Questions tagged [pi-b+]

This tag is specifically for the enhanced Pi model B+ that has 4 USB 2.0 ports and a 40-pin GPIO header compared to the earlier model B which only had two and a 26-pin header, and always has 512MBytes of memory. It has a single core Broadcom BCM-2385 processor in which it differs from the quad-core unit of the Pi 2 Model B. It has, like other B devices, the 10/100 BaseT Ethernet connectivity which Model A devices lack.
