Gm4e01 Jun 2026

The GM4E01 is a designed for infrared remote control systems. It receives modulated IR signals (typically 38 kHz or 40 kHz) from a remote control, amplifies them, demodulates them, and outputs the digital data signal for a microcontroller (e.g., Arduino, ESP32, PIC).

#define IR_RX_PIN 11

void setup() Serial.begin(9600); IrReceiver.begin(IR_RX_PIN, ENABLE_LED_FEEDBACK); gm4e01

Always verify pinout before soldering.
