Multi-channel Motor Output 2 channels of DC motor output, supporting forward rotation, reverse rotation, braking, stop and other modes. PWM frequency up to 100 kHz max. High-current Driving Capability The TB6612FNG chip delivers a continuous output current of up to 1.2A per channel, with a peak starting current of 2A/3.2A, meeting the requirements of most small vehicles and stepper motors. Rich Interfaces Micro:bit pins are extended via 3PIN (VCC/GND/Signal) interfaces. A UART communication interface is also provided for easy connection of Bluetooth modules or other serial devices. Regulated Power Supply On-board 3.3V and 5V voltage regulator chips supply power to the micro:bit, the expansion board itself, and other peripherals simultaneously. Specification Input Voltage DC 6-12V (recommended to match the rated voltage of the motor used) Driving Current Continuous operating current per channel ≤ 1.2A Peak Current 2A/3.2A for starting or short-term peak operation Driver Chip TB6612FNG (dual H-bridge driver) Compatible Motherboards BBC micro:bit (V1 / V2) Interface Type 3PIN interface + motor terminals + UART extension + external power terminal Operating Environment 10℃ ~ +50℃ Color: Red Material: PCB Package Contents: 1*Module Only the above package content, other products are not included.
