I am in a project group and we’re using Electron with an Arduino Nano. Everything worked but when we got a motherboard and soldered everything on, the Electron now has dimmed blue D7 led.
I am trying to figure out what it means, but every post I come over says there’s no other light, but we got a red light from power. (?)
I am not able to get my hands on it now, but I will soon be able to test. I just wonder what it means? Is it bad soldering? We only use an external LED to show that the Electron is connected to cloud and tx/rx serial. We have switches for RX/TX otherwise microcontrollers have problems booting.
I got pictures of this when I am away. That’s why I can’t do anything else than Google and ask here for assistance.
