Do you want to build a robot using lots of servo motors like a hexapod? Run out of PWM outputs on your micro or using a Raspberry Pi? Maybe you just want to control LEDs with 12-bits of PWM brightness levels? Then this is the module you have been looking for!
The Arduino Motor Shield uses L293D motor drivers and a 74HC595 shift register to drive 2 servo motors and 2 stepper motors or up to 8 half-bridge drivers.
The Romeo BLE is an Arduino Robot Control Board with Bluetooth 4.0 capabilities, featuring an onboard 2-way H-bridged motor driver for robotics.
These TMC2208 Drivers are SMD IC components for repairing faulty modules, with a full suite of features for effective driving of 2-phase steppers.
The DRV8825 Stepper Driver IC is a handy replacement part, letting you fix faults and get back to fabricating without replacing the entire module.
The tiny Romeo BLE Mini from DFRobot is a bite-sized version of the amazing Romeo BLE, made for tiny robots that need big brains.
