Following on from an earlier post about the B+, I’m now the proud owner of an A+.
As I’d previously produced a simple table showing relative current consumption, I feel obliged to update this by including the new Pi.
The new A+ is smaller and cheaper than the A/B/B+ models, making it an ideal candidate for many projects including media players and headless, wifi monitors.
Each model of the RaspberryPi has been connected to a test circuit like this:-
The supply current was measured on an inexpensive (i.e. cheap) digital multimeter.
Measurements were taken for a number of conditions, starting with nothing connected, not even an sd card.
The new A+ is a valuable addition to the range.
It is now a better choice than the model A for my bird box projects because the foot-print is smaller (especially allowing for SD card insertion/removal) and the battery should last a few hours longer.
For robotics there is the benefit of reduced weight, in addition to size and power consumption.
