 32-Bit ARM – Cortex M4F MCU (Mini SAM M4), or features the Microchip SAMD21G 48-Pin 32-Bit ARM Cortex -M0+ MCU running […]
