Embedded AC Dimmer Module for Custom Electronics Integration
The RBDimmer 16A Embedded Module is a solderable AC dimmer designed specifically for integration into custom PCBs and electronic products. Unlike standard dimmer modules with screw terminals, this embedded version features clean solder pads that mount directly to your circuit board – perfect for OEM applications, product development, and permanent installations.
Designed for Professional Integration
This module eliminates bulky terminal blocks in favor of optimized solder connections. Control signals (PWM input, zero-cross output, VCC, GND) use industry-standard 0.1" (2.54mm) pin spacing – compatible with standard headers, breadboards, and PCB layouts. High-current load connections use wider 0.2" (5.08mm) spacing to accommodate heavier gauge wires and ensure reliable power delivery at full 16A capacity.
Powerful and Versatile
With 16A current handling at up to 600V AC, this module supports a wide range of resistive and inductive loads: dimmable lighting, heating elements, fans, pumps, and motor speed control. Phase-angle control provides smooth, flicker-free dimming across the entire range – not simple on/off switching.
omplete Electrical Isolation
The optocoupler-isolated design completely separates the high-voltage AC section from your low-voltage microcontroller circuit. This protects your control electronics and ensures safe, reliable operation in any application.
Software Ecosystem
Full compatibility with the rbdimmerESP32 library for Arduino and ESP-IDF frameworks. Ready for ESPHome external component integration and Tasmota firmware. Build smart home devices with Home Assistant connectivity, or develop standalone products with custom firmware.

Applications:
- Custom smart home devices and wall dimmers
- Industrial control panels and automation systems
- OEM lighting and HVAC products
- Laboratory and test equipment
- IoT devices requiring AC load control
