Waveshare Launches an Affordable 7-Color e-Paper Display

Most e-paper displays are black or white with sometimes red or yellow color being added to the mix. But E-Ink has recently launched several color e-Paper display at prices that will not make it affordable to most projects. Waveshare has launched its fair share of e-Paper displays in the past, and now the company is coming with a relatively affordable 5.65″ color e-Paper display with seven different colors for $74.99 plus shipping. Main features and specifications: Display 5.65″ display (114.9 × 85.8mm) Resolution – 600 × 448 pixels Viewing angle – >170° ACeP (Advanced Color ePaper) 7-color with black, white, green, blue, red, yellow, and orange Greyscale – 2 levels Full refresh time – 15s Dot pitch – 0.1915 × 0.1915mm Host Interface – 3-wire SPI or 4-wire SPI Operating voltage – 3.3V/5V Power Consumption 50mW (typ.) during refresh Standby current – <0.01uA (almost none) Dimensions – Board – 138.5 […]

ODYSSEY-X86J4105 Gemini Lake & Arduino SBC Review with Windows 10 Enterprise

I’ve recently received ODYSSEY-X86J4105 SBC with Re_Computer case, and we’ve had a look at the SBC hardware, installed some internal components like an M.2 SATA SSD, and play around Re_Computer case using Raspberry Pi 4, Beaglebone Green Wireless and Jetson Nano SBC, before assembling the Intel SBC into the enclosure. I’ve now taken the time to test the combo using the pre-installed Windows 10 Enterprise operating systems. ODYSSEY-X86J4105 is very much like any Intel Gemini Lake mini PC, but with the addition of Arduino and Raspberry Pi headers, so we’ll look at those as well. Connections and First Boot For the first boot, I connect USB mouse and keyboard, a HDMI cable to a 4K TV, an Ethernet cable, a USB 3.0 hard drive, and finally the power supply. I actually had a small problem during boot, but we’ll talk about it later as it’s really specific to my setup, […]

ODROID-N2 Plus SBC Gets Amlogic S922X Rev. C Processor Clocked at up to 2.4 GHz

Announced in February 2019, ODROID-N2 Amlogic S922X SBC launched the following month with 2GB to 4GB RAM, HDMI 2.0 output, Gigabit Ethernet, multiple USB 3.0 ports with pricing starting at $63 making very good value for an hexa-core Cortex-A73/A53 processor. The company has now announced an upgraded with ODROID-N2 Plus SBC featuring Amlogic S922X Rev.C bringing the Cortex-A73 big core maximum clock frequency from 1.8 GHz to 2.2GHz. But Hardkernel also found out they could overclock the processor up to 2.4 GHz in all 300 boards they have delivered a 33% boost over the original ODROID-N2 board. The Cortex-A53 cores are also a bit faster up to 2.0 GHz. ODROID-N2+ specifications: SoC – Amlogic S922X Rev.C hexa-core big.LITTLE processor with 4x Arm Cortex A73 cores @ up to 2.2/2.4GHz, 2x Arm Cortex A53 cores @ 2.0GHz, Arm Mali-G52 GPU @ 846MHz; 12nm manufacturing process System Memory – 2GB or 4GB […]

ODYSSEY-X86J4105 SBC Unboxing and Re_Computer Case Review

Seeed Studio ODYSSEY-X86J4105 is an Intel Celeron J4105 Gemini Lake SBC that also happens to integrate an Arduino compatible Microchip SAMD21 Arm Cortex M0+ microcontroller that makes it suitable as an all-in-one Arduino platform. But it can do much more with 8GB RAM, an optional 64GB eMMC flash, HDMI & USB-C DisplayPort 4K video outputs, dual Gigabit Ethernet, and support for both SATA and NVMe storage. The board runs Windows 10 Enterprise by default (if you purchase the board with an eMMC flash), and supports Linux distributions as well. Seeed Studio sent me a review sample, so I’ll start by checking out the hardware first. ODYSSEY-X86J4105 Unboxing I received ODYSSEY-X86J4105864 with a built-in 64GB eMMC flash pre-loaded with Windows 10 Enterprise. Let’s have a quick look at the board with USB, Ethernet and video output ports previously described, as well as built-in dual-band Wi-Fi 5 & Bluetooth 5.0 module, and […]

Sipeed TANG Hex is a Low-Cost Xilinx Zynq-7020 Arm FPGA Board

Last year, Sipeed launched a $5 FPGA board called Sipeed Tang and based on an entry-level Gowin GW1N-1-LV FPGA. But I had not noticed the company had also worked on a more powerful, yet still low-cost Xilinx Zynq-7020 board in a business card form factor not too dissimilar from the Raspberry Pi model B form factor. Meet Sipeed TANG Hex. So far a low-cost Zynq-7010 or Zynq-7020 board met you had to spend $99 to $199 with products such as MyIR Z-Turn and Digilent PYNQ-Z1. But Sipeed Tang HEX can be purchased for as little as $73 shipping on Aliexpress,  or 439 RMB ($62) on Taobao for people based in mainland China. It might be tempting to get a low-cost board to get started, but is it worth it? Read on to find out. Sipeed TANG Hex specifications: SoC – Xilinx Zynq-7020 (XC7Z020-1CLG484) dual-core Arm Cortex-A9 processor and FPGA with […]

FontEdit Font Editor Targets Embedded Systems with LED, LCD or e-Paper Displays

Once I had to use a Chinese TTF font in a project were storage was limited, and I managed to reduce the font size with FontForge open-source editor. It works well as long as your system support standard font formats like TrueType or OpenType, but on embedded systems with even fewer resources, it may not be workable due to the size of the font file, and the footprint of the required libraries. Instead, you may have to prepare the font in an image editor and convert those into code with a script and that can be cumbersome. So Dominik Kapusta decided to write a little tool to simplify the process. Meet FontEdit. The program allows you to import fonts, edit glyphs, and potentially add your own custom drawings.  It does have some limitations as it only works with general-purpose fixed-width desktop font and imports font glyphs for characters in the […]

DFI Ryzen Embedded R1606G SBC Review – Part 2: Windows 10 Enterprise LTSC

DFI GHF51 is an AMD Ryzen Embedded R1606G SBC for industrial application that’s about the size of the Raspberry Pi Model B board, and after checking out the hardware in the first of part of the review “DFI GHF51 AMD Ryzen Embedded SBC Review – Part 1: Unboxing and Assembly“, I’ve now had time to play with the board running the pre-installed Windows 10 Enterprise LTSC operating system. DFI GHF51 Hardware Connections Since there aren’t any full-sized USB ports, you’ll need a USB-C hub to get started as you’ll probably want to connect a USB keyboard and mouse for development and testing, as well as a Micro HDMI cable to connect to a TV or display. I tried both MINIX NEO C Plus and Dodocool DC30S USB Type-C hubs, and the former did not work at all, while the latter mostly worked. I also connected an HDMI cable to the […]
