This powerful synchronous switching step-down (or buck) regulator takes an input voltage of up to 50 V and efficiently reduces it to 12 V. The board measures only 1″ × 1″ yet delivers typical maximum continuous output currents between 2.3 A and 6.5 A, depending on the input voltage, which makes it well suited for powering moderate to large loads. An optional enable input with a precise cutoff threshold can be used to put the regulator in a low-power state with a current draw of 10 µA to 20 µA per volt on VIN. The regulator also features reverse voltage protection and a power-good output that indicates when the regulator cannot adequately maintain the output voltage.

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 board is a simple carrier of Broadcom’s bidirectional ±50A ACHS-7124 Hall effect-based linear current sensor, which offers a low-resistance (~0.7 mΩ) current path and electrical isolation up to 3 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 ±1.5%. It operates from 4.5 V to 5.5 V and is intended for use in 5 V systems.

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).
