The cheapest Jasper Lake mini PC so far: JK01 for $140 and up

Cheap Jasper Lake Mini PC

Intel Jasper Lake N-Series Celeron and Pentium processors were formally introduced at the beginning of the year as the successors of the Gemini Lake (Refresh) processors, and we’ve seen several mini PCs and motherboards so far from lesser-known Chinese manufacturers to more established brands like ASUS, GIGABYTE, and ECS. The previous generation Gemini Lake mini PCs would usually sell around $150 to $200, but now with the JK01 barebone computer, we’ve got an inexpensive Intel Celeron N5095 Jasper Lake mini PC selling for about $141 including shipping. CYX JK01 mini PC specifications: SoC – Intel Celeron N5095 quad-core Jasper Lake  processor @ 2.0GHz /  2.9GHz (Turbo) with 4MB cache, 16EU Intel UHD Graphics; 15W TDP System Memory – 2x SO-DIMM slots for up to 16GB DDR4 memory Storage – M.2 2280 socket for NVMe or SATA SSD, 2.5-inch SATA drive bay, MicroSD card socket Video Output – 1x HDMI 2.0 […]

Stellar Data Recovery Professional

Even if you backup your data regularly, data loss can still occur for a variety of reasons be it a power failure, a user mistake, hardware failure, or even viruses or malware like ransomware. But luckily there are professional data recovery software programs that could help save your day, or even your job, such as Stellar Data Recovery Professional for Windows, previously known as Stellar Phoenix Windows Data Recovery Professional, that can recover lost or deleted data from any storage media including HDDs, SSDs, USB drives & optical media (CD or DVD), and it even works with the latest Windows 11 operating system. Stellar Data Recovery Professional supports recovery from NTFS, exFAT and FAT (FAT16/FAT32) formatted drives, even on crashed and unbootable systems, and a new feature is data retrieval from a partially burnt or scratched CD/DVD. The software can restore all types of data including documents, emails, photos, videos, […]

A deep dive into Raspberry Pi Zero 2 W’s power consumption

Raspberry Pi Zero 2 W Power Consumption measurements with Otii Arc

When I completed my review of Raspberry Pi Zero 2 W, I mentioned I would test the power consumption of the board later. It took a while, but I’ve finally come around it using Otii Arc from Qoitech and Otii software to provide some pretty power consumption charts, and even energy consumption. Since the Raspberry Pi Foundation recommends a 5V/2.5A power supply, I’ll first try to get as close as possible as 2.5A, then I’ll go through tricks to reduce idle power consumption to less than 75 mA / 375 mW, and finally check the energy consumption under various CPU core count and frequency. Raspberry Pi Zero 2 W Power consumption under load, with accessories I started with the latest Raspberry Pi OS Lite “Bullseye” image and connected my Raspberry Pi Zero 2 W board to Qoitech Otii Arc tools as shown below. It used to cost around $500, but […]
