The DRV8825 is a high-performance microstepping motor driver module built around the Texas Instruments DRV8825 IC that controls bipolar stepper motors using just two signals — STEP and DIR — from a microcontroller. By handling all phase sequencing, PWM current regulation, and microstepping waveform generation internally, it drives a stepper motor smoothly and precisely without … Read more
The A4988 is a complete microstepping motor driver module built around the Allegro A4988 DMOS microstepping driver IC with built-in translator. By accepting just two control signals — STEP and DIR — from a microcontroller, it independently handles all the phase sequencing, current regulation, and microstepping waveform generation required to drive a bipolar stepper motor … Read more
The L293D motor driver module is a compact breakout board built around the L293D quad push-pull motor driver IC that controls the speed and direction of two DC motors or one bipolar stepper motor simultaneously. By accepting standard TTL logic level signals from a microcontroller and switching motor power independently through two internal H-bridge circuits, … Read more
The L298N is a high-voltage, high-current dual full-bridge motor driver IC manufactured by STMicroelectronics that controls the speed and direction of two DC motors or one bipolar stepper motor simultaneously. By accepting standard TTL logic level signals from a microcontroller and switching high-current motor power independently, it acts as the bridge between low-power control signals … Read more
The rain sensor module is a two-part resistive detection system that senses the presence and intensity of rainfall by measuring the change in electrical conductivity across a set of interleaved nickel-plated copper traces on an exposed sensing board. As raindrops bridge the traces, resistance drops and the analog output voltage changes proportionally — the wetter … Read more
The LattePanda V1 is a unique single-board computer that blends two worlds on one PCB: a full Windows PC and an Arduino-compatible microcontroller.
