Each time a new Pi comes out, I usually publish some power consumption figures, mainly for those people who want to estimate battery durations. So my tests are quite simple.
With just an HDMI screen and a USB keyboard/mouse dongle connected, the Pi current usage was measured using my non-invasive UNI-T clamp meter and a slightly mutilated Anker USB-C lead (to be able to clamp round just the red +ve wire I have to open it up) connected to the Tronsmart 3A power supply I’ve been happily using with my Pi4B. In the past I’ve used my e-Meter AND this clamp meter with a bench PSU and all the readings have agreed closely with each other. This time, rather than destroy TWO USB-C cables I went with just the clamp meter.
Each Friday is PiDay here at Adafruit! Be sure to check out our posts, tutorials and new Raspberry Pi related products. Adafruit has the largest and best selection of Raspberry Pi accessories and all the code & tutorials to get you up and running in no time!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
