Square Trimpot
This breadboard-friendly 10k Omega square trimpot features a built-in knob for easy manual adjustment—ideal for prototyping volume controls, sensor thresholds, or LCD screen contrast.
Linear Voltage Regulator
A foundational electronic power management component designed to maintain a stable, fixed output DC voltage despite fluctuations in input voltage or load current. Operating with low output noise and simple external circuit requirements, it is widely used for step-down regulation in sensitive analog and digital microcontrollers.
Tectonic 32.2mm dia 1W nom Full Range Audio Exciter
A compact 32.2 mm diameter audio transducer engineered to transform solid resonant surfaces into haptic speakers. Operating at an 8 Ohm impedance across 500 Hz to 20 kHz, it applies bending-wave physics to generate wide-dispersion full-range acoustic output without requiring a traditional cone enclosure.
PAM8403 Digital Power Amplifier Board
A miniature Class-D dual-channel audio amplifier module delivering efficient 2x3W stereo amplification directly to 4 Ohm or 8 Ohm speakers. Operating on a low 2.5V to 5V DC supply, it features over 90% power efficiency, low noise distortion, and minimal external component count for portable embedded audio projects.
