Neem Tech Spectrum Analyzer Board with 3.5mm Audio Jack

Description

Product Overview

The Neem Tech Spectrum Analyzer Board is a compact, high‑precision device designed to turn audio signals into visual frequency data. Built in California, it features a 3.5mm stereo audio jack for direct connection to phones, laptops, or any line‑level source. The board includes pre‑soldered 0.1″ pitch pins that fit standard breadboards, making it ideal for rapid prototyping with popular microcontrollers like Raspberry Pi, Arduino, and BeagleBone. Its lightweight aluminum‑clad PCB ensures durability while keeping the package dimensions to just 3.86 x 2.64 x 0.75 inches.

Usage

Designed for makers, educators, and audio engineers, this analyzer fits seamlessly into labs, classrooms, and hobby workshops. Connect a music player, instrument, or test signal to the 3.5mm jack and let the microcontroller process the seven peak‑detected frequency bands. Use it to create visual light shows synced to music, build educational demos of Fourier analysis, or troubleshoot audio equipment. Its low power draw and small footprint allow portable field use as well.
