How do I power Wemos D1 Mini Properly? - Project Guidance - Arduino Forum
Hi, I am creating a project using Wemos D1 Mini to control a two-relay module. If I supply power to Wemos using USB and relays using a buck converter (all 5v) then everything seems to be working. However, if I power everything from just the buch converter, nothing works. I have tried to explain this using diagrams. Please let me know what I am doing wrong. Thanks. This setup does not work.
