Module with 1 QTRX type optocoupler with RC (digital) output. The module operates from 2.9 V to 5.5 V, detects objects at a distance of up to 30 mm. The sensor will be used in projects that require detection of changes in the ground, e.g. in linefollower robots. Pololu 4301

Female-female cable, 40 cm long, with JST-SH 6-pin plug on both sides. Suitable for micro DC motor encoders with gear. Pololu 4768

A compact Hall-effect current sensor that provides accurate DC and AC current measurement within a ±10 A range with galvanic isolation. It features an analog VOUT output with a sensitivity of 200 mV/A and a 150 kHz bandwidth, enabling fast and precise readings in dynamic systems. The module operates over a wide temperature range of -40°C to 125°C, and the low current path resistance (~1.6 mΩ) minimizes energy loss. Its small size and flexible mounting options make it ideal for prototyping, industrial systems, and space-constrained projects. Pololu 5442

A module that provides galvanically isolated, bidirectional I²C communication (SDA and SCL lines), protecting devices from misconnections and voltage differences. Thanks to the TI ISO1640B chip, it supports data transfer up to 1.7 MHz. Pololu 5391

Compact and efficient module designed for precise control of bipolar stepper motors, offering microstepping down to 1/32 step and maximum current up to 2 A in peak mode. Thanks to advanced features such as QuietStep (APFD) algorithm, built-in protections and pin compatibility with A4988, it is perfect for hobby, educational and industrial projects. Blue Edition version with four-layer board and 2 oz copper provides better heat dissipation, increasing reliability of operation even at higher loads. Pololu 5340

Adapter for the 6-pin JST SH connector (horizontal) with a pitch of 1 mm to the DIP holes, pitch of 2.54 mm. Pololu 4772

VL53L8CX sensor module that offers fast and accurate distance measurement up to 4 m via I²C or SPI digital interface. It can measure distances to multiple targets simultaneously, providing depth map data with a resolution of up to 8x8. The built-in power supply circuit allows operation in the voltage range from 3.2 V to 5.5 V. Pololu 3419

Step-Up DC-DC converter module. It has an input voltage of 1.3 to 16 V, an output voltage of 9 V and a maximum input of up to 2 A. Pololu 4944

The holder for 4 AA R6 batteries is an ideal solution for people who need a simple and reliable way to connect AA batteries to obtain a voltage of 6 V

A high-power miniature Pololu from the HP series. The motor with gear 210:1, shaft speed is 150rpm, torque is 3kg*cm (0.3Nm). The motor has an extended shaft which makes it easy to attach the encoder. Pololu 2216

Compact ISP programmer for AVR microcontrollers. Works with Atmel Studio, AVRDUDE and Arduino IDE environments, using the STK500 protocol. Has a USB-TTL adapter function. Pololu 3172

An efficient step-down converter that reduces the input voltage to 3.3 V at a maximum current of 100 mA, offering high efficiency due to low quiescent current (<20 μA). It supports input voltages from 3.3 V to 65 V, has a Power Good (PGOOD) function, an EN input for system shutdown, and short circuit and overheat protection, making it a reliable and energy-efficient solution. Pololu 5372

Mini Tamiya Plug with 10cm Leads, Female

The Step-UpU1V10F3 Buck Voltage Regulator module with output voltage 3.3V, input voltage range of 0.5-5.5V and a maximum output current of 1.2A. Pololu 2563

The module protects the load against reverse polarity to -60 V, but does not block reverse current, which is desirable in applications such as motor control. It uses the LM74500-Q1 controller and a MOSFET transistor. Thanks to its low impedance (10 mΩ), it supports currents up to 10 A continuous and 30 A transient, providing reliable protection and the possibility of easy assembly. Pololu 5380

STSPIN220 stepper motor driver module with a low voltage range of 1.8 ... 10V and 1.1A working current. The controller allows you to control the motor motion up to 9 different resolutions (up to 1/256 steps). Pololu 2876
