Add remote-control input to any AX22 build in seconds. This board hosts a IRM-V538M3/TR138 kHz IR demodulator on a compact 22 × 22 mm PCB, giving your microcontroller a clean, decoded active-low pulse stream that’s immune to ambient light and power-line noise. A status LED is already fitted, so you can plug straight into an Arduino IDE, IRemote sketch, a MicroPython pulse-in decoder, or a MicroBlocks “IR Receiver” block with zero extra parts.
