 Overview
 --------
 
-The Arduino Mega2560 version of Speeduino supports the use of Serial3 for supplemetry IO.The proposed STM32 and Teensy3.5 versions use Serial2 . On a Mega 2560 Serial3 can be found on the board at pins 14 and 15.The connection speed is 115200baud.
-Supplementry IO via Canbus is under development for Teensy and Mega2560 mcu types. The use of canbus will also enable more advanced features to be added in the future.
