💡 What is a 3V/3.3V relay module with optocoupler isolation used for in DIY electronics?
It's handy for safely switching higher-power loads from a low-voltage controller while protecting the control circuitry.
- Optocoupler isolation provides electrical separation between control and load circuits.
- 3V/3.3V drive works with common MCU families without extra level shifting.
- 10A load rating covers typical home automation and hobby projects.
- Jumper options let you decide whether to share a power supply or isolate it.
