IR Transmitter

This AX22-sized board carries a high-efficiency IR26-61C/L302/TR8 940 nm infrared LED on a compact 22 × 22 mm PCB. Designed for 38 kHz modulated signal output, it enables your microcontroller to send commands to TVs, audio systems, projectors, and other IR-controlled devices using standard protocols. An onboard current-limiting resistor and visible TX status LED make it plug-and-play with Arduino IDE, MicroPython PWM output, or MicroBlocks IR blocks. Ideal for DIY remotes, learning systems, or sending simple commands between AX22 boards.
