Assembled Project

2.4"Colour Touchscreen Display

Feather M4 Express Microcontroller

Ultimate GPS FeatherWing

FeatherWing Doubler Prototyping Bd.

LiPo Battery & JST Cable

Arduino C/C++ Code

Description:

A handy device that can track where you've been.

Parts:

 - Adafruit Feather M4 Express microcontroller

 - Adafruit 2.4" 320x240 TFT LCD touchscreen FeatherWing peripheral

 - Adafruit Ultimate GPS FeatherWing peripheral

 - Adafruit FeatherWing doubler prototyping board for attaching peripherals

 - LiPo 3.7v battery and 2-pin JST cable

Features:

 - Time & date (provided by the GPS, accurate to within one second), coin cell battery backup

 - GPS coordinates & stats

 - Plots your starting and current location

 - LiPo battery power & 2-pin JST cable

 - Arduino C/C++ code can be changed via the miniUSB connector

 - Display is timed out and backlight is disabled (to save battery power) after a short time interval on every screen (except GPS Plot)

Power Input:

 - LiPo battery (3.7v) or miniUSB: 5vDC

Use Case:

Press Start GPS Plot when you leave your vehicle, then pocket the device.

When you return to the parking lot you have a general idea of where your vehicle was parked based on the plotted path you walked.

Possible Improvements:

 - Push the GPS plots into an array so they can be restored anytime until Clear GPS Log is chosen

 - Push the plots onto the display's microSD card for permanent storage

 - Build a small 3D-printed project case
