The VS1838B is an IR receiver module that detects modulated infrared remote-control signals and outputs a digital signal on OUT. It is typically connected with VCC, GND, and a microcontroller GPIO for reading IR commands.
| Pin | Signal | Description |
|---|---|---|
OUT |
digital | Demodulated IR receiver output — connect to a microcontroller digital input |
GND |
ground | Ground reference for the IR receiver module |
VCC |
power | Positive supply for the IR receiver, typically 3.3V or 5V |
| From | To | Wire |
|---|---|---|
board:5V |
x1:VCC |
