SiFive Launches 32-bit E31 Coreplex & 64-bit E51 Coreplex RISC-V Processors, Reveals Pricing

SiFive unveiled their Freedom U500 and E500 open source RISC-V SoCs last year, and a little layer launched HiFive1 Arduino compatible development board based on SiFive Freedom E310 processor. The company has now launched their non-open source Coreplex IP also based on RISC-V ISA with the 32-bit E31 Coreplex and 64-bit E51 Coreplex, and explained details about pricing. Some of the key features of the processors are listed below: E31 Coreplex 32-bit RV32IMAC core @ 900 to 1.5 GHz (with 28nm process) Advanced Memory Subsystem – 16KB, 2-way Instruction Cache, Instruction Tightly Integrated Memory (ITIM) option, up to 64KB Data Tightly Integrated Memory (DTIM) support Up to 16 local interrupts with vectored addresses Performance – 1.61 DMIPS/MHz  ; 2.73 Coremark/MHz Power Consumption 28nm HPC process – Core only: 150 DMIPS/mW ; Coreplex: 41 DMIPS/mW 55nm LP process – Core only: 95 DMIPS/mW; Coreplex: 16 DMIPS/mW Applications: Edge Computing, Smart IoT […]

SinoVoIP Releases $35 Banana Pi BPI-M2+ Board with Allwinner H2+ Processor

Banana Pi BPI M2+ board was first released with Allwinner H3 processor, but the same PCB can also be used with Allwinner H2+ and H5 processors since the processors are pin-to-pin compatible, and SinoVoIP intends to release three version of the board, and just launched BPI M2+ (aka BPI H2+) with Allwinner H2+ processor for $34.50 + shipping, $1.5 cheaper than the H3 version also listed on Aliexpress. If you shop around, and don’t order on the official SinoVoIP store, you may find cheaper price for the boards. As expected, the specifications have not changed apart from the processor: SoC – Allwinner H2+ quad core Cortex A7 @ 1.2 GHz with an ARM Mali-400MP2 GPU up to 600 MHz System Memory – 1GB DDR3 Storage – 8GB eMMC flash, micro SD card slot up to 64GB, Video & Audio Output – HDMI with CEC support Connectivity – Gigabit Ethernet, 802.11 […]

VolksPC OS Runs Android and Debian Simultaneously on ODROID-C2 Board

Most development boards and some TV boxes offer a dual boot image with Android and a Linux distribution. To run an Android app, you need to boot to Android OS, and if you decided you need to run Linux, you then need to reboot to the Linux OS, and you can’t simply use Alt+Tab to easily and quickly switch between Android and Linux apps. But VolksPC offers just that: the ability to run Android and Debian side-by-side, and I tested their MicroXWin unified distributions with MK808B TV stick powered by Rockchip RK3066 processor a few years ago. It was early stage at the time (July 2014), and there was some stability issues.The company has kept working on their solution, but focused on more powerful hardware, and they have now released VOLKSPC OS for ODROID-C2 with Debian XFCE and Android Marshmallow, which will run both Android and Debian applications at the […]

$97 MXQ HF10 Android Bluetooth Speaker & TV Box Works with Amazon Alexa

Last fall, I wrote about Eny Technology HF10, a 2-in-1 Android 6.0 TV box & Bluetooth speaker powered by Amlogic S905X processor, but at the time it was still under development, and we did not know all the features. The device has now been launched under the MXQ brand with support for Amazon Alexa voice service, and is up for pre-order for $96.55 on GearBest. MXQ HF10 specifications: SoC –  Amlogic S905X quad core ARM Cortex-A53 @ up to 1.5 GHz with Mali-450MP GPU System Memory – 1GB DDR3 Storage – 8GB eMMC flash + micro SD slot up to 128 GB Video Output – HDMI 2.0a up to 4K @ 60 Hz Audio HDMI output 2.5″ 10W mono bass speaker with class-D amplifier Connectivity – 10/100M Ethernet, dual band 802.11 b/g/n/ac Wi-Fi, and Bluetooth 4.0 USB – 1x USB 2.0 host port Misc – Power & Play/Pause combo button, […]

$59 HDFury Universal PSU Doctor Supports Power Monitoring via iOS or Android

We’ve recently covered Cambrionix PowerPad 15S, a high-end 16-port USB hub that can deliver 5V/2.1A on each port, integrates power monitoring function, and an API to control and monitor each port individually. That’s a very cool device, but it’s also expensive at around $600, and even the cheaper PowerPad 15C without data pins, come at $200. If you don’t need the complete set of features offered by Cambrionix devices, but you’ll like to get a reliable multi-port USB charger with power monitoring function, HDFury Universal PSU Doctor could be an interesting option. HDFury Universal PSU Doctor specifications: MCU – Renesas RL78 16-bit MCU USB – 3x USB ports with 2x 5V ports up to 5V/2.14A, 1x USB QC 2.0 port supporting 5V/2.14A, 9V/1.6A or 12V/1.2A output ADC – Up to 11 channels, 10-bit resolution for power monitoring Sensor – n-chip temperature sensor Power Supply Built-in 100 ~ 240V AC with […]

Google Assistant SDK Turns Your Raspberry Pi 3 into Google Home

Google Home allows you to select music, control your home automation system and more with voice commands, but now you can do the same with a Raspberry Pi 3 as Google released a developer preview (alpha v1) of the Google Assistant API that works on Raspberry Pi 3, and other development boards running Debian or Ubuntu. Functionalities are limited right now, with RPC API and Python sample code, but it only works with English language, and features such as timers & alarm, playing music, news, or podcasts, and precise location are not supported. Location is determined using your IP address only, and if you’re using some third party services / products such as Uber or Hue, you’ll need an actual Google Home device for initial setup. Google has provided instructions to use Google Assistant SDK with Raspberry Pi 3 board. First you’ll need a USB microphone ($5.99 on Amazon), and […]

ZX Spectrum Next Retro Keyboard PC Relies on Xilinx FPGA, Raspberry Pi Zero “Accelerator” Board (Crowdfunding)

ZX Spectrum keyboard computer was launched in April 1982 in the United Kingdom, and 35 years later, a team of developers has now been working on ZX Spectrum Next somewhat resuscitating ZX Spectrum by emulating Z80 processor in a Xilinx FPGA, using an optional Raspberry Pi Zero board as an accelerator, and adding some modern features like HDMI output and WiFi. While the case is only a 3D rendering for now, they have a working board prototype with the following specifications: FPGA – Xilinx Spartan-6 FGPA emulating Z80 processor in 3.5Mhz and 7Mhz modes System Memory – 512KB RAM (expandable to 1.5MB internally and 2.5MB externally) Storage – SD Card slot, with DivMMC compatible protocol used in the original ZX Spectrum Video Hardware sprites, 256 colours mode, Timex 8×1 mode etc. Output: RGB, VGA, HDMI Audio – 3x AY-3-8912 audio chips with stereo output + FM sound Networking – Optional […]

Whitecat ESP32 N1 Board Combines ESP32 WiFi + Bluetooth SoC with a LoRa Transceiver, Runs Lua RTOS

Espressif ESP32 SoC is gaining traction right now as prices have come down, and there’s still an on-going fight among LPWAN standards with LoRaWAN being fairly popular in Europe. Whitecat, a group of engineers from several companies based in Citilab, Barcelona, Spain, has designed a board that combines both ESP32 and a LoRA transceiver, bringing an alternative to Pycom LoPy board, but instead of running MicroPython, they have developed Lua-RTOS. Whitecat ESP32 N1 hardware specifications: SoC – Espressif ESP32 dual-core Tensilica LX6 microprocessor @ up to 240MHz with 520kB internal SRAM Storage – 4MB flash memory Connectivity LoRa WAN transceiver working in the 868 (EU) MHz / 915 (USA) MHz with on-board antenna, and u.FL connector for external antenna Integrated 802.11b/g/n WiFi transceiver with on-board antenna, and u.FL connector for external antenna Integrated dual-mode Bluetooth (classic and BLE) I/O Headers – 2x 16-pin with SPI, I2C, I2S, SDIO, UART, CAN, […]
