【2-in-1 TF Card Adapter】Designed specifically for Raspberry Pi B+/2B/3B;
【Double Switch System】It has a dual switch system and can use two TF cards at the same time;
【Wireless/remote/infrared remote contro】Changing the DIP switch to Arduino-compatible board or microcontroller GPIO control can help you realize wireless/remote/infrared remote control system, etc.
This 2IN1 Two TF cards commutator is specially designed for Raspberry Pi B+/2B/3B with double switch systems. You could enjoy the convenience of using two TF cards at the same time to transfer to different systems for playing at the poking of the switch. Moreover, if you could change the dial switch to Arduino or SCM GPIO controlled, it could help you realize wireless/ remote/ infrared remote control system, etc.
Note: It should be used when off power or its system will be damaged when on power to switch.
