KAmod DMX512 - USB-DMX512 Converter with Galvanic Isolation

Zeenko ZK09-BM is a low-noise, ultra-wideband RF amplifier with an operating range up to 10 GHz, powered by a built-in battery. Thanks to its good linearity and noise performance, it is used in measurements, receiver paths and communication systems. Compact and mobile, it will work well both in laboratories and in the field.

Audio preamplifier based on the NE5532 chip. Powered with DC voltage in the range from 9 to 35 V (does not require symmetrical voltage)

Module with electret microphone and LM393 amplifier that will allow you to detect voice, clap, slam doors and other sounds using analog or digital output

Audio module with DAC, amplifier, display and loudspeaker, designed to work with the Raspberry Pi. Pimoroni PIM485

A volume sensor designed to detect loud ambient sounds. The module uses a microphone and LM2904 amplifier. The output value (analog signal) depends on the volume of the detected sound. In order to eliminate interference, the microphone signal is subjected to double filtering. Seeed studio 101020063
