TAIHE Gemini is a 15.6″ Full HD or 4K Portable Display (Crowdfunding)

TAIHE Gemini 4K Portable Touchscreen Display

Portable displays have been available for a while, but they used to be fairly heavy, as for example, Gechic On-Lap Monitor 2501M 15.6″ portable monitor weighted 1.3 kg with cover. However in recent times, we’ve seen several such products – LAPSCREEN and DUO Add-on Display – launched with lighter designs, and the advance as USB type-C and power delivery make those even more attractive since a single cable can be used to transfer video, and power both the display and the host device. TAIHE Gemini is yet another option, but at 15.6″ is larger than the two aforementioned products, it is equipped with its own battery and kickstand, and comes in two variants with either 1920×1080 Full HD or 3840×2160 (4K UHD) resolution. TAIHE Gemini FHD & UHD portable displays specifications: Display Gemini FHD – 15.6″ 10-point touchscreen IPS display with 1920×1080 resolution, 15ms response time, 180° kickstand Gemini UHD – 15.6″ IPS display with 3840×2160 resolution, 14ms response time, …

Orange Pi 3 Allwinner H6 SBC Comes with GbE, USB 3.0, mPCIe

Allwinner H6 SBC

When Shenzhen Xunlong Software launched their first Allwinner H6 development board, Orange Pi One Plus, many were disappointed as the board did not make use of some of the key features of H6 processor like USB 3.0 or PCIe, and RAM was limited to 1GB. A couple of weeks later, the company introduced Orange Pi Lite2 board with 802.11ac WiFi, a USB 3.0 port, HDMI 2.0a output, but no Gigabit Ethernet, nor PCIe interface, and again only 1 GB LPDDR3 memory. The good news is we now get a full-featured Allwinner H6 SBC thanks to Orange Pi 3 equipped with up to 2GB RAM, an optional 8GB eMMC flash, Gigabit Ethernet, 802.11ac WiFi 5, four USB 3.0 ports, HDMI 2.0a, a mPCIe slot, and more. There are four variants of the Orange Pi 3 board with either 1 or 2 GB RAM, with or without eMMC flash that share the following specifications: SoC – Allwinner H6 V200 quad-core Cortex A53 …

ATORCH USB PD Power Meter Comes with USB type-C, type-B, and type-A Ports

ATORCH J7-c

Most smartphones are charged over a USB port, and many single board computers are powered by a micro USB or USB type-C port, and USB power meters such as USB Charger Doctor can be useful to evaluate phone chargers, as well as measure power consumption of SBCs. With the launch of the USB type-C connector and features such as USB PD (Power Delivery), old USB power meters are not adapted to the new standard since the connector and most importantly voltages are different, so we need USB PD compatible meters like Satechi USB Type-C power meter. Today, I decided to look for more options on Aliexpress, and you’ll find many USB-C power meters with the cheapest models going for under $5 shipped. However,  ATORCH J7-c model caught my attention since it supports both USB type-C, micro USB type-B, and USB type-A power sources, so you can keep using the same meter for all your USB testing needs. ATORCH J7-c USB-PD …

FDK Unveils Tiny SMD Solid-State Batteries

FDK SMD Battery

Coin-cell batteries are often used in wearables or system with a real-time clock (RTC). They do the job just fine, but over many years they may start to leak, and some applications may benefit from even smaller batteries. Leaking can be solved by going with solid-state batteries, and we’ve seen in the past TDK launch CeraCharge solid-state batteries packaged into an ultra small SMD form factor. TDK CeraCharge batteries now have at least one competitor with FDK introducing their own SMD solid-state batteries using a high electrochemical potential cathode material “lithium cobalt pyrophosphate” (Li2CoP2O7). Key features: Energy Density – 26mWh/cm3 Voltage / Capacity – High voltage 3.0V, “high capacity” 140μAh Dimensions – SMD type; 4.0mm x 2.0mm x 2.0mm Temperature range – -20 – +105℃ Safety – High safety and environmental adaptability, use inflammable materials, use stable oxide sintered ceramics (sulfide free) The small size, high capacity, and wide temperature range of the batteries make them suitable for various IoT …
