บอร์ด Drive motor สามารถขับ motor ได้ 2 ตัว ทนกระแสได้ 1.2 A
บอร์ดมีขนาดเล็ก
ราคา 90 บาท
Features:
- Power supply voltage: VM=15V max, VCC=2.7-5.5V
- Output current: Iout=1.2A(average) / 3.2A (peak)
- Standby control to save power
- CW/CCW/short brake/stop motor control modes
- Built-in thermal shutdown circuit and low voltage detecting circuit
- All pins of the TB6612FNG broken out to 0.1" spaced pins
- Filtering capacitors on both supply lines
