Hi guys,

I was looking at the electrical schematic of Esplora and noticed there is three light sensors. But looking at Esplora image I saw only one LDR mounted on the board.



Could someone explain to me why there are three sensors in the electrical schematic?

best regards

I received my board and noticed that there is different pads for mounting a LDR or a phototransistor.
