What We Do
RBdimmer designs and manufactures AC power control hardware for engineers, makers, and system integrators. Our product line covers phase-angle dimmer modules, intelligent controllers, and development boards — all built around reliable TRIAC-based circuits with full electrical isolation.
We don't make consumer devices. We make components that you integrate into your own projects.
Products
Our current lineup includes:
AC Dimmer Modules — single and multi-channel TRIAC dimmers from 4A to 40A, with 3.3V/5V logic compatibility. Designed for Arduino, ESP32, Raspberry Pi, and virtually any microcontroller with a GPIO output.
DimmerLink Controller — an 18×12mm UART/I2C bridge that offloads all timing-critical dimmer operations to a dedicated Cortex-M+ processor. Eliminates interrupt conflicts in complex projects.
ACRouter — an ESP32-based development board with two AC dimmer outputs, two relay outputs, onboard voltage and current sensing (ZMPT107 + SCT-013), buzzer, LEDs, and broken-out GPIOs. Purpose-built for AC power routing and monitoring projects.
Current Sensors and Accessories — SCT-013 current transformers and adapter boards for power measurement.
Libraries and Firmware
We maintain open-source libraries for all our hardware:
- rbdimmerESP32 — ESP32 dimmer library using hardware timers and GPIO interrupts. Supports Arduino, ESP-IDF, and ESPHome frameworks. Multi-phase compatible.
- ESPHome external component — native integration with Home Assistant via ESPHome configuration.
- Tasmota support — documented configuration for Tasmota-based projects.
All libraries are available on GitHub.
Documentation
We publish technical documentation for every product: hardware connection diagrams, wiring guides, API references, and framework-specific examples. All documentation is available in English, Russian, German, French, Spanish, and Italian.
