Map as you go and track your path with this project from taste_the_code on Instructables:
Today, I’m particularly excited because I’ve been working on a nifty little gadget using a GPS module – a device tailor-made for recording natural trails in the wild. As you may know, I love both tech and the great outdoors, so combining the two is a real treat.
The core of my homemade GPS mapper is an ESP32 microcontroller to which I’ve attached a RYS352A GNSS module from Reyax via TX and RX connections on a separate hardware serial port. It’s powered by a supply of 3.3 volts and incorporates a data logging shield that houses a microSD card, utilizing the SPI interface for data storage. For user interaction, I installed an LED that visually indicates when the device is recording a GPS track and added a push button to initiate or cease recording. The track is neatly saved onto the microSD card in separate files for each recording session, allowing for easy organization and retrieval of the data once back from the field.
Make a GPS logger to map your dog’s playtime at the park or hike in the woods! This intermediate FLORA microcontroller circuit is a great first GPS project! Use conductive thread to stitch up the sewable GPS and FLORA so there’s no soldering required.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
