| Issue | Implication | |-------|-------------| | | Users often overload the L293D (600mA continuous, 1.2A peak per channel) because the datasheet doesn’t emphasize limits. | | Missing voltage drop specs | L293D drops ~1.4V–2V, reducing torque at low battery voltages – not explained. | | No flyback diode specification | While onboard diodes exist, no guidance on adding external Schottky diodes for inductive kickback. | | PWM frequency limits | Doesn’t state max PWM frequency (L293D works <5 kHz typically). Users may apply 20 kHz+ and get poor response. | | Schematic errors | Many clone datasheets have mismatched pin labels (e.g., swapping ENA/ENB). | Servo Headers To drive 4 unidirectional motors (e
