Toshiba TB6612FNG dual H-bridge breakout board — a compact, efficient MOSFET-based motor driver for two small DC motors or one bipolar stepper, controllable from any 3.3V/5V microcontroller.
| Logic supply (VCC) | 2.7–5.5V |
| Motor supply (VM) | Up to 13.5–15V |
| Continuous current | 1.2A per channel |
| Peak current | 3.2A per channel |
| PWM frequency | Up to 100kHz |
| Protection | Thermal shutdown, low-voltage detection |
| Board size | 21mm x 20mm x 3mm |
Sizing note for sumo builders: at 3.2A peak per channel, this driver is well matched to small line-follower or maze-solver motors, N20-class micro gearmotors, or low-current auxiliary functions — but it is undersized for driving an overvolted Core-class mini sumo motor at competition current. A Core motor at 4S can pull 9–14A at stall, several times this board's peak rating. Use this driver for sensors, weapons/servos, or secondary motors; use a higher-current driver (MOSFET H-bridge stage or ESC) for your main drive motors.
