The SCTX2B/RX2BD have five control keys controlling the motions ( i.e. forward, backward, rightward, leftward, and the turbo function ) of the remote controlled car. Absolute Maximum Ratings DC Supply Voltage-----------------------------0.3V to 5.0V Input/Output Voltage---------------------------GND –0.2V to VDD+0.2V Operating temperature------------------------- -10℃ to 60℃ Storage Temperature---------------- -25℃ to 125℃ Comment* Never allow a stress the values listed under “Absolute Maximum Ratings”, otherwise the device would suffer from a permanent damage. Nor is a stress at the listed value be allowed persist over a period, since an extended exposure to the absolute maximum rating condition may also affect the reliability of the device, if not causing a damage thereof.
