Beelink Gemini M is a Thin Mini PC Powered by Intel Celeron J4125 Gemini Lake Refresh SoC

The first Intel Gemini Lake Refresh (GLK-R) processors were announced last November, but we haven’t seen that many devices with the new processors, and so far we only covered some FUJITSU thin clients, as well as ODROID-H2+ and ODYSSEY-X86J4105 SBC’s with the “refreshed” processors. Beelink is about to launch a rather thin mini PC – Beelink Gemini M – powered by a 10W Intel Celeron J4125 Gemini Lake Refresh SoC coupled with 8GB RAM, and offering two independent 4K video outputs. Beelink Gemini M specifications: SoC – Intel Celeron J4125 quad-core Gemini Lake Refresh processor @ 2.00 GHz / 2.7 GHz (Turbo) with Intel UHD Graphics 600; 10W TDP System Memory – 8GB RAM Storage – 64GB eMMC flash, M.2 2242 SATA socket, SD card reader Video Output – 2x HDMI 1.4 ports up to 4K @ 30 Hz Audio – 3.5mm headphone+mic jack, digital audio output via HDMI Connectivity […]

UP Xtreme Lite Whiskey Lake SBC is Made for “Developers on a Budget”

AAEON UP Xtreme Whiskey Kake SBC launched last year for 249 Euros via a crowdfunding campaign, and the single board computer can now be purchased from UP shop from $299 for the Celeron 4305UE version with 4GB RAM, and up to $799 with an Intel Core i7-8665UE quad-core processor and 16GB RAM. But soon, you should be able to purchase a more affordable version as the company just unveiled UP Xtreme Lite board made “for developers on a budget” and “designed to provide developers with a platform that’s flexible, powerful, and great value while not sacrificing performance”. UP Xtreme Lite specifications with the differences against the original UP Xtreme either stricken though (when removed) or highlighted in bold (for new features): SoC (one or the other) Intel Celeron 4305UE dual-core processor @ up to 2.2 GHz with 2MB cache, Intel UHD 610 graphics Intel Core i3-8145UE dual-core 4-thread processor @ […]

HydraNFC Shield v2 Delivers Up to 1600 mW with STMicro ST25R3916 NFC Chipset

When Benjamin Vernoux is not working on open-source firmware & tools for AirSpy R0/R2/mini SDR, he spends his time on other projects such as HydraBus STM32 board with NFC support which we covered back in 2014. The HydraNFC Shield that came with the board was based on Texas Instruments TRF7970A NFC chipset with limited features and not compliant with any RF/NFC standard. Benjamin has now launched HydraNFC Shield v2 powered by STMicro ST25R3916 NFC chipset and equipped with a differential antenna. The new version of the shield still works with the original HydraBus board and allows much more output power (1,600mW vs 200 mW) and supports a wider range of NFC features & standards. HydraNFC Shield v2 features and specifications: NFC Chipset – STMicro ST25R3916 high-performance NFC universal device supporting NFC initiator, NFC target, NFC reader and NFC card emulation modes Antenna – Differential antenna with power up to 1600mW […]

Industrial-Grade Optical Rain Gauge Beams Infrared Light to Measure Rainfall

I remember when I was a kid, we had rain gauge to measure the amount of rainfall in the garden, so after heavy rains, I liked to have a look to find out how much rain actually fell. Those collected water in a tube, and we could read the millimeter value right on the tube. But now with the Internet of Things, we can have smarter solutions including tipping-bucket rain gauges that collect water and usually report the data via an RS-232 port. But I’ve just found out there’s another method to measure rainfall with an industrial-grade optical rain gauge I just found on Seeed Studio for $99.00. It’s a sphere about the size of half a tennis ball that beams infrared light instead of collecting water and somehow managed to accurately report the amount of rainfall. RG-15 optional rain gauge specifications: Nominal Accuracy – ±10% Host Interfaces J1 Terminal […]
