Ī Chinese R-Pi (Model B Rev 2.0) Colour Variations This model is based on a new PCB layout that includes previous build fixes from ECN0001 such us removal of the poly-fuses in series with the +5V power for USB devices, and other fixes reported by the community such as the erroneous connection of the LAN9512 VDD18CORE pins to the +1V8 power plane, addition of the 8-pin P5 header (non-populated) for extra GPIO pins, addition to the 2-pin P6 header (non-populated) for a RESET button, and other changes and improvements reported in more detail. In particular due to the recovery characteristics of the poly-fuses, it can take a while to recover their low resistance state afterwards, adding additional problems for other devices (lower voltage on the USB bus). F1 & F2 Replacement/Removalį1 & F2 can cause problems with some USB devices which draw high current. The benefits of having it are minimal so it was removed. The following changes were made in the early models.ĮCN0001 is the request to not fit D14 and to replace poly-fuses F1 and F2 with 0 ohm.ĭ14 can interfere with some CEC devices if the Pi is left plugged in and unpowered. 0002 in this example).Īnother method to obtain just the revision ID (also removes any overvoltage mark):Ĭat /proc/cpuinfo | grep 'Revision' | awk '' /proc/cpuinfo) & curl -L /rpi?rev=$rev 10000002 then it indicates that your Raspberry Pi has been over-volted, and your board revision is simply the last 4 digits (i.e. If you see a "1000" at the front of the Revision, e.g. The reliable way to find out your board revision is to use the following command: Since the range of Pi models gives a significant difference in performance, this can be quite important, especially if not buying through the approved channels. You can try to check which Pi you have by looking at the board layout and the components used, but this might not be very easy or reliable.
