The Arduino OBD-II logger kit #3 based on an Arduino MEGA2560 will soon get upgraded. The LCD1602 in the previous kit will be replaced by a 2.8″ TFT LCD shield. The new kit also includes a new I/O breakout shield for MEGA2560 which provides four 4-pin UART ports and one 4-pin I2C port on the side of the board, so that it is easier to connect the OBD-II UART adapter model B to Arduino.
To match up the upgrade in hardware, the software is also being improved. With the new MEGA logger sketch, the new kit can be used to display more information from the car in a more fancy way.
