RASPBERRY PI 1 MODEL B+
The Model B+ is the final revision of the original Raspberry Pi. It replaced the
Model
B
in July 2014 and was superseded by the
Raspberry Pi 2 Model B
in February
2015. Compared to the Model B it has:
•
More GPIO.
The GPIO header has grown to 40 pins, while retaining the same
pinout for the first 26 pins as the Model A and B.
•
More USB.
We now have 4 USB 2.0 ports, compared to 2 on the Model B, and
better hotplug and overcurrent behaviour.
•
Micro SD.
The old friction-fit SD card socket has been replaced with a much
nicer push-push micro SD version.
•
Lower power consumption.
By replacing linear regulators with switching
ones we’ve reduced power consumption by between 0.5W and 1W.
•
Better audio.
The audio circuit incorporates a dedicated low-noise power
supply.
•
Neater form factor.
We’ve aligned the USB connectors with the board edge,
moved composite video onto the 3.5mm jack, and added four squarely-
placed mounting holes.
