A non-contact magnetic field sensor with a range of ±1.5 mT and a sensitivity of 1500 mV/mT at 5 V. It offers an analog ratiometric output and a flag signal activated when field thresholds are exceeded. It features a fast response time (20 µs) and a 30 kHz bandwidth with a built-in RC filter. Its compact design, AC/DC capability, and easy mounting make it ideal for energy-efficient and safe current monitoring systems. Pololu 5352

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

HK 3D Printer Hot Plate MK2B Dual Power RepRap Mendel and RAMPS Compatible (46896)

These 17 mm long aluminum adapters convert a 3 mm diameter shaft to a 12 mm hex shaft that compatible with many common hobby RC wheels. The set includes two adapters, two M4 screws for securing wheels to the adapters, four M3 set screws for securing the adapters to motor shafts, and one 1.5 mm Allen wrench for use with the set screws.

The RoboClaw motor controller can control a pair of brushed DC motors using USB serial, TTL serial, RC or analog inputs. Integrated dual quadrature decoders make it easy to create a closed-loop speed control system. This version can supply a continuous 7.5 A per channel (15 A peak). Pololu 3284
