Most so-called breadboard-friendly boards that can easily be inserted into a breadboard often leave only one or two rows to play with on each side. This may suitable in many cases, but some people really want to use as many rows as possible, and come up with a solution using 90 degrees headers with 0.3″ spacing between them, just like 0.3″ wide chips do, and allowing the use of 4 rows on each side of the board. It does the trick, but this is not a standard solution, requires some bending of the headers, and covers part of the board so it’s not really ideal. A better way would be for somebody to design a narrow board using headers with 0.3″ spacing, and that’s exactly what Itaca Innovation has done with their Arduino Zero compatible uChip board designed in a 16-pin DIP package. uChip specifications: MCU – Microchip SAMD21 Arm […]
K3s Lightweight Kubernetes Distribution Targets Low Resources x86 and Arm Platforms
Kubernetes (K8s) is described as a “portable, extensible open-source platform for managing containerized workloads and services, that facilitates both declarative configuration and automation. It has a large, rapidly growing ecosystem. Kubernetes services, support, and tools are widely available. Google open-sourced the Kubernetes project in 2014”. However, as Rancher Labs’ CEO Sheng Liang explains “existing Kubernetes distributions are often memory intensive and overly complex for edge computing environments”, so the company developed and launched K3s, a lightweight Kubernetes distribution designed for developers and operators looking for a way to run Kubernetes in resource-constrained x86, Armv7-A and 64-bit Armv8-A hardware platforms often found in edge computing environments, as opposed to the cloud. Rancher Labs managed to reduce the footprint of Kubernetes, and better adapt it to entry-level hardware by taking four main steps: Removing old and non-essential code – Alpha functionalities, all non-default admission controllers, in-tree cloud providers, and storage drivers are […]
POWKIDDY X18 is a Low Cost Portable Android Game Console Powered by MediaTek MT8163 SoC
GPD XD Plus handheld Android game console launched about nearly one year ago with a MediaTek MT8176 hexa-core Arm Cortex-A72/A53 processor, and a 5.0″ display, and is now sold for under $210. But there’s now another portable game console that appears heavily inspired from GPD design, but featuring a low end MediaTek MT8163 quad core Cortex A53 processor instead, as well as a slightly larger 5.5″ display. Meet POWKIDDY X18.

$15 Sparkfun Edge Board Supports Tensorflow Lite for Microcontrollers
The 2019 TensorFlow Dev Summit is now taking place, and we’ve already covered the launch of Google’s Coral Edge TPU dev board and USB accelerator supporting TensorFlow Lite, but there has been another interesting new development during the event: TensorFlow Lite now also supports microcontrollers (MCU), instead of the more powerful application processors. You can easily get started with Tensorflow Lite for MCU with SparkFun Edge development board powered by Ambiq Micro Apollo3 Blue Bluetooth MCU whose ultra-efficient Arm Cortex-M4F core can run TensorFlow Lite using only 6uA/MHz. SparkFun Edge specifications: MCU – Ambiq Micro Apollo3 Blue 32-bit Arm Cortex-M4F processor at 48MHz / 96MHz (TurboSPOT) with DMA, 1MB flash, 384 KB SRAM, 6uA/MHz power usage, Bluetooth support. Connectivity – Bluetooth LE 5 (on-chip) + Bluetooth antenna Camera – OV7670 camera connector Audio – 2x MEMS microphones with operational amplifier Sensor – STMicro LIS2DH12 3-axis accelerometer Expansion – Qwiic connector, […]
GameShell Kit Review – Part 2: An Hackable Retro Gaming Console
ClockworkPi GameShell is an hackable retro gaming console combining Arm Linux and Arduino boards that happens to come in kit form, and that’s lot of fun to assemble as we’ve seen in the first part of the review of ClockworkPi GameShell. Since then I’ve had time to have more fun, play some games, and experiment with the device, so I’ll report my experience and point out the good parts, as well as some of the shortcomings I came across. We can press the power button to start it up, and after a few seconds we get to the main menu with several icons including… the self-describing Settings, Retro Games with MAME, MGBA, NESTOPIA, and PCxs emulators that require your own ROMs/BIOS, as well as Indie Games with ready to play games like OpenTyrian spaceship shooting game, or NyanCat. Moving on to the right of the menu we’ve got the famous […]
Seeeduino Lotus Cortex-M0+ is a $10 Arduino compatible Board with 12 Grove Connectors
Grove modules are cool little add-on boards that connect through 4-pin header using UART, I2C, analog or digital I/Os, and usually you’d need to buy a HAT or shield to connect them to respectively Raspberry Pi or Arduino board. But Seeed Studio has come up with a small Arduino compatible board based on Microchip SAMD21 microcontroller called Seeeduino Lotus Cortex-M0+ that may be the cheapest “Grove” solution around as it sells for just $9.90. Seeeduino Lotus Cortex-M0+ specifications: MCU – Microchip Atmel SAMD21 Arm Cortex-M0+ microcontroller at 48MHz with 256KB Flash and 32KB SRAM as found in Arduino Zero. USB – 1x micro USB port for power and programming Expansion 12x on-board Grove connectors (6x Digital, 3x Analog, 1x UART and 2x I2C) Arduino UNO headers 14x Digital I/O Pins (10 PWM outputs) 6x Analog Inputs I/O pins are 3.3V, do not input more than 3.3V, otherwise the CPU may […]
TI AM5729 Powered BeagleBone-AI Comes with TI C66x DSP and EVE Cores
Launched in 2013, BeagleBone Black is still one of the most popular hobbyist board thanks to its many I/Os, software support, and affordable price with being the cheapest board around those days. But it looks like we’ll soon have a new version that allows to experiment with artificial intelligence workloads. BeagleBone-AI is powered by Texas Instruments AM5729 SoC equipped with TI C66x digital-signal-processor (DSP) cores and embedded-vision-engine (EVE) cores supported through a TIDL (Texas Instruments Deep Learning) machine learning OpenCL API. BeagleBone-AI preliminary specifications: SoC – TI AM5729 dual core Cortex-A15 processor featuring 4 PRUs, Dual core C66x DSP, and 4 EVEs System Memory – 1GB RAM Storage – 16GB on-board eMMC flash with high-speed interface Networking – Gigabit Ethernet and high-speed WiFi SB – 1x USB type-C for power and superspeed dual-role controller, 1x USB type-A host Expansion – BeagleBone Black (BBB) compatible headers Dimensions – 86.4 x 53.4 […]
Snapdragon 8cx 5G Compute Platform Targets 5G always on, always connected PCs
Qualcomm announced Snapdragon 8cx processor for so-called always on, always connected mobile PCs in December 2018. The processor comes with eight Qualcomm Kryo 495 core, an Adreno 680 GPU with a 128-bit memory interface, NVME SSD, UFS 3.0 support, as well as a Snapdragon X24 4G LTE modem among other features. But the launch 5G cellular connectivity will start to (slowly) take off this year, so the company also revealed plans for Snapdragon 8cx 5G compute platform that brings the same processing power as 8cx processor but with an extra Snapdragon X55 5G modem. The company did not provide that many details about Snapdragon 8cx 5G in the press release, but we already know Snapdragon 8cx specifications as well as the key features of Snapdragon X55 2nd generation 5G modem, so we should already have a good idea about the platform. Qualcomm highlights the 7nm manufacturing process, multi-day battery life, and multi-gigabit […]
