How Much Power does Raspberry Pi 3A+ plus Use?

When 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 is powered using a bench power supply at 5.2V (supply current limit = 3 Amps) wired, via my eMeter’s calibrated 20 Amp shunt, to the µUSB power input on the Pi. Current and voltage are measured using the eMeter (with clamp meter to confirm) and calibrated shunt whilst performing four different activities […more…]
