The Tic 36v4 USB Multi-Interface High-Power Stepper Motor Controller makes basic control of a stepper motor easy, with quick configuration over USB using our free software. The controller supports six control interfaces: USB, TTL serial, I²C, analog voltage (potentiometer), quadrature encoder, and hobby radio control (RC). This version incorporates a discrete MOSFET stepper motor driver, and male headers and terminal blocks are included but not soldered. It can operate from 8 V to 50 V and can deliver up to approximately 4 A per phase without a heat sink or forced air flow (or 6 A max with sufficient additional cooling).

This breakout board makes it easy to use Toshiba’s TB67S128FTG microstepping bipolar stepper motor driver, which features adjustable current limiting and microstepping down to 1/128-step. In addition, it has the ability to dynamically select an optimal decay mode by monitoring the actual motor current, and it can automatically reduce the driving current below the full amount when the motor is lightly loaded to minimize power consumption and heat generation. The driver has a wide operating voltage range of 6.5 V to 44 V and can deliver approximately 2.1 A per phase continuously without a heat sink or forced air flow (up to 5 A peak). It features built-in protection against under-voltage, over-current, and over-temperature conditions; our carrier board also adds reverse-voltage protection (up to 40 V).

This discrete MOSFET stepper motor driver enables control of one bipolar stepper motor. It supports a wide 8 V to 50 V operating voltage range and can deliver up to 4 A continuous per phase without a heat sink or forced air flow (6 A max with sufficient additional cooling). The SPI interface allows configuration of the current limiting, step mode (9 step modes from full-step through 1/256-step), decay mode, and stall detection. The driver also provides back-EMF feedback that can be used for more advanced control and stall detection algorithms. Additional features include reverse-voltage, under-voltage, and over-current protection.

This board is a simple carrier of Allegro’s bidirectional ±20A ACS724LLCTR-20AB Hall effect-based linear current sensor, which offers a low-resistance (~1.2 mΩ) current path and electrical isolation up to 2.4 kV RMS. This version accepts a bidirectional current input with a magnitude up to 20 A and outputs a proportional analog voltage (100 mV/A) centered at 2.5 V with a typical error of ±0.8%. It operates from 4.5 V to 5.5 V and is intended for use in 5 V systems.

This board is a simple carrier of Allegro’s unidirectional 10A ACS724LLCTR-10AU Hall effect-based linear current sensor, which offers a low-resistance (~1.2 mΩ) current path and electrical isolation up to 2.4 kV RMS. This version accepts a unidirectional current input up to 10 A and outputs a proportional analog voltage (400 mV/A) that measures 500 mV when the input current is zero. The typical output error of ±1.5%. It operates from 4.5 V to 5.5 V and is intended for use in 5 V systems.

This 12 V light-duty (LD) linear actuator with a 5:1 gear reduction can lift loads up to 15 kgf [34 lbs or 150 N] and can withstand static loads up to 250 kgf [550 lbs or 2500 N]. It has a maximum speed of 43.9 mm/s [1.73″/s] at no load and 36.5 mm/s [1.44″/s] at the maximum load. Limit switches at each end make the actuator easy to control over its full range of motion. The shaft holds its position when unpowered. This version has a 10-inch stroke (9.8″ usable) and a feedback potentiometer that lets you determine where the actuator is in its stroke.

This gearmotor consists of a high-power, 12 V brushed DC motor combined with a 74.83:1 metal spur gearbox, and it has an integrated 48 CPR quadrature encoder on the motor shaft, which provides 3591.84 counts per revolution of the gearbox’s output shaft. The gearmotor is cylindrical, with a diameter just under 25 mm, and the D-shaped output shaft is 4 mm in diameter and extends 12.5 mm from the face plate of the gearbox. This gearmotor is also available without an encoder.

This is the motor and encoder portion of our high-power (HP), 12V 25D mm metal gearmotors with 48 CPR encoders. It does not include a gearbox, but the pinion gear on the output shaft works with all of our 25D mm gearmotor gearboxes, so this can be used as a replacement motor or encoder for those gearboxes.
