This kit is intended for someone that already has an Arduino based project in mind or underway that can benefit from a compact and flexible package that provides a small LCD, a user input capability, an SD Card Reader, and access to the Arduino's pins (of course). It could also serve as a platform for a new Arduino user to experiment with the LCD display and SD functionality.
The PCB is designed such that headers can be used to access all of the pins of the Arduino Nano for jumpers. Alternatively the solder points for the header can be used to directly connect leads. The enclosure is designed to allow for either a six pin header through the case or the void for that header can be used for a ribbon cable. There is also a port for a power connector.
The Nano shipped with the kit comes loaded with a program demonstrates the use of the TFT LCD, the SD Card Reader, the three buttons connected to a single analog pin, and a Temperature Sensor that is provided with the kit for purposes of this example (as well as to illustrate general capabilities of the enclosure).

Another Project Example
The first photo shows the wiring inside the case with the second showing it connected to the thermistor inside the 3D printer. At this point in the experiment the DHT-11 was not needed.
The sketch that is running has been modified from the one that comes with the kit and displays, and records, the voltage generated from the voltage divider that includes the thermistor as one leg.
