EX-MotorShield8874
EX-MotorShield8874 is an open source PCB design by DCC-EX: a 4-layer, 65.9 × 52.9 mm board with 75 components (31 distinct parts). It is built around the 74HC04, 74HC08, 74HC32, DRV8874PWPR and more. Filed under robotics & motion and dev boards & breakouts and power & battery.
Design files for the open source 5A Motor Shield
The EX-Motorshield8874 is a pin compatible with the original Arduino Motor Shield Rev3 but provides significantly improved electrical performance for driving higher loads, with lower power dissipation, and improved usability.
The EX-Motorshield8874 is based on two DRV8874 H-bridge motor drivers with integrated current sensing from Texas Instruments (TI). It is used to drive inductive loads like relays, solenoids, DC and stepping motors.
