VS1838B IR Receiver
The VS1838B is a PIN photodiode high-gain amplifier IC in an epoxy package with an
outer shield. It consists of three pins and is about the size of a signal transistor. This
inexpensive part can be purchased for about $2 on eBay to give your Raspberry Pi the
ability to read many IR remote-control signals.
