Top 5 Most Powerful Arm SBCs & Development Boards in 2017 / Early 2018

Raspberry Pi, Orange Pi, and NanoPi boards among others are all great and inexpensive Arm Linux development boards that do good enough job for many tasks, but they may not cut it if you have higher requirements either in terms of CPU power, GPU capabilities and performance, I/O bandwidth, and in some cases software and support. So I’ve decided to make a list of 5 single board computers or development boards that I consider to be the most powerful in 2017, early 2018. I have limited the price to $1,000 maximum, the board must be easy to purchase for most people (e.g. you don’t need to be a tier-1 automotive supplier, or operate your own datacenter), and in case the board is not quite available yet, the likeliness of actual launch must be reasonably high. Those criteria for example exclude Intrinsyc Open-Q 835 development kit since it costs $1.149 and […]

Amazon FreeRTOS Released for NXP, Texas Instruments, STMicro, and (soon) Microchip Microcontrollers

FreeRTOS is an open source real-time operating system for microcontrollers released under an MIT license, and when it comes to adoption in embedded systems it’s right there near the top with embedded Linux according to Aspencore 2017 embedded markets study. For example, some Espressif SDKs for ESP8266 or ESP32 are based on FreeRTOS, and so is Mediatek LinkIt Development Platform for RTOS. The recently announced Amazon FreeRTOS (a:FreeRTOS) leverages the open source operating systems, and extends it with with libraries that enable local and AWS cloud connectivity, security, and soon over-the-air updates. a:FreeRTOS is free of charge, open source, and available today. In order to get started, you’ll have a choice of 4 hardware platforms: STMicro STM32L4 Discovery Kit IoT Node (B-L475E-IOT01A) powered by STM32L475 ARM Cortex-M4 MCU with 802.11 b/g/n WiFi, Bluetooth 4.1 LE, RF (868 / 915 MHz), and NFC connectivity, plenty of sensors NXP LPC54018 IoT module (OM40007) […]

Xiaomi Unveils Their Very Own ESP32 Development Board, Module & SDK

We now have plenty of modules and board based on Espressif System ESP32 dual core wireless SoC, and a fairly good software support with ESP IDF SDK, Arduino Core,  MicroPython, Espruino and other solutions. So I was surprised when I saw Teo Swee Ann, Espressif CEO, posted photos about an event – Xiaomi IoT Developer Conference – where Xiaomi apparently introduced their own ESP32 development board, together their own SDK (still empty right now) compatible with the company’s Mijia ecosystem, as part of their “Open IoT platform” The slide below translates as “WIFI module –  Automated manufacturing / 4-fold foolproof mechanism / whole process tracing / cost price (about 15 RMB)” and “Open source SDK”, with the price likely the price of Xiaomi ESP32 module (ESP-WROOM-32C) shown on board above (Thank to hm for translation). I could not find much information at this early stage, except new partnership between Baidu […]

Armbian v5.35 Released with Linux 4.13, U-boot v2017.09, New Boards Support

Armbian v5.35 has been released last Friday as a major update that brings Linux mainline kernel to version 4.13, U-Boot mainline to version v2017.09, adds support for 7″ Raspberry Pi display, Realtek WiFi drivers (mainline), and new stable hardware support for NanoPi Duo, Pinebook, and Orange Pi R1. Some other boards got experimental support, including Le Potato, NanoPi NEO 2, Orange Pi Zero Plus, Orange Pi Zero Plus 2 (H5). The desktop version of the images gets a full featured XFCE terminal, OpenVPN connector, a new wallpaper, and various other changes and fixes. armbian-config is normally used to configure the board for example networking configuration, but the utility has become even more useful with support for Hotspot, Bluetooth, SSH server configuration, swtich between stable & beta builds and between kernel applications, adds the ability to start an RDP server, and install third party software such as SAMBA, OpenMediaVault, PiHole, Transmission […]

Gameshell Portable Retro Gaming Console Features Clockwork Pi Allwinner R16 Board (Crowdfunding)

Allwinner R16 with its lowly four Cortex A7 cores and Mali-400MP2 GPU would not normally come to mind when designing a gaming console. But Nintendo used the R16 processor twice in their retro gaming consoles: NES Classic and SNES Classic Edition. Clockwork, a startup based in Hangzhou, China, decided they could also do gaming console with the processor: Gameshell. But their product is quite different, as it’s both a portable console with 2.7″ display, and a development platform with the console based on Clockwork Pi development board, and an Atmel AVR (Arduino) based keypad board. Gameshell specifications: Clockwork Pi development board SoC – Alwinner R16-J quad core Cortex A7 processor @ 1.2 GHz with Mali-400MP2 GPU System Memory – 512MB or 1GB (in future revision of the board) Storage – 1x micro SDHC slot Video Output / Display I/F – 18-bit RGB display interface, micro HDMI (planned in revision of […]

Detect Lightning with Those AMS AS3935 “Thunder” Boards

Launched in 2012, AMS AS3935 Franklin lightning sensor  is – at its name implies – a lightning sensing IC. The chip was designed for low power, portable or fixed wire-line applications, and beside detecting electrical emissions from lightning activity, it can also provide an estimation of the distance to the head of the storm from 40km away down to 1km, while filtering out other signals from motors, microwave ovens, etc… The chip interfaces via SPI or I2C to the host processor / micro-controller, and comes in a small MLPW-16 (4x4mm) package. Price is $3.55 per unit for 1k orders. Applications include wearables, golf carts, pool safety, portable GPS, bike computers, weather stations, uninterruptible power supplies, smart grid systems, environmental monitoring systems, etc… Basically, AS3935 can be used either for weather monitoring, or safety applications. I’ve found two maker boards with the chip: MikroElectronika Thunder Click board compatible with MikroBUS socket […]

VoltaStream AMP1 Linux Audio Board Includes a Stereo Audio Amplifier, Adds WiFi and Bluetooth

Last summer I wrote about VoltaStream ZERO an audio board powered by NXP i.MX6ULL processor, with up to 1GB RAM, a Texas Instruments DAC, and leveraging Raspberry Pi Zero form factor. The board runs a custom Linux distribution called PolyOS built with the Yocto Project, and including shairport-sync, librespot, SqueezeLite, a DLNA renderer, and more. Polyvection, the company behind the project is now back with VoltaStream AMP1 audio development board, with half the board very similar to VoltStream ZERO, and the other half featuring an audio amplifier, and a wireless module for WiFi and Bluetooth. VoltaStream AMP1 board specifications: SoC – NXP i.MX6ULL ARM Cortex-A7 processor @ 996 MHz System Memory – 512 MB DDR3 Storage – micro SD card slot Audio 1x I2S for integrated DAC and AMP, 1x I2S for GPIO access, 1x TOSLINK-IN jack Analog DAC – Texas Instruments PCM1862 (SNR 103 dB) Amplifier – ISSI IS31AP2121 […]
