L293D H-Bridge
Your esieabot (from 2020 to 2022) is equipped with an L293D H-bridge enabling it to control these 2 dc motors in all directions.
Operation
The L293D is an H-bridge that can control 2 motors at the same time.
Depending on which inputs are activated, the motors will turn in one direction or the other.

Connection
For each motor, connect the following inputs and outputs:
enable input: enables or disables a motor
Input 1 (or 3): to operate the motor in one direction
Input 2 (or 4): to operate the motor in the other direction
Output 1 (or 3): one of the motor terminals
Output 2 (or 4): the other motor terminal
Note
Note that there is no defined direction through the H-bridge. The + and - motor terminals and the forward/reverse direction are purely arbitrary.
