$150 InkPalm Plus eReader features RK3566 SoC, 5.84-inch display

Xiaomi Inkpalm Plus

Xiaomi Moaan InkPalm Plus is a 5.84-inch eReader powered by the same Rockchip RK3566 processor found in Pine64 PineNote 10.3-inch Linux eReader, and currently selling for 999 CNY, or about $150 US, on JD.com after a 100 CNY discount. The device looks more like a smartphone than an eReader with its relatively small display, but there must be demand for this type of hardware since it succeeds the earlier InkPlam 5 eReader with Allwinner B300 quad-core Cortex-A7 SoC, plus an even smaller 5.2-inch display. Inkpalm Plus specifications: SoC – Rockchip RK3566 quad-core A55 processor @ 1.8 GHz with Arm Mali-G52 EE GPU, 0.8 TOPS NPU (AI accelerator) System Memory – 2GB RAM Storage – 64GB eMMC flash Display – 5.84-inch E Ink display with 1440×720 resolution (276 PPI), front light with 24 levels and adjustable color adjustment, 5-point capacitive touch Audio – Mono microphone Connectivity – Dual-band 802.11b/g/n/ac WiFi 5, […]

E Ink Gallery 3 color ePaper offers faster refresh rate, higher resolution

E Ink Gallery 3 color epaper display

This is confusing. E Ink just announced the Kaleido 3 color e-paper at the beginning of the month, and now comes up with E Ink Gallery 3 color e-paper. Before we try to look into the differences, let’s see what E Ink says about the new Gallery 3 color ePaper technology. Designed for the eReader and eNote markets, E Ink Gallery 3 is based on the E Ink ACeP  (Advanced Color ePaper) with a full-color gamut achieved through a four-particle ink system: cyan, magenta, yellow and white, which allows a full-color gamut at each pixel. The earlier E Ink Gallery has a black and white update time of two seconds, and color updates of ten seconds. The new Gallery 3 ePaper technology slashes those times to 350ms for black and white and as low as 500 ms in fast color mode. The standard and best color modes have refresh rates […]

E Ink Kaleido 3 color e-paper display increases color saturation by 30 percent, reduces blue light reflections

E-Ink Kaleido 3

E Ink’s latest Kaleido 3 color ePaper display increases color saturation by 30 percent compared to the earlier Kaleido Plus color e-paper display, integrates E Ink ComfortGaze new front light technology engineered to reduce the amount of blue light reflected off the surface of the display, in order to provide further comfort while reading. The new modules based on Kaleido 3 will be offered in various panel sizes including 7.8-inch, 10.3-inch, and 13.3-inch, support up to 16 levels of grayscale and 4096 colors, and target eReaders and eNote devices. E Ink explains that Kaleido 3 relies on the company’s Print Color ePaper technology, “where a color filter array (CFA) is used in conjunction with E Ink’s Carta black and white ink film, creating a full-color device for a more fully realized eBook shopping and reading experience”.  As I understand it that part has not changed, and it’s just the same […]

E-Ink Digital Paper Tablet is about the size of an A4 or US Letter paper

E-Ink Digital Paper Displays

While there’s now a bunch of devices with an e-paper display, be it tablets or eReaders, it’s harder to find a model that is about the size of A4 (297 x 210mm) or US letter (279 x 216mm) papers. E-Ink Digitial Paper Tablet solves this issue with an NXP i.MX 8M Mini-powered Android 9 tablet offering a 13.3-inch display (301.1 x 222.8mm), as well as a smaller 10.1-inch display, for business applications. Both digital paper tablets feature E-Ink Carta 1250 screen technology with a higher contrast ratio and faster refresh rate, come with a digital pen supported by Wacom’s battery-free EMR technology, and are said to last about three weeks per charge for light usage. E-ink digital paper tablet specifications: SoC –  NXP i.MX 8M mini quad-core Cortex-A53 processor @ up to 1.8GHz Storage – 32 GB eMMC flash including 24GB for user data, or enough for about 10,000 typical […]

FOSDEM 2022 schedule with embedded Linux, IoT, automotive… sessions

FOSDEM 2022

While typically taking place in Brussels, Belgium, FOSDEM 2022 will take place online just like FOSDEM 2021 due to COVID-19 restrictions. The good news is that it means anybody can attend it live from anywhere in the world, and makes it more like “FOSDIM”, replacing European with International, in “Free and Open Source Developers’ European Meeting”. FOSDEM 2022 will take place on February 5-6 with 637 speakers, 718 events, and 103 tracks. I’ve made my own little virtual schedule below mostly with sessions from the Embedded, Mobile and Automotive devroom, but also other devrooms including “Computer Aided Modeling and Design”, “FOSS on Mobile Devices”, “Libre-Open VLSI and FPGA”, and others.   Saturday, February 5, 2022 12:30 – 13:00 – Five mysteries in Embedded Linux by Josef Holzmayr Once you start out in embedded Linux, there is a lot to do. Some things are obvious, some less so. First and foremost, […]
