1. Relays & Switching Modules
Relays let your microcontroller control high-power devices safely — from household appliances to industrial machinery.
Solid State Relays (SSR)
The SSR-25DA (25A) and SSR-40DA (40A) are optocoupler-isolated AC load switches with zero-crossing switching for minimal electrical noise. No moving parts means silent operation and long life. Ideal for heating element control, lighting systems, and industrial automation where silent, reliable switching matters.
Electromechanical Relay Modules
The 1-channel relay modules (5V and 12V variants) are the standard choice for most microcontroller projects. Each module includes optocoupler isolation, a flyback diode, and an LED indicator. Available in 4-packs for multi-channel control.
Timer Relay Modules
Programmable timer relays with Type-C connectivity and cyclic trigger modes. Perfect for delayed start/stop applications, interval timers for irrigation, and automated lighting schedules. The 6-30V wide input range makes them compatible with most systems.
2. Voltage Regulation
Converting voltages efficiently is critical for battery-powered and multi-voltage projects.
MP1584EN Step-Down Module
A compact DC-DC buck converter that steps down voltages from up to 28V to as low as 0.8V with up to 3A output. High efficiency (over 90%) means minimal heat generation. Available in 6-packs for multi-rail designs.
