A wiring question is faster to answer with a photo than a phone call. Send the board, the supply, the load, and the controller — we open the schematic and reply.
Online support lets us review photos, wiring details, and the schematic so we can provide an accurate answer.
What to include
- Board name or SKU — PWR INTF, OUT-4, or IN-4
- Supply voltage
- Controller — Arduino, ESP32, Raspberry Pi, or similar
- Load or sensor type
- What it does vs what you expected
- Photos, a diagram, or a short wiring note
Before you write
The current manual often already has the diagram. Open yours first.
