Description
Arduino Leonardo based board with expansion header based on Aduino UNO. CAN interface using either MCP2515 or MCP 2518 CAN controllers and bus tranceivers interfaced via DB9M or screw terminal. DC jack for optional power if OBD cable not used. Mini SD card slot for storing logs,. Serial and I2C groove connectors for easy connections to displays or other modules.  Arduino Uno expansion headers and powerfull 1A voltage regulators for 5.0v and 3.3v voltage rails.  Wth optional expansion board(s) you can add other hardware bus interfaces i.e L or K.
