there are some GPIOs on the KC868-AG PCB board. you will see text on the pcb, some are "IOxx", some are "Ixx" . "IOxx" means the pin you can use for "input" and "ouptut", if "Ixx" only use for "input" , not for "output".
so make sure you have using the "IOxx" for IR extend, because IR signal is "output" type.
