This week we had the idea of making a breakout for IrDA data transfer: this is an older infrared bi-directional protocol that can mimics UART-like behavior with RX and TX running at 115.2Kbps.

It could be useful for projects where you want to make a link between two boards but don't want the expect, complexity or overhead over RF. Simply transmit and receive whenever the two are within about a meter of distance.

This used to be used for simple data transfer between computers, handhelds, or watches. They've phased out of popularity in the last couple decades... can we still get IrDA transceivers at DigiKey? Let's find out!
