    This module features a fixed-gain, 38 kHz modulated IR sensor and a corresponding IR LED with oscillator circuit to make a tiny proximity sensor. This low-brightness version draws an average of 8 mA at 5 V and has a typical sensing range up to approximately 12 inches (30 cm).

  • CHF16.67

    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 small synchronous switching step-down (or buck) regulator takes an input voltage of up to 36 V and efficiently reduces it to 5 V. The board measures only 0.7″ × 0.7″ yet delivers typical continuous output currents between 1.9 A and 2.5 A, depending on the input voltage, which makes this regulator well suited for powering moderate loads like sensors or small motors. An optional enable input can be used to put the regulator in a low-power state with a current draw of 5 µA to 10 µA per volt on VIN. The regulator also features reverse voltage protection and a power-good output indicates when the regulator cannot adequately maintain the output voltage.

  • CHF10.17

    This small synchronous switching step-down (or buck) regulator takes an input voltage of up to 36 V and efficiently reduces it to 7.5 V. The board measures only 0.7″ × 0.7″ yet delivers typical continuous output currents between 1.6 A and 2.4 A, depending on the input voltage, which makes this regulator well suited for powering moderate loads like sensors or small motors. An optional enable input can be used to put the regulator in a low-power state with a current draw of 5 µA to 10 µA per volt on VIN. The regulator also features reverse voltage protection and a power-good output indicates when the regulator cannot adequately maintain the output voltage.

  • CHF25.95

    This carrier board for ST’s VNH5019 motor driver IC operates from 5.5 to 24 V and can deliver a continuous 12 A (30 A peak). It works with 2.5 to 5 V logic levels, supports ultrasonic (up to 20 kHz) PWM, and features current sense feedback (an analog voltage proportional to the motor current). Along with built-in protection against reverse-voltage, over-voltage, under-voltage, over-temperature, and over-current, these features make this product a great general-purpose motor driver.

    These universal aluminum mounting hubs allow you to mount custom wheels and mechanisms to 4 mm diameter motor shafts. The set includes two hubs, two #4-40 set screws for securing the hubs to motor shafts, and one 0.05″ Allen wrench for use with the set screws.

    Each hub has four threaded mounting holes for #4-40 screws (not included).

    This sensor is a carrier/breakout board for ST’s VL53L3CX laser-ranging sensor, which offers fast and accurate ranging up to 3 m. It uses the time of flight (ToF) of invisible, eye-safe laser pulses to measure absolute distances to multiple targets simultaneously, independent of ambient lighting conditions and target characteristics like color, shape, and texture (though these things will affect the maximum range). Distance measurements can be read through a digital I²C interface. The board includes a 2.8 V linear regulator and level-shifters that allow it to work over an input voltage range of 2.6 V to 5.5 V, and the 0.1″ pin spacing makes it easy to use with standard solderless breadboards and 0.1″ perfboards.

  • CHF10.17

    This small synchronous switching step-down (or buck) regulator takes an input voltage of up to 36 V and efficiently reduces it to 9 V. The board measures only 0.7″ × 0.7″ yet delivers typical continuous output currents between 1.5 A and 2.3 A, depending on the input voltage, which makes this regulator well suited for powering moderate loads like sensors or small motors. An optional enable input can be used to put the regulator in a low-power state with a current draw of 5 µA to 10 µA per volt on VIN. The regulator also features reverse voltage protection and a power-good output indicates when the regulator cannot adequately maintain the output voltage.

    This small synchronous switching step-down (or buck) regulator takes an input voltage of up to 36 V and efficiently reduces it to 6 V. The board measures only 0.7″ × 0.7″ yet delivers typical continuous output currents between 1.8 A and 2.5 A, depending on the input voltage, which makes this regulator well suited for powering moderate loads like sensors or small motors. An optional enable input can be used to put the regulator in a low-power state with a current draw of 5 µA to 10 µA per volt on VIN. The regulator also features reverse voltage protection and a power-good output indicates when the regulator cannot adequately maintain the output voltage.

    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. 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).
