This is a very small IR receiver based on the TSOP85 receiver from Vishay. This receiver has all the filtering and 38kHz demodulation built into the unit. Simply point a IR remote at the receiver, hit a button, and you'll see a stream of 1s and 0s out of the data pin.
This board does not come with a header installed. The photo will be updated soon. Please see related items below for connector options.
