ELM339 Description
The ELM339 is a plete remote control decoder in an 8 pin package. With the addition of a standard infrared receiver module, three individual outputs can be simultaneously controlled using a television remote control transmitter. This circuit responds to Sony™ television control codes, chosen because most universal remotes default to them when initially powered up.
