ESP8266 Community Forum

- Sun Feb 04, 2018 1:34 am #73686 Basically i'm trying to do this project (https://www.hackster.io/simpleiothings/ ... q-d-f4e1ca) with these boards (https://www.amazon.com/gp/aw/d/B01IK9GE ... _pop_mb_pd). I used ESP8266Flasher and flashed one of the boards and got it doing what I wanted pretty quickly. Now when I try to do the exact same thing on the other board, it isn't working. the first board only had the LED light up for a second when i plugged it in and then it went out, but i flashed it no problem. the problem board is keeping its LED on. when i try to flash it the flasher stays a thing "ready" and in the log it says it's bad looking for the ESP8266 even though i have the right COM port selected and everything's the same as the last board. i've tried different USB cables and reinstalling the driver but i don't know what to do, why won't it let me flash it!?

Hi hortplus,

What kind of power supply solved your problem?
Thank you in advance.
