Ruth's sister 38kHz IR IRDA to TTL Converter International Power Cord

SKU CH-3FSA-N2RRX

Converts 38 kHz infrared IRDA signals to TTL logic levels for serial communication

  • IR-to-TTL conversion at 38 kHz carrier frequency
  • Far-infrared communication module for serial data links
  • Compact adapter bridges IRDA and logic-level devices
  • New condition ensures reliable out-of-box operation

38kHz IR to TTL Converter

This module converts 38kHz infrared signals to TTL logic levels for serial communication. It suits developers adding IR remote control or data links to microcontroller projects. The adapter bridges consumer IR protocols and embedded UART interfaces without extra circuitry.

Sustained Infrared Reception

Continuous IR streams at the rated carrier frequency are decoded to steady TTL output without timing drift. The design handles repeated bursts from remote controls or beacons while maintaining signal integrity. Users needing modulation schemes outside 38kHz or high-speed IrDA standards will require different hardware.

Questions about this item

How much heat does the 38 kHz IRDA converter generate during continuous use?

The module is a passive infrared-to-TTL adapter with no active cooling, so it produces negligible heat when running all day.

Which connector must my target device provide for the 38 kHz IRDA converter to work?

A standard TTL-level serial port (RX, TX, GND) is required on the host device for the converter to communicate.
