Stepper Motor Driver Controller Boards for Arduino

Robomart have huge inventory of stepper motor driver controller boards. But here we describe mostly usable stepper motor drivers.
  • ULN2803 Stepper Motor Driver Controller Board
  • BTS7960B High Bridge 43A Stepper Motor Driver Controller Board

ULN2803 Stepper Motor Driver Controller Board

Stepper motor is used to provide a rotation to the motor through multiple electromagnetic coils that work individually. In robotics, it’s of huge importance including spinning of forward and backward in discrete steps or continuous rotation, accurate positions and ability to control with or without feedback. It consists of 8 I/O coils that can go through 500mA with 50V supply.

The ULN2803 is a high-voltage, high-current transistor array. The device consists of eight NPN pairs characterizing high-voltage outputs with common-cathode clamp diodes for switching inductive loads. The collector-current rating of each pair comprise of 500 mA. The Darlington pairs may be connected in parallel for higher current capability.

It deals with various projects which we present before you include modular cheap micro mouse home automation board, LED matrix project using shift register and PIC.

ULN2803 Board Features
  • Large DC voltage gain-100dB
  • Very low current supply
  • Frequency is internally compensated
  • Low input offset voltage – 2mV
  • Low input bias current – 20nA
  • Differential input voltage range equal to the power supply voltage
It’s mostly used in stepper motor additionally it’s easily available in relay drivers, hammer drivers, lamp drivers, display drivers, line drivers and logic buffers. ULN2803 used in Arduino board which helps stepper motor effectively without damaging board.

BTS7960B H-bridge 43A high-power motor driver Module

This driver uses BTS7960B chip that is composed of high power H-bridge driver module having thermal over-current protection. Basically it is a apart of Novalith family containing one p-channel high side MOSFET and one N-CHANNEL low side MOSFET with an integrated driver IC in one package. Due to strong braking and drive in this circuit successfully isolate microcontroller and motor driver with high current i.e.43Ampere.

It’s a fully integrated high current module with Operating Voltage of 24V And Continuous current of 43A Max and PWM capability of up to 25 kHz. BTS7960 IC has good power protection. Interfacing to a microcontroller is made easy by the integrated driver IC which features logic level inputs, diagnosis with current sense, slew rate adjustment, dead time generation and protection against over temperature, overvoltage, under voltage, over current and short circuit .The BTS 7960 is protected against over temperature by an integrated temperature sensor which further leads to shut down of both O/P stages.

The BTS 7960 is best known for its cost optimized solution for protected high current PWM motor drives with very low board space utilization. One wheeled electric personal transporter is a very common project for transporter.
