Raspberry Pi Model B+
After successful years of availability of the Raspberry Pi models A and B, the revised “Model B+” of the Raspberry Pi was released.
This computer board was not intended as a direct successor to the “RPi 2”, but rather as an improved and final version of the previous B model, adapted to the wishes of the community.
The Raspberry Pi B+ board has the following features:
– more GPIO connections: The number of pins has now increased to 40, the pin assignment of the first 26 is identical to that of model B.
– more USB ports: Compared to model B, B+ has 4 ports with better “hot-plug” and overcurrent behaviour.
– Micro SD slot: The new Micro SD slot replaces the previous SD card holder, which saves space and is safe because the memory card no longer protrudes.
– Reduced energy consumption: By using new components for voltage regulation, energy consumption has been reduced by approx. 0.5 to 1 watt.
– Better audio: Special new components have also been used here to reduce interference.
– new form factor: All inputs/outputs have been rearranged on the circuit board and 4 new mounting holes have been added for secure installation in the housing.
What remains…
The BCM2835 processor and the 512 MB RAM remain the same as on the B model, but the:
– 4-pin 3.5mm stereo audio connection with composite video output,
– HDMI video output,
– RJ45 network cable connection,
– Micro USB socket for the power supply,
– and the connection strips for the Pi camera and a display.
… the most important thing for most users, however, is the price of the new Raspberry Pi Model B+ board …
This is again within an absolutely affordable range and at the same level as the previous model.
