Review on π MakerFocus Raspberry Pi Expansion Board: 4-Channel Relay Module for Raspberry Pi 4B/3B+/3B/2B - No Programming or Programmable Options by Jim Plump
Works (but not the first time)
Would have been 5 stars but the first one broke. Got a refund/replacement and it works like a charm! It now works to (hopefully) keep my plants alive as part of an automated plant watering system with soil saturation sensors. 3 different I2C caps work without interference. I like it.
- Acceptable
- There are problems
