Type: Dual full H‐bridge driver
Motor Voltage Range: 5–35 V
Logic Voltage: 5 V (TTL compatible)
Current Capacity: Up to 2 A continuous per channel, 3 A peak (with heatsink)
Control Signals:
IN1/IN2, IN3/IN4 → Direction control
ENA/ENB → Enable pins (PWM for speed control)
Voltage Drop: ~1.5–2.5 V (due to bipolar transistors, reduces efficiency)
Onboard Regulator: 78M05 provides 5 V logic supply when motor voltage ≤ 12 V
Protection: Thermal shutdown and current sensing pins availabl
