 +The I/O unit with tremendous options.\\
 +===== Features =====
 +This unit is based on WIO_01, but with even more options for I/O.\\
 +  * Rocrail communication via Wifi or CAN
 +  * 32 x digital I/O (usable for a large range of GCA extension boards)
 +  * 4 x servo (on board supply)
 +  * 2 x RFID input
 +  * switching 5 V power regulator for more economical energy consumption
 +  * I2C connection for display
 +  * connection for GCA214 Railcom sensor
 +  * output for fastled
 +  * output for stepmotor driver
 +  * RocNetNode I2C connector
 +\\
 +**This board is still under development.**

 +===== Firmware info =====
 +Since this board is using same firmware as other WIO related units, the complete concept\\
 +is explained in one page.
 +[[  https://wiki.rocrail.net/doku.php?id=arduino:wio-en  ]]
 +===== Description =====
 +Based on experiences with Lolin D32, used in WIO_Control unit, it provided much\\
 +more I/O possibilities, with a higher speed.\\
 +And it was also possible to put all the extra features in the same WIO sketch.\\
 +So in rather short time this WIO_02 was developed.\\
 +One big advantage was the internal built in CAN interface inside the Lolin D32.\\
 +That enables to introduce the RCAN and MBUS interfaces with little external hardware,\\
 +Also RocNet based on I2C is again available on this board, including\\
 +the standard buffer to make this RocNet compatible with all GCA_PIxx boards.\\
 +But due to the fact that there has been several discussions, why this not really cheap buffer\\
 +is needed when only very short connections are made, this boards also features the option to\\
 +discard this buffer and use two jumper to switch to standard I2C.\\
 +I personally prefer the buffered situation at all times, based on a long time professional use\\
 +of (buffered) I2C for agricultural climate control systems.\\
 +But now the user can make his own decisions in that matter.\\
