+====== Description ======
+Thanks to many enthusiastic users of Rocrail around the world, there is always something new.\\
+Here is an idea and design of Gerhard Bertelsmann which enables a new approach.\\
+Using a Raspberry Pi B, an interface was developed to create a connection with CBUS and RocNet on one board.\\
+Via Raspberry Pi, it is possible to connect CBUS (CAN) and RocNet via Ethernet.\\
+And of course, Rocrail server can run on this Raspberry Pi itself, making a safer use of Wifi connected Rocview client.\\
+Basically, this unit combines a CAN-GC1(e) and a GCA_PI01 in one unit.\\
+Except of course the 12 Volt supply as used with CAN-GC1(e).\\
+That supply should be created externally, but Pi01Can has the connections available to transport that supply to the CBUS network.\\
+For combination with Märklin Trackbox and CS2 please refer to [[https://wiki.rocrail.net/doku.php?id=mbus:mbus-en|MBUS]].\\
+====== Technical ======
+^Isolated means that there is an opto coupler between the Raspberry Pi and the CAN bus.^
+The design is able to isolate the Can Network from the Raspberry Pi, so the connected Ethernet will be isolated from Can as well.\\
+Two jumper are on board to enable or disable the isolation.\\
+When isolation is disabled one power supply of 12V, connected to the screw-terminals will be sufficient to\\
+have 12 Volt to the D-connector for CBUS, and also a 5V is created for the Raspberry Pi.\\
+The DC/DC converter U1 can be omitted in this case.\\
+When isolated is enabled, the DC/DC converter is needed to supply the isolated side of IC4.\\
+Volt is still needed for the CBUS, and the Raspberry Pi needs 5 Volt supply via RocNet RJ12 socket or via USB .\\
+IC3 as on this prototype board, is no longer needed, and will be deleted in the final board design.\\
+The 5V regulator VR1 is a very efficient switching type regulator, which will be able to supply 1 Amp continuously,\\
+making it possible to run the Raspberry Pi with it.\\
+IC2 is the CAN converter, communicating with the Raspberry Pi computer via standard SPI.\\
+Jumper Jp1 is needed if this unit is at one of the ends of the CAN-line.\\
