PT8A973 Overview
The PT8A9702P works as encoder, it can provide 8direction remote control for toy car application with PT8A973/973L/PT8A974/974L together. Input 8direction named F, FL, L, BL, BR, R, FR, and B they are bined with F, L, B, and R four signals. In decoder side, use output signal Left & Right to drive Right Motor, and use For & Back to drive Left Motor.
