Review on ๐Ÿš— DEVMO BTS7960B 43A Double DC Stepper Motor Driver Module H-Bridge PWM Smart Car| Ar-duino,Raspberry Pi Compatible by Mike Ken

Revainrating 1 out of 5

Out of spec: Computers and accessories

1. The resistor Rs (current sense resistor) soldered on the board to pin 6 of the BTS7960 is 10kฮฉ while the datasheet of the BTS7960B says 1kฮฉ. 10K will result in an excessively high voltage that is beyond the range of most CPU inputs (unless scaled) when driven at high current.2. This company doesn't offer programs for a fee - I had to take it from another competitor.3. The screen print on the power supply and motor connector is reversed - a small but poor quality control issue.

Pros
  • even oldtimers understand
Cons
  • Some little things
