Geophone - SM-24, with Insulating Disc Shipping:2-4 Weeks LAP mode here needs only

LAP mode here needs only one PWM signal instead of two anti-phased signals

Differential drive

The ZED-F9T GNSS Timing Breakout could be the perfect solution

The VL53L1X is effectively a tiny

these packet radios are simpler than WiFi or BLE

Geophone - SM-24, with Insulating Disc Shipping:2-4 Weeks LAP mode here needs onlyNeed to put your finger on the pulse of the Earth? Did I just blow your mind? A geophone works by translating ground movement into voltage, which can easily be read by a microcontroller. The SM 24 geophone element is designed to offer the highest performance in seismic exploration based upon field proven I O Sensor technology. Low distortion, combined with excellent specifications, provide high fidelity data. Basically, it's a super low frequency
