SunFounder’s Raspberry Pi UPS Power Supply is a complete UPS kit for the Raspberry Pi 3/4 Model B/B+ with a PiPower board, a 2,000 mAh battery, and all accessories requires for the assembly. It also works with other Raspberry Pi-sized boards that support 5V DC input such as Banana Pi BPI-M5, Libre Computer ROC-RK3328-CC, and other similar SBCs. Many years ago, I bought a Raspberry Pi battery pack for review hoping that it would also work as a UPS, but it was not perfect as the board would sometime reboot during power failure simulations. Since then, there have been many UPS kits launched to the market, but I didn’t try any so far, so when SunFounder contacted CNX Software to review their “Raspberry Pi UPS Power Supply”, I took the opportunity, and I will report my finding in this review.

The Western Digital hard drive we added to the mini PC also shows up in the list […]
CZUR ET24 Pro book scanner review – Part 1: Specs, unboxing, and first try
CZUR ET24 Pro is a professional book scanner with 320DPI optional resolution (delivering up to 24MP images) that works with Windows, macOS, and Linux via a USB port, or even in standalone mode through an HDMI port that could be used for business presentations. When CZUR contacted me about reviewing a scanner, I was not sure it would be interesting, but then I was intrigued because it looks like a bedside light and I had never used this type of scanner. So I decided to give a go, and here I am with a review sample. It looks like it should be especially useful for people scanning a lot of documents or books as it’s designed for speed and should significantly improve productivity over a traditional scanner with a cover, while hopefully keeping the quality. But we’ll check that in the full review. CZUR ET24 Pro specifications Optical resolution – […]

UniHiker review – A Linux-based STEM education platform with IoT and AI support, Micro:bit edge connector
DFRobot’s UniHiker is a STEM educational platform that was originally launched in China, but now UniHiker is now available worldwide through the DFRobot shop. The company has sent us a UniHiker sample for review, so let’s unpack the kit and learn how to use the UniHiker platform. The main component of the kit is the Linux-powered UniHiker board which features a 2.8-inch resistive touchscreen display and a BBC Micro:bit edge connector, so we can use expansion boards for the Micro:bit board. Let’s start unboxing it together. UniHiker unboxing DFRobot sent us the UniHiker platform by DHL. The package is a familiar-looking DFRobot box in orange color and comes with a plastic box to safely store the UniHiker board and accessories after use. The plastic box contains another plastic box with the board, some 3-pin and 4-pin cables for Gravity ports, and a USB Type-C cable. The UniHiker is like a […]
Using Link.ONE all-in-one LPWAN development kit with ChipStark, Node-Red, InfluxDB, and Grafana
RAKwireless has sent us a review sample of the WisTrio Link.ONE all-in-one LPWAN IoT development kit with support for LTE-M, NB-IoT, and LoRaWAN connectivity and programmable with the Arduino IDE. We’ve tested the kit with its weatherproof WisBlock Unify enclosure using LoRaWAN connectivity and open-source software packages and frameworks such as ChipStark, Node-Red, InfluxDB, and Grafana.

Atezr V35 review – A 35W laser engraver
Karl here. Today let’s look at the Atezr V35 35W diode laser engraver. Atezr is new to the market, at least I am just becoming aware of them, and they asked for a review of one of their machines. This fell in line with the laser power meter project I have been working on, so I accepted, hoping to further along that progress. My goal is to validate the 35W power spec. First, this is 35W optical power….not just the power consumed. You have to be very careful today when shopping for laser engravers. I hate this trend where manufacturers are highlighting total power consumption in marketing materials. This spec is prominently shown in an attempt to trick the consumer into thinking the laser is more powerful than they are. Until starting this review I thought the optical power limit for a single diode laser was 5.5W. I asked Atezr […]
