This basic 2-channel relay carrier board makes it easy to incorporate two single-pole, double-throw (SPDT) “sugar cube”-style power relays into your electronics project. Integrated MOSFETs allows the relays to be controlled with low-current digital inputs, and indicator LEDs show when the relays are activated. The four control pins are accessible via a top-entry JST SH-style connector that works with our selection of 4-pin JST SH-style cables, and the switch pins are available for use with 5mm-pitch terminal blocks or 0.2″-spaced pins. Note: Relays not included.

The Pololu basic 2-channel relay carrier modules allow simple, independent control of two single-pole, double-throw (SPDT) switches from low-voltage, low-current control signals. This item includes the basic carrier PCB with two soldered-in 12 V relays, 5mm-pitch terminal blocks for the switch connections, and a top-entry JST SH-style connector for the control connections that works with our selection of 4-pin JST SH-style cables. The included power relays are Omron G5LE-14-DC12 and are rated for up to 10 A under most conditions.

This sensor uses an IR LED and a phototransistor to measure the light reflected from nearby surfaces. It operates from 2.9–5.5 V, with dimmable brightness control independent of the supply voltage. The optimal range is <5 mm, but it can detect high-reflectance objects out to around 80 mm. This version features a high-performance QTRXL sensor, with lenses and a high-brightness emitter for extra-long range, and a connector that works with our 4-pin JST SH-style cables (compatible with SparkFun’s Qwiic and Adafruit’s STEMMA QT cables, but the interface is not I²C).

This discrete MOSFET brushless motor controller is based on Allegro’s A89301 BLDC driver and enables sensorless control of one brushless DC motor. It supports a wide 5.5 V to 48 V operating voltage range and can continuously deliver up to 11 A motor current without a heat sink or forced air. The A89301 supports four control interfaces: analog voltage, PWM duty cycle, pulse frequency, and I²C. The I²C interface also allows configuration of various settings on the A89301, and we provide a configuration utility for Windows that simplifies setup with one of our USB-to-I²C adapters. This version ships with soldered header pins and terminal blocks.
