Generic Black IR Remote Control (CR2025)

This IR remote is broadly compatible with any platform that can interface with a standard 38kHz IR receiver module, such as the common TSOP382. This includes Arduino boards using libraries like IRremote, Raspberry Pi with GPIO input, ESP8266/ESP32 for IoT projects, and other microcontrollers. You simply need to wire the receiver module's output pin to a digital input pin on your board and use a library to decode the NEC or similar protocol signals sent by the remote's buttons.

The remote requires a single 3V CR2025 coin cell battery, which is not included. Battery life depends on usage frequency due to the low 3-5µA standby current and 3-5mA active transmission current. With typical intermittent use in a project, a battery can last several months to over a year. For optimal performance, ensure the battery contacts are clean and the battery is properly seated with the correct polarity (+ side facing up towards the buttons) before use.

No, this is a fixed-code, consumer-grade IR remote. The button codes are hardcoded at the factory using an internal chip and cannot be reprogrammed. To use it in your project, you must first capture and identify the unique hex code transmitted by each button using your microcontroller and an IR receiver library. Once identified, you can map those codes to specific actions in your firmware. For a programmable remote, you would need a different device designed for learning and transmitting custom codes.
