LoDev S76S Board Combines STM32, LoRa and Arm Mbed Support (Crowdfunding)

There are already plenty of low power boards with a LoRa radio, but Ronoth offers another option with their tiny LoDev S76S LoRa development board featuring AcSip S76S SiP (system-in-package) with STMicro STM32L073 microcontroller, a Semtech SX1276 LoRa radio, and other components. While most hobbyist LoRa boards are designed to be programmed with the Arduino IDE, LoDev S76S is instead compatible with Arm Mbed. LoDev S76S board specifications: SiP – AcSip S76S system-in-package with STMicro STM32L073 Arm Cortex-M0+ microcontroller @ 48 MHz with 192 kB flash, 20 kB RAM Semtech SX1276 chip supporting global 863MHz ~ 928MHz ISM Bands RF front-end LoRa Connectivity Receiver Sensitivity – down to -146 dBm TX Power – adjustable up to +20 dBm Range – up to 15 km coverage in suburban areas and up to 5 km coverage in urban areas SMA antenna connector USB – 1x micro USB port for programming and power […]

HiFive1 Rev B Board Gets FE310-G002 RISC-V Processor, WiFi & Bluetooth Module

SiFive launched what may have been the very first RISC-V development board in 2016 thanks to their HiFive1 Arduino compatible board powered by Freedom E310 (FE310) open source RISC-V processor. The company has now launched an upgrade version of the processor and board. Meet FE310-G002 processor and HiFive1 Rev B development board. HiFive1 Rev B development board specifications with new features highlighted in bold or stricken-through: MCU – SiFive Freedom E310-G0002 32-bit RV32IMAC processor @ up to 320+ MHz (1.61 DMIPS/MHz) Storage – 32 Mbit SPI flash (was 128 Mbit in the first version) Connectivity – ESP32-SOLO-1 WiFi & Bluetooth module I/Os 19x Digital I/O Pins 19x external interrupt pins 1x external wakeup pin 9x PWM pins 1/3 SPI Controllers/HW CS Pins I/O Voltages – 3.3V or 5V supported; note: bidirectional level shifters removed so FE310-G002 can drive the I/O pins directly at 3.3V only. USB – 1x micro USB […]

GRiSP 2 Board Targets Embedded Erlang & Elixir Development (Crowdfunding)

Erlang is described as a programming language used to build massively scalable soft real-time systems with requirements on high availability, and used in telecoms, banking, e-commerce, computer telephony and instant messaging. Elixir is a dynamic, functional language designed for building scalable and maintainable applications that leverages the Erlang VM, known for running low-latency, distributed and fault-tolerant systems. Elixir is used in many types of applications from higher-level web development to the embedded software domain, and Peer Stritzinger designed GRiSP board especially for the latter in 2017. He’s now back with GRiSP 2 featuring an NXP i.MX 6ULL SoM running Linux and RTEMS (Real-Time Executive for Multiprocessor Systems) RTOS. GRiSP 2 board is comprised of a system-on-module and baseboard with the following specifications: System on Module SoC – NXP iMX6UL Arm Cortex-A7 @ 696 MHz, 128 KB L2 cache, with TRNG, Crypto Engine (AES/TDES/SHA), Secure Boot Memory – 128 MB DDR3 […]

DIP-Sized uChip Arduino Zero Compatible Board Loves Your Breadboard (Crowdfunding)

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. POWKIDDY X18 hardware specifications: SoC – MediaTek MT8163 quad core Cortex A53 processor @ 1.3GHz with Arm Mali-T720 GPU System Memory – 2GB LPDDR3 Storage – 16GB eMMC flash, microSD card Display – 5.5″ IPS Screen with 1280 x 720 resolution, 5-point capacitive touchscreen Video Output – HDMI port Connectivity – WiFi 4 802.11 a/b/g/n, Bluetooth: 4.0 USB – 1x micro USB port (for charging only?)

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 […]
