IR Transmitter

This 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. Use it standalone with any microcontroller, or snap it into the Genesis Modular system from Axiometa for plug-and-play integration. Works with Arduino IDE, MicroPython, or MicroBlocks.
