How to Make a Low Cost DIY SD Card Duplicator

If you have to duplicate many SD cards for example to boot Raspbian on multiple Raspberry Pi board, one option is buy one of those SD card duplicators, but the problem is that they are not really cheap, for example the Systor 1-to-7 cards model sells for $540. Bob Brown, a retired senior lecturer, is now teaching K-12 students how to get started with Raspberry Pi boards, and must prepare bootable SD cards for his class. In order to save time, a duplicator would have been nice, but the price is too high, so instead he went with a DIY solution. You’ll first need some hardware, including a powered USB hub with the number of cards you want to duplicate, and corresponding SD card reader, and a larger micro SD card to hold Raspbian and/or other operating systems (optional, only for Raspberry Pi based duplicator). Mr. Brown made a 10-port […]

MCC 118 DAQ HAT Enables Up to 64-Channel Voltage Measurement on Raspberry Pi Boards

Measurement Computing Corp. (MCC) has recently introduced their MCC 118 DAQ HAT for Raspberry Pi which includes 8 analog inputs for voltage measurements between +/- 10V at a 100kS/s data rate. You can also perform data acquisition on up to 64 channels by stacking up to 8 MCC-118 DAQ HATs on top of a single Raspberry Pi board. The maximum throughput is limited to 320 kS/s. MCC 118 DAQ HAT key features & specifications: 8x 12-bit voltage inputs 100 kS/s max sample rate (320 kS/s aggregate for stacked boards) ±10 V input range Onboard sample buffers allow for high-speed acquisition External scan clock I/O External digital trigger input Screw terminal connections Up to eight MCC HATs are stackable on top of a Raspberry Pi board The data acquisition / data logger systems based on the add-on board would run Raspbian (Lite) on the Raspberry Pi board, as well as a […]

RockPro64 RK3399 Board Linux Review with Ubuntu 18.04 + LXDE

Let’s do one more RK3399 Linux review using Pine64 RockPro64 development board. After shortly checking out the hardware, I’ll test Ubuntu 18.04 “Bionic” LXDE on the board, test 3D graphics acceleration, video playback, USB storage and network performance among other things on the board. RockPro64 Board Unboxing The board came in a cardboard package, and the sticker made it clear I had received the 2GB LPDDR4 version. Even after FriendlyELEC NanoPi M4 announcement, Rockchip ROCKPro64 is still the cheapest RK3399 development board around, so it should come as no surprise that the board does not come with any accessories by default. Another way to keep the price low was not to include any built-in storage apart from SPI flash, so instead most people will either boot from micro SD card or an eMMC flash module both of which need to be purchase separately. Another cost-saving is the lack of built-in […]

UltraZed-EV Starter Kit Support Simultaneous 4K Encoding and Decoding with Xilinx Zynq UltraScale+ EV MPSoC

Xilinx unveiled Zynq UltraScale+ MPSoC‘s combining Arm Cortex A53/R5 cores with FPGA fabric back in 2015. and we started to see development boards and products based on the solution starting in 2017 with offerings such as AXIOM Board, TRENZ TE0808 SoM, or more recently 96Boards compliant Ultra96 development board. All last three boards have one thing in common: they all use an Zynq UltraScale+ GC MPSoC that adds a Mali-400MP2 GPU to CG MPSoC family. But there’s also a third EV family which standards for “Embedded Vision”, and adds support for 4K H.264 / H.265 hardware video codec capable of simultaneous encode and decode. The platform targets multimedia, automotive ADAS, surveillance, and other embedded vision applications. So far, I don’t think I had seen any boards based on Ultrascale+ EV MPSoC, but AVNet – following up on their UltraZed-EG starter kit – has now launched an UltraZed-EV starter kit powered […]

Arduino Releases Command Line Interface (CLI) Alpha Preview

So far, AFAIK the only official ways to program Arduino boards were through the Arduino IDE program, or the cloud-based Arduino Create which works in your web browser and does not require any installation on your computer. While graphical interfaces are nice and user-friendly, many of us are more productive while working using the command line, especially if commands can be scripted. So Arduino decided to work on a command line interface (CLI) for professional users, and have just announced a preview release. arduino-cli works in Windows, Linux, and Mac OS, and allows you install libraries, boards, and cores (e.g. esp32 Arduino core), compile the code, and upload the binary to the target board. If you want to get started quickly, you can download the binary “alpha” releases in the announcement board, but instead I opted to build the client myself as explained on Github. Everything below is done in […]

NanoPi M4 Raspberry Pi Inspired RK3399 Board Launched for $65 and Up

As expected, FriendlyELEC has now launched NanoPi M4 board, a lower cost version of NanoPC-T4 Rockchip RK3399 SBC, and mostly following Raspberry Pi form factor. How much you may ask? That would be $65 plus shipping for the 2GBRAM version, and $95 for the 4GB RAM version, which means it sells in the same ballpark as RockPro64 board. NanoPi M4 board specifications: SoC – Rockchip RK3399 big.LITTLE hexa-core processor with 2x Arm Cortex-A72 @ up to 2.0GHz, 4x Cortex-A53 @ up to 1.5GHz, a Mali-T864 GPU with support OpenGL ES1.1/2.0/3.0/3.1, OpenVG1.1, OpenCL, DX11, and AFBC, and a VPU with 4K VP9 and 4K 10-bit H265/H264 6decoding System Memory – Dual-channel 4GB LPDDR3-1866, or dual-channel 2GB DDR3-1866 Storage – eMMC module socket, micro SD card slot Video Output HDMI 2.0a up to 4K @ 60 Hz with HDCP 1.4/2.2 support 4-Lane MIPI-DSI connector Audio – 3.5mm headphone jack, HDMI digital audio […]

TableX Arm Linux Tablet Runs Armbian Ubuntu, To Launch for 89 Euros

If you want an Arm Linux laptop, you have already some choices with products such as Pine64 Pinebook, or Olimex TERES-I open source hardware laptop, but if instead you’d rather do without keyboard, and get an Arm Linux tablet, choices are much more limited, if any at all. Back in 2012, Allwinner A10 based PengPod 700 & 1000 tablets were available for the company has since folded, and this year, RasPad case launched to allow you to build your own thick tablet with a Raspberry Pi 3 (B+). However, if you want to normal looking tablet, your best option right now is to get an Android tablet and mess around to install Linux on it. That’s not for everyone, and the good news is that what looks like a proper – albeit low-end – Arm Linux tablet is coming to market soon with TableX. TableX preliminary hardware specifications: SoC – […]
