ESP32 come in so many different modules and packages it’s difficult to keep track! A popular module is the ESP32CAM which features a camera attached to an ESP32. This PCB from Stuarts Projects receives an ESP32CAM, a LoRa radio and a GPS to create a lightweight and budget friendly GPS Tracker with image capture capabilities.
Adding a Hope RFM9X LoRa module and a choice of GPS modules Stuart has provided an Arduino sketch which when combined with the ESP32CAM creates a platform that takes pictures periodically and stores them on an SD card. The GPS co-ordinates are read from the GPS module and sent over LoRa making this perfect for High Altitude Balloon (HAB) projects.
On the product page and in the documentation there are links to code examples as well as descriptions of different hardware approaches. The PCB has different options for different power supplies and antenna connections as well as different GPS module choices. If you are looking to build tracking systems for HAB projects Stuart has a range of products, libraries and research on different approaches and we recommend you explore his shop, repositories and links.
