DimmerLink Goes Multi-Channel: 2CH and 4CH Versions Are Here
When we launched DimmerLink, the idea was simple — take the pain out of TRIAC dimming. One channel, zero flickering, five lines of code. You loved it.
Now we're taking it further.
Introducing DimmerLink 2CH and DimmerLink 4CH — the same Cortex-M+ precision timing, but for multi-channel dimmer setups.
What's New
The 2-channel and 4-channel modules handle all phase-cut timing internally for every channel simultaneously. Your MCU still uses just 2 pins (UART or I2C) to control everything. No extra GPIOs. No multiple hardware timers fighting for CPU time. No flickering — on any channel.
Direct Plug-in to RobotDyn Dimmers
Output pins are laid out to match the RobotDyn 2CH and 4CH TRIAC dimmer headers. You can plug the DimmerLink straight onto the dimmer board, use jumper wires, or connect with a flat cable. Male and female pin headers are included.
Same Simple Protocol
If you already use DimmerLink 1CH — you already know how to use these. Same registers, same commands, same 3-byte simplicity. Each channel gets its own brightness level and dimming curve.
Why This Matters
A 4-channel dimmer without DimmerLink needs 4 GPIO pins, 4 hardware timers running microsecond ISRs, and a prayer that your WiFi stack doesn't glitch the timing. With DimmerLink 4CH — two wires, one command per channel, done.
