This board is a simple carrier of Broadcom’s ±10A ACHS-7121 Hall effect-based linear current sensor, which offers a low-resistance (~0.7 mΩ) current path and electrical isolation up to 3 kV RMS. This version accepts a bidirectional...

This board is a simple carrier of Broadcom’s ±30A ACHS-7123 Hall effect-based linear current sensor, which offers a low-resistance (~0.7 mΩ) current path and electrical isolation up to 3 kV RMS. This version accepts a bidirectional...

The A-Star 32U4 Prime LV is a programmable board based on the ATmega32U4 AVR microcontroller and arranged in the common Arduino form factor. The A-Star Prime offers many additional features and improvements over competing products,...

These side-entry terminal blocks have terminals that hold and release wires through the simple adjustment of a small screw, allowing you to easily make temporary connections to a PCB. Since each terminal has a single corresponding pin...

This small synchronous switching step-down (or buck) regulator takes an input voltage of up to 50 V and efficiently reduces it to 12 V . The board measures only 0.7″ × 0.8″ yet delivers typical maximum continuous output currents between...

This NEMA 17-size hybrid bipolar stepping motor has a 1.8° step angle (200 steps/revolution). Each phase draws 1.7 A at 2.8 V, allowing for a holding torque of 3.7 kg-cm (51 oz-in). This hybrid bipolar stepping motor has a 1.8° step...

The Tic T249 USB Multi-Interface Stepper Motor Controller makes basic control of a stepper motor easy, with quick configuration over USB using our free software. The controller supports six control interfaces: USB, TTL serial, I²C,...

This powerful step-up/step-down regulator efficiently produces a fixed 24 V output from input voltages between 3 V and 30 V while allowing a typical output current of up to 2 A when the input voltage is close to the output voltage and...

This small synchronous switching step-down (or buck) regulator takes an input voltage of up to 50 V and efficiently reduces it to 5 V . The board measures only 0.7″ × 0.8″ yet delivers typical maximum continuous output currents between...

This small synchronous switching step-down (or buck) regulator takes an input voltage from 4.5 V to 50 V and efficiently reduces it to 3.3 V . The board measures only 0.7″ × 0.8″ yet delivers typical maximum continuous output currents...

These boost (step-up) voltage regulators generate higher output voltages from input voltages as low as 2.9 V. They are switching regulators (also called switched-mode power supplies (SMPS) or DC-to-DC converters) and have a typical...
