I'm using a Teensy for controlling LED strips among many tasks. The strips have parasitic voltages even with the lights off due to each led having it's own control chip. I plan to install relays, probably solid state to turn the strips off when they are really off (Off grid). But I don't want to use to use pins from the Teensy for something so slow. I'm rather offload it to a control board through SPI, I2C, or rs485.
The relays will be different sizes. Some strings are 40amps while others are less than 5. I'd also like to switch some AC on and off too eventually. So I'll be mixing and matching relays.
I have seen relay boards online but they already have low power mechanical relays onboard. Any control boards without embedded relays? Possibly with selectable control voltage?
Thanks
