Module with 1 QTR 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 4141

Step-Down DC-DC converter module based on the D36V6F6 chip. Input voltage 6.2..50V, output voltage 6V (max. 600mA). Pololu 3793

This compact (0.4″ × 0.5″) switching step-down (or buck) voltage regulator takes input voltages up to 50 V and efficiently reduces them to 9 V while allowing for a maximum output current of 600 mA. It has a very low dropout, so it can be used with input voltages that are within a few hundred millivolts of its output.

Module with four gas sensors that allow the detection of CO, NO2, alcohol and volatile organic compounds (VOC). The board is equipped with a Grove connector and communicates via the I2C interface. Seeed Studio 101020820
