The motor driver is based on the popularL298 chip. It has a peak current of 2A per motor and can be controlled via TTL from any microcontroller with 3.3-5V inputs. The on-board 78M05 5V regulator can be used to supply logic power of ~450mA to the board or external microcontroller with a supply of 7-35V.
Motor connections, power and ground are made easily using the screw terminals while logic connections are provided on a 0.1" header for easy connection using jumper leads.
LED's are provided to show motor direction and power supply.
Input voltage range Vs: +5 V-+35 V. If the on-board regulator is used to supply external components then the supply range is +7 V ~ +35 V.
Peak current:2A per motor. In practice this will depend on ambient conditions and air flow. Maximum power consumption in total is 20W.
Logic voltage Vss: +5 V ~ +7 V ( power taking from board: +5 V)
Power consumption for logical part: 0 ~ 36mA
Control signal input voltage range:
Low:-0.3V ≤ Vin ≤ 1.5V
High: 2.3V ≤ Vin ≤ Vss
Enable signal input voltage range:
Low: -0.3 ≤ Vin ≤ 1.5V (control signal is invalid)
High: 2.3V ≤ Vin ≤ Vss (control signal)
Maximum power consumption: 20W (temperature T =75ºC)
