Add quadrature encoders to your micro metal gearmotors (extended back shaft version required) with this kit that uses a magnetic disc and hall effect sensors to provide 12 counts per revolution of the motor shaft. The sensors operate from 2.7 V to 18 V and provide digital outputs that can be connected directly to a microcontroller or other digital circuit. These encoders have a side-entry, 6-pin male JST SH-type connector, and we have cables that work with them available in several lengths (12 cm, 30 cm, and 75 cm). This module is compatible with all of the dual-shaft micro metal gearmotors we carry, including the HPCB versions.

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 ±50A ACS724LLCTR-50AB 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 50 A and outputs a proportional analog voltage (40 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.
