Recently, I bought a Rachio 3 sprinkler system. Living overseas, I have a common voltage of 220 volts, as opposed to the 110 volts the Rachio 3’s transformer was designed for. When testing the Rachio, I overlooked this fact, and smoke came out of the power-in port. I had it plugged in for about 3 seconds, but the damage was done. In the aftermath and after examining the circuit board, I was thankful to notice there were only 2 parts “fried”/“burnt”: the power-in port (an easy fix) and a component with “100 B1E.” written on it. This component I could not find online, and I was hoping to find help here. Below, I will attach an image of the board and highlighted said component. Any and all help will be appreciated!
P.S. I have a moderate understanding and what I consider to be a decent skill at soldering, so any and all suggestions are welcome.
