I connect gnd>gnd, 5v>5v and d1>d1 - nothing works with relay blink code. I change connection to d5 on wemos (still d1 on relay) and it works fine with code change to d5. Any ideas, as at present I can't stack the relay on the wemos? (because the d1 goes to d1) According to pinout, D1 is "I/O, in the default mode, SCL of I2C" and GPIO5. Thanks Hello, I'm trying to program a ESP32 Cam, but since I don't have a FTDI, I'm trying to use a WesMos D1 Mini as a bridge. I saw in this article that this is possible with a NodeMcu since the CHIP_EN is exposed. That's not the case with the D1 Mini though, so I was wondering if there's still a way to disable the chip when uploading code. My Wemos D1 Mini and Mini-lite-based controllers are losing Wifi connectivity after a few hours. Sometimes, they come back online quickly, sometimes it takes hours or even a reset. Are these boards known to be flaky as R… 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 WeMos D1 Mini: Video dell’assemblaggio. You can find WeMos D1 mini on WeMos D1 mini - NodeMCU V2 V2.1 V3 - esp01 - esp01 programmer. You can find 3v realay on XePr.
