Sensors & Modules for Robotics, IoT & Automation

The DC 12V 4-Channel Relay Module is a compact relay interface board designed to control multiple AC or DC loads using Arduino, PIC, AVR, ARM, DSP, PLC, and other microcontrollers. It features 4 optocoupler-isolated channels, low-level trigger inputs, and individual relay status LEDs for easy monitoring. Each relay supports up to 250V AC/10A or 30V DC/10A, making it suitable for home automation, industrial control, lighting, motors, pumps, and DIY electronics projects.

The ADS1115 16-Bit Precision ADC Module is a high-resolution analog-to-digital converter designed for accurate sensor and analog signal measurement. It provides four single-ended or two differential input channels, supports a wide 2.0V–5.5V supply range, and offers programmable data rates from 8 SPS to 860 SPS. With an integrated PGA, internal voltage reference, oscillator, and I²C interface, it is ideal for Arduino, ESP32, Raspberry Pi, robotics, IoT, and precision data-acquisition projects. PCB colour may be blue or purple and will be supplied randomly; images are for representation only.

MX1919 Based Motor Driver Module is a compact dual H-bridge controller supporting up to 2.5A peak current, 2–10V DC operation, and 1.8V/3.3V/5V logic compatibility. It can control two DC motors or one 4-wire stepper motor, making it ideal for Arduino, ESP32, Raspberry Pi, micro-mouse, line-following, robotic, and DIY projects.
