MOT-SM-17 NEMA 17 Compatible Stepper Motor for 3D Printers and CNC XYZ
US$18.15
A NEMA 17 stepper motor is a stepper motor with a 1.7 x 1.7 inch (42.3 x 42.3 mm) faceplate. The NEMA 17 is larger and generally heavier than for example a NEMA 14, but this also means it has more room to put a higher torque.

TEST-110 3 Channel Servo/ESC Tester 4.8V – 6VDC
US$5.59

This module is designed to test servo motors and electronic speed controllers (ESC). On the bottom of the Output signal the select push button allows users to toggle in three modes. Mode 1) Potentiometer Control to evaluate the reaction time of the output motor manually. Mode 2) Neutral mode to deactivate the tester and allow the speed controller directly control the motor. Mode 3) Automatic to allow the signal to be digitally controlled by the tester. You can connect up to three servos on the output side and be controlled by one input signal.

DRI0043 TB6600 Stepper Motor Driver
US$30.00
TB6600 is an easy-to-use professional stepper motor driver, which could control a two-phase stepping motor. It is compatible with Arduino and other microcontrollers that can output a 5V digital pulse signal. TB6600 stepper motor driver has a wide range power input, 9~42VDC power supply. And it is able to output 4A peak current, which is enough for the most of stepper motors. The stepper driver supports speed and direction control. You can set its micro step and output current with 6 DIP switch. There are 7 kinds of micro steps (1, 2 / A, 2 / B, 4, 8, 16, 32) and 8 kinds of current control (0.5A, 1A, 1.5A, 2A, 2.5A, 2.8A, 3.0A, 3.5A) in all. And all signal terminals adopt high-speed optocoupler isolation, enhancing its anti-high-frequency interference ability. As a professional device, it is able to drive 57, 42-type two-phase, four-phase, hybrid stepper motor.

DFR0398 Romeo BLE Quad - A STM32 Control Board with Quad DC Motor Driver & Bluetooth 4.0
US$69.83
Romeo BLE Quad is an arduino compatible robot controller based on STM32 ARM chip. It inherits all features from the Bluno M3, including wireless programming support, wireless communication between iOS/Android apps and remote control. Beyond this it also includes a 4-way DC motor driver and encoder interfaces. You can implement a robot with PID closed-loop feedback control directly with our TT Geared Motor. As well as this the Romeo BLE Quad offers powerful performance thanks to the STM32 ARM 32-bit microcontroller with more storage space and more interface resources. DFRobot has developed bespoke firmware to make it compatible with Arduino IDE and accessible to beginners to robotics.

SERVO-SR Servo Signal Reverser
US$5.59
This device is designed to reverse the incoming signal to the servo. If you have two servos connected with a y cable and both servos move clockwise in order to get the other one to movement the opposite this cable will be connected from the y cable to the servo to reverse the direction! Great for the Y cable scenarios or for RC vehicles. Recommend to use a heat shrink tube to insulate and protect the IC, added benefit makes this job look like a clean one.

AM-124 Reed Switch Module for 5v Microcontrollers
US$3.07
This module is a simple Reed switch that comes with a simple circuit to translate the analog signal into a digital signal using the LM393 voltage comparator onboard. You can also choose to bypass the comparator and simply use the analog signal being outputted by the circuit on pin A0. Holding the board with the pins facing towards you, the left most pin labelled A0 is for analog output. The inner left pin labelled G is ground and on the inner right labelled + is for 5vdc supply. The outer right pin labelled D0 is for digital output.
