Description
Product Overview
The Digital 38kHz IR Receiver & Transmitter Module Kit from DKARDU delivers a versatile, plug‑and‑play solution for developers, hobbyists, and educators seeking reliable infrared communication components. Each kit contains five high‑sensitivity 38kHz IR receiver modules and five matching transmitter modules, each paired with a Dupont cable for straightforward breadboard integration. The modules operate at a standard 38kHz carrier frequency, ensuring compatibility with a wide range of remote control protocols and consumer‑grade IR devices. Constructed with a robust PCB substrate and coated with a protective epoxy finish, the units resist moisture, dust, and minor mechanical stress, extending their lifespan in both prototype and semi‑permanent installations. Pin definitions are simple: Output, VCC, and GND, with an on‑board LED that visually confirms signal activity, making debugging and iterative development faster and more intuitive.
Usage
These modules excel in a variety of environments, from classroom labs where students experiment with line‑following robots, to professional prototyping labs developing custom remote‑control interfaces for home automation. The compact form factor (3.94 x 1.97 x 0.79 inches) and lightweight design (1.06 ounces per module) allow seamless integration into Arduino, Raspberry Pi, AVR, ARM, and 8051‑based platforms. Whether you are building a DIY infrared TV remote, a wireless sensor network, or an IR‑based data link for IoT devices, the kit provides the necessary hardware to transmit and receive commands reliably. The included Dupont cables simplify wiring, reducing setup time and minimizing the risk of connection errors. The LED indicator on each module offers immediate visual feedback, which is especially valuable during field testing or when troubleshooting signal integrity issues.

FAQ
What microcontroller platforms are compatible with these modules?
The modules work with any platform that provides a 5V supply and digital I/O pins, including Arduino, Raspberry Pi, AVR, ARM Cortex, and 8051 families.
Do I need additional components to decode IR signals?
Yes, you will need a suitable IR decoding library or firmware on your microcontroller. Popular Arduino libraries such as IRremote can be used to interpret the received signals.
Can the modules be used in a noisy electrical environment?
Both the receiver and transmitter are designed with filtering and shielding to tolerate typical electromagnetic interference, but for extremely noisy environments we recommend adding external capacitors or using twisted‑pair wiring.
Is there a warranty or return policy?
DKARDU offers a 30‑day replacement warranty for any defective units, along with technical assistance to help resolve any integration issues you may encounter.
How do I power the modules safely?
Connect the VCC pin to a stable 5V source and the GND pin to ground. The modules draw minimal current, making them safe for battery‑powered projects as well as mains‑derived supplies.
