This slot provides the user with the option of storing collected data onto a microSD card. The connector gives 5 basic user options: The joystick included on the shield provides a basic user interface for controlling screen displays or selecting CAN scan settings. The connection is designed for 5V LCDs, so don't accidentally plug in a 3.3V option! The pin order is 5V, GND, and RX/D6 when looking at the shield straight on. The LCD footprint on the shield is compatible with a male 3-pin JST connector and can interface with any of our serial LCD screens. The GND jumper allows the user to modify the GPS connector for units that do not have a GND connection on pin 5 of the connector. The board is designed to interface with either the EM-506 GPS Receiver, or the GP-735 GPS Receiver. The GPS connector on-board is a 6-pin, JST SH compatible connector.
This allows you to interface to OBD-II ports with a DB9 to OBD-II cable.
The primary hardware feature on this shield is the DB9 connector.
