RAK831 is a Semtech SX1301 based LoRa gateway module that was released by RakWireless in 2017. The board has since then be sold as part of the company’s LoRa gateway developer kit with a Raspberry Pi and a MAX-7Q GPS Module. But now RakWireless offers a nicely packaged solution with Raspberry Pi 3 board, RAK831 module, a GPS board, an enclosure, antenna, and power supply which they call RAK831 Lite, and sells for just $199 + shipping ($6.45 extra here).RAK831 Lite gateway main components and specifications: Main board – Raspberry Pi 3 development board with Broadom BCM2837 processor, 1GB RAM, micro SD card slot, Fast Ethernet, 4x USB ports, HDMI output, audio jack Connectivity RAK831 LoRa Concentrator board based on SX1301 chipset RF frequencies – 433, 470, EU868, AS923, AU915, and US 915 Rx Sensitivity – -140 dBm Tx Power – Up to 25.5 dBm at settings 27 dBm SMA […]
Tibbo-Pi is a Wirefree Modular IoT Prototyping Platform for Raspberry Pi Board
Tibbo Project System (TPS) is a modular Linux IoT prototyping platform based on the same Texas Instruments Sitara AM335x processor used in BeagleBone Black or a PocketBeagle boards, and comprised of a main board, Tibbit blocks to add features as needed, and an enclosure. I’ve now been informed the company will be at Computex 2018 to showcase their new products including Tibbo-Pi, following the same concept as Tibbo Project System, but leveraging Raspberry Pi 3 board and ecosystem instead. While an English brochure is said to be available, all information in the webpage listed in the photo above is in Japanese. But basically, Tibbo-Pi is said to be an IoT edge device for industrial use, made for build a prototypes, or small scale production system thanks to a choice a 60 different Tibbit Blocks sensor and I/O module blocks, all wire free. Programming of the system is typically done with with […]
Khadas Tone High Resolution Audio Board is Designed for Khadas VIM/VIM2, PCs, and Other SBCs
Khadas VIM and Khadas VIM2 are development boards powered respectively by Amlogic S905x and S912 processors that come with decent software support. The company also provides application specific add-on boards for their SBCs, and a while ago, I reviewed VIM2 with their dual tuner board and showed how to stream videos from my satellite dish or terrestrial antenna to the local network. Their latest solution is Khadas Tone board for high-quality audio applications. Khadas Tone “VIMs Edition” specifications: Multicore MCU – XMOS XU208-128-QF48 with 8x xCORE-200 cores up to 500 MIPS DAC – ES9038Q2M 32-Bit Stereo Mobile Audio DAC THD+N – ≤ 0.000337% @1KHz SNR – ≥ 120dB @ 10Hz~20KHz DNR – ≥ 120dB @ 10Hz~20KHz Crosstalk – ≥ 127dB @ 10Hz~20KHz Frequency Response – ±0.08 dB @ 10Hz~20KHz Sampling Frequency PCM: Up to 768KHz @ 32bit DSD: Up to DSD256 @ 1bit Clock Jitter Reference Clock Jitter < 3ps […]
Circumference Datacentre-in-a-Box Features up to 32 Raspberry Pi 3 B+ Managed by a UDOO x86 Ultra Board (Crowdfunding)
We’ve previously seen several clusters made of Raspberry Pi boards with a 16 RPi Zero cluster prototype, or BitScope Blade with 40 Raspberry Pi boards. The latter now even offers solutions for up to 1,000 nodes in a 42U rack. Circumference offers an other option with either 8 or 32 Raspberry Pi 3 (B+) boards managed by UDOO x86 board acting as a dedicated front-end processor (FEP) that’s designed as a “Datacenter-in-a-Box”. Key features and specifications: Compute nodes – 8x or 32x Raspberry Pi 3 B+ boards for a total of 128x 64-bit 1.4 GHz cores max Backplane MCU – Microchip ATmega1280 8-bit AVR microcontroller Serial Comms – FTDI FT4232 quad-USB UART Switched Mode Power Supply Units (SMPSUs): 8x / 32x software controlled (one per compute node) 1x / 4x always-on (microcontroller) HW monitoring: 8x / 32x compute node energy 2x / 8x supply voltage 2x / 8x temperature Remote […]
Pi-Hole Kit is a Raspberry Pi based Ad Blocker
If you don’t like getting tracked or see ads, it’s normally easy enough to install an ad blocker plugin in your web browser. But if you want to save some resources on your computer(s) and/or prevent online ads on other devices – including TVs – on your local network, it’s possible to do so via an external device / router using software such as Pi-Hole that can be installed on a Raspberry Pi board (or other Linux machines) in order to filter ads before they even get to your computer. This would normally require you to get your own hardware, enclosure, flash the firmware on a board, and install Pi-Hole yourself. That should easy enough for most regular readers of this blog, but there’s no an option for less tech-savvy user, as Pi Supply and Pi-Hole have partnered to launch the Pi Hole Kit with everything in one packages and […]
NeTV2 Open Video Development Board Works with Encrypted and Unencrypted Video Streams (Crowdfunding)
Chumby NeTV was an open source hardware Linux IPTV media player based on a Xilinx Spartan FPGA and a Marvell Armada 166 processor, and unveiled in 2011. Many years have passed since then, and now Bunnie Huang has come up with a new version. The NeTV2 development board is also optimized for open digital video application, but based on a more powerful Xilinx Artik-7 FPGA, and a Raspberry Pi 3 B+ can be added for things like seamless JTAG configuration and overlay video generation. Key features and specifications: FPGA – Xilinx Artik-7 XC7A35T-2FGG484 (available with XC7A50T option during campaign only) System Memory – 512 MB RAM, 32-bit wide DDR3-800 Storage – micro SD card, 8 MB SPI flash Video Ports 2x HDMI type A inputs 1 x HDMI type A output 1 x HDMI type D output.
