The PCB, with a circular shape, will sit at the bottom of the system and will include:

• an ESP32-S3,

• a MOSFET transistor (IRLZ44N ?) to cut the servo’s power supply (minimizing disturbances during measurements),

• a NEOM9 GPS to timestamp and precisely geolocate the readings,

• connectors for the sensor, servo, and a 2.8-inch touchscreen with a 9344 controller.

🙏 A big thank you to PCBWay, who agreed to support this project and help along the way!
