Minnow Server is a Secure Web Server for Microcontrollers

Many embedded systems have a limited amount of memory, which would normally run programs with smaller footprints than on desktops or servers. For example, nginx and Apache2 are the common web servers, but on hardware with limited memory, smaller footprint web servers may be required, so that’s why I wrote a list of web servers for embedded systems running Linux/uClinux many years ago. But now, even platforms based on microcontrollers often need to run web server usually for configuration. We’ve already shown how to use Arduino to serve a simple web page and did the same in Getting Started with NodeMCU Board Powered by ESP8266 WiSoC but using Lua programming language instead. It may be more convenient to run a proper web server however, as it’s easier to change the interface, and we previously covered MicroWebSrv lightweight web server that works on platforms running MicroPython such as Pycom boards. Real Time […]

Orange Pi RK3399 Board Gets 4GB RAM for $100

Orange Pi RK3399 development board launched last year, further crowding the RK3399 space. The board did not target the lower end of the market with a $109 price tag, but still came with only 2GB of RAM. Shenzhen Xunlong has now introduced a 4GB RAM version of the board for $99.96, with the 2GB version now selling for $89.38. Both boards can be purchased on Aliexpress. Apart from the RAM capacity, Orange Pi RK3399 “4G” specifications have not changed: SoC – Rockchip K3399 hexa-core big.LITTLE processor with two ARM Cortex A72 cores up to 2.0 GHz, four Cortex A53 cores, and an ARM Mali-T860 MP4 GPU with support for OpenGL 1.1 to 3.1 support, OpenVG1.1, OpenCL, and DX 11 System Memory – 4 GB DDR3 Storage – 16 GB eMMC flash, micro SD card, mPCIe (for mSATA/LTE), and SATA interface Video Output/Input & Display Interfaces 1x HDMI 2.0 up to […]

Tiny Giant Board Runs Linux, Follows Adafruit Feather Form Factor

If you want a tiny single board computer that runs Linux on Arm Cortex-A processor, some options include Raspberry Pi Zero (W), PocketBeagle, or FriendlyElec NanoPi Duo with the latter being smaller and more powerful than RPi Zero although it lacks video output. Another potential option that may become available soon is the Giant Board, which as its name clearly does not imply, is a really tiny board powered by Microchip Atmel SAMA5 Cortex-A5 processor, and leveraging Adafruit Feather form factor. Giant board preliminary specifications: SiP – ATSAMA5D27C-D1G with Microchip SAMA5D2 Arm Cortex-A5 Processor 500MHz, 128MB DDR2 RAM Storage – Micro SD slot for OS and storage Peripherals & I/Os 6x 12-Bit ADC with 3.3V Reference 4x 16-Bit PWM ADC external trigger PWM external trigger 1x I2C, 1x SPI, 1x UART Misc- Power button Power Supply 5V via micro USB port 3.7V LIPO support for portable projects The Microchip / […]

tinyWiFi-5G is a NanoPi NEO Air Clone with 5 GHz WiFi

NanoPi NEO Air is a tiny Allwinner H3 board with 802.11 b/g/n WiFi connectivity that launched in 2016 for $17.99 and is now available as NanoPi NEO Air-LTS (Long Term Support) for $28 and up. A company – or group of software developers – called tinyDebian decided to create a clone based on NanoPi NEO Air design, but replacing the 2.4 GHz Ampak AP6212 802.11n WiFi + Bluetooth 4.0 LE module by a dual-band Realtek RTL8821CS module that supports 802.11 b/g/n/ac and Bluetooth 4.2 LE. Meet tinyWiFi-5G. NanoPi NEO Air comes with two different storage configuration (8GB or 32GB flash), but tinyDebian did not provide the full specifications of the board, so tinyWiFi-5G board specifications below are preliminary: SoC – Allwinner H3 quad-core Cortex A7 @ 1.2 GHz with an ARM Mali-400MP2 GPU System Memory – 512 MB DDR3 Storage – 8GB eMMC Flash + micro SD card slot Connectivity […]

Cosmo Communicator 2-in-1 Smartphone & Pocket Computer Runs Android 9, Linux

In recent years, we’ve started to see Windows 10 mini laptops with 6″ to 8″ display and a foldable keyboard coming to market thanks to products such as GPD Pocket 2 or One Mix 2 Yoga. They offer a full Windows 10 experience in an ultra-small form factor, but you’d still need to carry your phone around with you for things like calls or SMS. Cosmo Communicator offers a similar experience, but instead of relying on Intel processor and Windows, the device comes with a Mediatek P70 mobile processor capable of running Android 9 Pie or Linux distributions merging phone and mini laptop functionalities into a single device. Cosmo Communicator preliminary specifications: SoC – Mediatek P70 octa-core processor with four Arm Cortex A73 cores @ up to 2.0GHz, four Cortex A53 cores @ up to 2.0GHz, Arm Mali G72 MP3 GPU @ 800MHz, and a Dual-core mobile AI processor (APU) […]

V-Raptor is a 24-Core Arm Server based on SocioNext SC2A11 SoC

Socionext SC2A11 24-core Arm Cortex-A53 processor has gotten into more hardware recently. We recently showcased a demo of an upcoming Banana Pi 24-core Arm server, but they’ll be joined by South Korea based XSLAB which prepare to launch their own V-Raptor 24-core microserver in February 2019. The server is based on SC2A11 processor coupled with their own BMC (Baseboard Management Controller). A 24-core micro server node is shown below with SC2A11 processor covered by a black heatsink, as well as a RAM stick. As I understand it, one or several V-Raptor microserver can then be inserted into a PCIe slot of the mainboard which supports up to 32 nodes on 2U rack size, so that would be a total of 24 x 32 = 768 Arm Cortex A53 cores. The detailed specifications of the server are not shown yet on the almost empty company website. The company may also have made […]

A Look at a Small NanoPi NEO4 Build Farm

FriendlyElec NanoPi NEO4 is currently the cheapest and smallest SBC powered by Rockchip RK3399 hexa-core processor which packs two Cortex A72 “fast” 64-bit cores, and four Cortex-A53 “efficiency” cores, so it should be an obvious candidate if you plan on building an Arm build farm costs to its low cost, small form factor, and relatively good performance. As part of his work on HAProxy load balancer, Willy Tarreau often has to run time-consuming builds for Arm targets, and to speed up the builds he’s put together several Arm based build farms powered by low cost development boards / SBCs. Up to now he had a build farm powered by five MIQI boards featuring Rockchip RK3288 processor with four Cortex-A17 “fast” 32-bit processor, and controlled with a ClearFog Pro networking board. He’s now decided to build another similar build farm but with NanoPi NEO4 boards instead. Willy goes through the hardware […]
