Product parameters: 1. Drive chip: L298N dual H-bridge DC motor driver chip 2. The drive portion of the terminal supply area Vs: + 5V ~ + 35V; such as the need to take power within the board, the power supply range Vs: + 7V ~ + 35V 3. Drive section peak current Io: 2A The logical part of the terminal supply area Vss: + 5V ~ + 7V (can take power within the board + 5V) 5. The logical part of the operating current range: 0 ~ 36mA 6. Control signal input voltage range: Low: -0.3V<=Vin<=1.5V High: 2.3V<=Vin<=Vss 7. enable signal input voltage range: Low: -0.3<=Vin<=1.5V (control signal is invalid) High: 2.3V<=Vin<=Vss (control signal active) 8. Maximum power consumption: 20W (when the temperature T = 75 ) 9. Storage temperature: -25 ~ + 130 10. The driver board size: 55mm * 49mm * 33mm (with fixed copper pillar and heat sink height) 11. The driver board Weight: 33g 12. Other expansion: control direction indicator, take electrical interface within the logic portion of the plate.
