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 […]

PicoVoice offline Voice AI engine gets free tier for up to 3 users

PicoVoice Console Custom Wake Word

PicoVoice offline Voice AI engine has now a free tier that allows people to create custom wake words and voice commands easily for up to three users on any hardware including Raspberry Pi and Arduino boards. I first learned about PicoVoice about a year ago when the offline voice AI engine was showcased on a Raspberry Pi fitted with ReSpeaker 4-mic array to showcase the company’s Porcupine custom wake word engine, and Rhino Speech-to-Intent engine. The demo would support 9 wake words with Alexa, Bumblebee, Computer, Hey Google, Hey Siri, Jarvis, Picovoice, Porcupine, and Terminator. More importantly, the solution allows you to easily create your own custom words in minutes from a web interface by simply typing the selected wake word, with no need for hundreds of voice samples or waiting weeks to get it done. So I tried “Hey You” first, but I was told it was too short, […]

Raspberry Pi 4 PLC Industrial controller targets IIoT applications

Raspberry Pi 4 PLC

I’ve just noticed Boot&Work Corp was now offering an “Industrial Shields” branded PLC industrial computer powered by Raspberry Pi 4 SBC. We previously covered the company in 2017 at a time when they provided Arduino-based PLC modules optionally controlled with 10.1-inch panel PCs based on ARM Linux SBCs such as Raspberry Pi or Banana Pi. The “Raspberry Pi PLC Industrial Controller” is offered with either optoisolated outputs or relay outputs, and optional GPRS connectivity. The Linux PLC is equipped with up to 36 digital inputs, 16 analog inputs, 8 analog outputs, and 6 interrupts, as well as communication interfaces such as CAN bus, up to 2x Ethernet ports, dual RS-485, WiFi, and Bluetooth. Raspberry Pi PLC Industrial Controller basic specifications: Single board computer – Raspberry Pi 4 SBC with 2GB to 8GB RAM, WiFi 5, and Bluetooth 5.0 connectivity Storage – 8GB MicroSD card Video Output – 2x Micro HDMI […]

10.1-inch Raspberry Pi All-in-One touchscreen display review – Part 1: Unboxing and installation

Raspberry Pi OS All-in-One Touchscreen Display

I’ve just received a 10.1-inch touchscreen display designed for Raspberry Pi model B boards with 1200×800 resolution from the EVICIV store on Amazon that also offers models with 1366×378 and 1920×1200 resolutions, and allows users to create an All-in-One computer based on the popular SBC. The product can also be used as a standalone display connected to an HDMI or USB-C (via DisplayPort Alt mode) source, so it could be interesting for all sorts of projects and not only ones relying on Raspberry Pi boards. In the first part of the review, I’ll check out the hardware, install a Raspberry Pi 4, and boot it to check out whether it works, before going into more details in the second part of the review. RPI All-in-One Touchscreen Display Unboxing The package lists some of the specs and highlights features of the device with a built-in stereo speaker, support for older and […]
