“This project describes how to build a GPS data logger at a lower cost.
I practice aeromodelling and I like to know the speed and altitude of my planes. unfortunately, commercial data logger gps are very expensive.
So I decided to make a data logger gps based on arduino for a cost less than 50 €.
My first prototype is based on aruino uno R3 with a sainsmart ST7735 screen with integrated SD card and a NEO 6M V2 gps module.
In the second project I would use an arduino nano with an oled ssd1306 screen, the same gps and a micro SD card. the weight with case should weigh around 40 grams and can easily be integrated into a medium-sized aircraft (size L 50 mm X l 30mm X H 22mm).”
