Description

IMU Array Sensor board

An IMU array project aims to replace geophones by synchronizing multiple IMUs for noise averaging and data processing. The sensor board utilizes an FPGA for data aggregation and a custom layout to minimize mechanical stress, while the processing board features a PicoW module for WiFi communication and a GPS module for time alignment. The project prioritizes size and flexibility, with a focus on minimizing analog components and utilizing readily available hardware.
