  Intro

  This is a GPS tracker which displays all the positional data on the OLED display. A button helps the user to interact with a UI on the OLED.

  Hey, what's up, guys? Akarsh here from CETech.

  The code offers a menu driven program using the onboard button, which when pressed for a short interval, cycles through menus of the GPS data like Latitude, Longitude, Altitude, Speed etc.

  You can upload this data using the esp32 on the internet using wifi or Bluetooth to a smartphone.

  So, in short, this project has an ESP32 which can give WiFi/Bluetooth functionality, OLED display and GPS module. Possibilities with the code are endless. I have also added a prototyping area where you can add sensors or other components to the ESP32 which is also accessible.

  Parts

  Firstly as the main part, I used an ESP32 module from DFRobot. Attached it on the PCB using some male and female headers. I used an OLED display.

  For the GPS purpose, I used a Reyax GPS module. I highly suggest this module as it is very easy to use over UART bus.

  You can find the parts below:

  1) ESP32 FireBeetle Module: https://www.dfrobot.com/product-1590.html

  2) Reyax RYLR896 LoRa module: https://www.ebay.com/itm/REYAX-RY8253F-10Hz-GPS-Gl...

  3) My PCB design: I have included the Gerber file below.

  For the last two parts if you have difficulty in finding them out you can message/email me and either I can help you find it in your area or I can ship them to you if you wish.
