6X LM393 Adjustable Comparator Module Development Board Analog Output

Description

Product Overview

The Kokiya 6X LM393 Adjustable Comparator Module is engineered for engineers and hobbyists who demand precise analog signal processing in a compact footprint. Built around the classic LM393 dual comparator, the board offers a fully adjustable output threshold that can be fine‑tuned to match a wide range of sensor voltages. Operating from 3.3 V to 5 V, the module is compatible with most microcontroller platforms, including Arduino, Raspberry Pi, and STM32 families. The XH2.54 pin header provides a reliable 2.54 mm pitch connection, simplifying integration into breadboards and custom PCBs. With a dedicated analog output pin, users can directly monitor voltage changes without additional conversion circuitry, reducing system complexity and cost.

Key specifications include a digital output form that can be configured for open‑collector or push‑pull operation, a sensitivity adjustment range of 0 mV to 2 V, and a robust PCB layout that minimizes noise and cross‑talk. The module’s compact dimensions (45 mm × 30 mm) make it suitable for space‑constrained applications, while the high‑quality solder mask ensures long‑term durability under industrial conditions.

Usage

This comparator module excels in environments where accurate voltage threshold detection is critical. It is ideal for interfacing with temperature sensors, light detectors, pressure transducers, and other analog devices that require a clean digital signal when a set point is reached. In industrial electrical projects, the module can be used for over‑voltage protection, motor speed monitoring, and safety interlocks, providing reliable performance even in noisy settings.

For prototype development, the adjustable sensitivity allows rapid iteration without the need for additional hardware. Engineers can experiment with different threshold levels on the fly, accelerating the design‑validation cycle. The module also integrates seamlessly into educational kits, giving students hands‑on experience with analog‑to‑digital conversion and signal conditioning techniques.

FAQ

What voltage range can the comparator detect?

The module can detect voltage thresholds from 0 V up to 2 V, adjustable in fine increments to suit a variety of sensor outputs.

Is the module compatible with 5 V logic levels?

Yes, the board operates safely between 3.3 V and 5 V, making it suitable for both 3.3 V and 5 V logic environments.

Can I use the module with a Raspberry Pi?

Absolutely. The XH2.54 header aligns with the Raspberry Pi’s GPIO pins, and the analog output can be read using an external ADC if needed.

How do I adjust the sensitivity?

Sensitivity is adjusted via a small potentiometer on the board; turning the knob changes the reference voltage that determines the comparator’s switching point.
