    Hello,

    do I need flyback diodes in circuit of L293D and 5V DC motor?
    Thanks!

    hi there SJ

    for the L293D version, no you don't, it has built in inductive transient suppression diodes
    its brother the plain L293 ( No D) does require external diodes across the motors being driven
