Description
Equivalent
- DRV8825 (Texas Instruments)
- A4988 (Allegro MicroSystems)
- TMC2208/TMC2209 (Trinamic, more advanced)
- LV8729 (ON Semiconductor)
These chips offer similar functionality for stepper motor control, with variations in current handling, microstepping, and features like silent operation (TMC series). Choose based on voltage/current requirements and application needs.
Features
- 8-bit AVR RISC architecture for efficient processing.
- 8KB Flash memory for program storage.
- 512B SRAM & 512B EEPROM for data retention.
- 12MHz max operating frequency with low power consumption.
- 23 programmable I/O pins for versatile interfacing.
- 10-bit ADC (8 channels) for analog signal processing.
- USART, SPI, and I²C for serial communication.
- Two 8-bit & one 16-bit timers for precise timing control.
- Wide voltage range (2.7V–5.5V) for flexible power options.
- Low-power modes (Idle, Power-down) for energy efficiency.
Ideal for embedded systems, IoT devices, and battery-powered applications.
Pinout
- Pins 1-4 (A1, A2, B1, B2): Connect to the stepper motor coils.
- Pins 5-8 (GND): Ground connections.
- Pin 9 (VREF): Sets current limit via an external resistor.
- Pin 10 (VM): Motor power supply input (typically 5V–35V).
- Pins 11-14 (IN1–IN4): Logic inputs to control motor direction and stepping.
- Pin 15 (VDD): Logic supply voltage (3V–5.5V).
- Pin 16 (ENABLE): Active-low enable pin for driver control.
It supports full/half-step modes and includes built-in protection features like thermal shutdown.
