How much power does the Pi4B use? Power Measurements

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. Procedure 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 […more…]

Raspberry Pi 4 launches with BCM2711 quad-core Cortex-A72 64-bit SoC running at 1.5GHz with dual 4K display capability

Raspberry Pi 4B launches today. It’s a fresh new generation of Pi with brand new silicon – the Broadcom BCM2711, quad-core Cortex-A72 (ARM v8) 64-bit SoC running at 1.5GHz. The new VC6 GPU is able to drive dual 4Kp30 displays and can handle H.265 decode at 4Kp60. It has true Gigabit ethernet (independent of USB), USB 3.0 and dual 4K HDMI outputs (micro). There’s also 2.4 GHz and 5.0 GHz 802.11b/g/n/ac wireless and a choice of 1GB, 2GB or 4GB LPDDR4 memory (depending on which model you select). Pi4B is the same form factor as […more…]
