balenaFin Developer Kit Review – Part 1: Unboxing and Assembly Instructions

Balena launched balenaFin 1.1 at the end of last month. The board is a professional carrier board for Raspberry Pi Compute Module 3 / 3+ Lite that includes support for variable voltage power input, optional PoE, industrial eMMC flash storage, a real-time Arm Cortex-M4 core via Artik-020 module, and more. Somehow a balenaFin 1.1 developer kit ended up in my home, and I’ll play with it in several weeks, but in the first part of the review, I’ll just check out the content of the package, and show how to assemble the kit. BalenaFin 1.1 Developer Kit Unboxing The local courier brought a largish balena Fin package. which contained a smaller balenaFin package, and the actual developer kit. Everything is nicely packaged in the box with the part related to power supply in a white box, a small opening for smaller accessories and Raspberry Pi Compute Module 3, as well […]

Google to Launch Edge TPU Powered Coral Development Board and USB Accelerator

Several low power neural network accelerators have been launched over the recent years in order to accelerator A.I. workloads such as object recognition, and speech processing. Recent announcements include USB devices such as Intel Neural Compute Stick 2 or Orange Pi AI Stick2801. I completely forgot about it, but Google also announced their own Edge TPU ML accelerator, development kit, and USB accelerator last summer. The good news is that Edge TPU powered Coral USB accelerator and Coral dev board and are going to launch in the next few days for respectively $74.99 and $149.99. Coral Development Board Coral dev board is comprised of a base board and SoM wit the following specifications: Edge TPU Module SoC – NXP i.MX 8M quad core Arm Cortex-A53 processor with Arm Cortex-M4F real-time core,  GC7000 Lite 3D GPU ML accelerator – Google Edge TPU coprocessor delivering up to 4 TOPS System Memory – […]

TechNexion AXON and FLEX SoM Families Feature i.MX 8M Mini SoC, FPGA Fabric

Taiwan based Technexion has introduced several new products at Embedded World 2019 including two new SoM families: AXON and FLEX. AXON is a product family of small form factor (58 x 37 mm) modules designed for specialized embedded applications requiring extra I/O flexibility, while FLEX series is a low-cost family making use of the standard LPDDR4 SO-DIMM connector. Specifically, the company launched new AXON and FLEX modules powered by NXP i.MX 8M Mini processor with AXON-IMX8M-MINI featuring AXON Fabric programmable logic, a specialized IC that provides additional functions including nearly infinite pinmuxing, and FLEX-IMX8M-MINI that offers HD multimedia streaming and integrated 3D graphics for cost sensitive applications. AXON-IMX8M-MINI SoM AXON-IMX8M-MINI SoM specifications: SoC – NXP i.MX 8M Mini Solo, Dual or Quad Arm Cortex-A53+M4 processor FPGA – “Axon Fabric” making use of a Lattice MachXO3LF FPGA with 2100 LUTs (LookUp Tables) System Memory – Up to 4GB LPDDR4 RAM Storage […]

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 […]

Systems-on-Module Market Update – An Interview with Toradex CMO

I’ve been interviewing Daniel Lang, Toradex Chief Marketing Officer (CMO), over email just before Embedded World 2019, to learn a bit more about the system-on-module market, and what’s ahead. CNXSoft: We’ve already covered several Toradex systems-on-module and development kits on CNX Software, but for readers who may not know Toradex yet, could you provide a short description of what the company does in the embedded systems space? Daniel Lang: Thanks for having me. Toradex builds high reliable Arm-based System on Modules. Our focus is to make the life of developers easier and to reduce the complexity and time-to-market. We sell hardware, but most of our engineering resources focus on Software and Support. Our products are used in areas such as Industrial Automation, Medical, Transportation, Test and Measurement, Building Automation and many more. CNXSoft: Could you explain why / what type of customers go the SoM route instead of designing for […]

STMicro STM32MP1 Cortex A7/M4 MPU Supports Linux and Android

When Linux 4.17 was released last June, we discovered an interesting new STM32 part: STM32MP157C dual core Cortex-A7 processor. It was the first time I saw an STM32 IC not based on Arm Cortex-M microcontroller core, but we knew only very little details at the time. STMicro has now made it official, and introduced STM32MP1, the first STM32 MPU (Microprocessor Unit) that features one or two Arm Cortex-A7 cores running Linux, as well as an Arm Cortex-M4 real-time core that allows to re-use code from existing STM32 projects. STM32MP1 key features and specifications: Cores Single or Dual Cortex-A7 core(s) running at 650 MHz with 32-Kbyte L1 Instruction cache, 32-Kbyte L1 Data cache, 256-Kbyte Level 2 cache Cortex-M4 core running at 209 MHz with single-precision floating point unit (FPU), digital signal processor (DSP) instructions, and memory protection unit (MPU) GPU (STM32MP157 only) – Vivante 3D GPU with OpenGL ES 2.0 support; […]

Arduino IoT Cloud Public Beta Launched

It’s long been possible to get data from sensors connected to official or compatible Arduino board, upload it to some cloud services, and watch the results is a neat web interface. But until now, you had to rely on third party services such as ThingSpeak, Adafruit.io, or Thinger.io to name a few. Arduino has now announced their own Arduino IoT Cloud services is entering public beta. You’d normally need to modify the sketch by hand to connect an Arduino board to the cloud, but Arduino IoT Cloud can automatically generate a sketch when setting up a new project, and help you get started quickly in less than five minutes. The Arduino IoT Cloud supports HTTP REST API, MQTT, Command-Line Tools, Javascript, and Websockets, and devices are secured using X.509 certificate-based authentication. To get started, you’ll need an Arduino MKR board, and create an account or login to Arduino IoT Cloud. […]

postmarketOS Linux Mobile OS Supports Over 100 Devices

postmarketOS is a Linux operating system that was first unveiled in 2017, with the developers aiming to provide long term support in order to extend the life of existing phones.  The operating system is based on Alpine Linux with touch-screen optimization, and the goal is to provide updates, including security updates, for at least 10 years just like you would get on a computer. The project was really getting started at the time, but now the community has provided an update for the first 600 days of development, and over 100 devices are now supported, mostly smartphones such as Google Pixel 3 XL or Motorola Droid 4, but also some SBCs, for instance, Pine A64-LTS and various Raspberry Pi boards. “Supported” means the 112 devices listed can boot postmarketOS, but the operating system is still considered to be alpha software, and for example, if you look at the features matrix […]
