Review on ⚡ DGZZI 2PCS 12V DC-DC Voltage Converter Multi-Output Step-Down Power Supply Module for Arduino - Efficient Conversion for Various Voltage Levels by Devin Jirsa
NO HOLES. Contrary to the description
Three points: 1) "Two pinholes are specially designed to be fixed directly on the pinboard for expansion experiments; circuit board for any purpose including interconnection2) Ground ( connected in common) including power3) Switch ONLY cuts power to board components. Power ALWAYS stays in 3rd position. You must provide an external switch for power.
- Great for a small house
- Questionable purchase for the elderly
