A IR LED transmitter module with PWM signal generation and a simple 33Khz IR signal receiver module together. The PWM signal is generated by the 55 IC on board. By this the firmware on the microcontroller is fairly easy to implement.

Motherboard Interface:
2 pin: TX, RX.

Voltage:

• 5V
• 3,3V

Features:

• Hardware PWM signal gerneration
• TX status LED
• RX status LED
