【Upgraded ULN2003 Alternative】 Powered by SA8302 chip with MOSFET architecture (PMOS+NMOS), offering significantly lower heat generation and higher efficiency than traditional Darlington-based ULN2003 drivers. Ultra-low on-resistance (400mΩ).
【Versatile Dual-Mode Drive】 A true 2-in-1 solution. Supports driving 1x 4-phase 5-wire stepper motor (like 28BYJ-48) or 2x Brushed DC motors with full Forward, Reverse, Stop, and Brake functionality.
【Powerful yet Efficient】 Supports a wide working voltage of 2V-7V. Delivers a continuous current of 1A per channel with a 3A peak, making it ideal for DIY robotics, smart locks, and small pump projects.
【Ultra-Low Power Consumption】 Features an incredibly low standby current of only 0.1µA, perfect for battery-powered applications where energy saving is critical.
【Integrated Protection & Easy Setup】 Built-in Over-temperature Protection (OTP) and Under-voltage Lockout (UVLO) for circuit safety. Pre-equipped with XH2.54 and PH2.0 interfaces for plug-and-play connectivity with Arduino and ESP32.
