I have a 2011 Raspberry Pi, and after much searching on the internet I cannot seem to find the specs for it. Does anyone have any idea what the main difference between a prototype 2011 Raspberry Pi and a model B Raspberry Pi is?
http://elinux.org/RPi_HardwareHistory lists the revisions of the model B. You can tell which production model of the B you have by counting the number of holes.
No holes - early model B Two holes - later model B Four holes - B+
The specs for any raspberry pi model is on the following website. Just select the correct folder on the right side of the screen https://raspberry-projects.com/pi/pi-hardware/raspberry-pi-pcb-versions
