1-Wire Plug is 1-Wire to i2c bus converter board based on Maxim DS2482-100 Single-Channel 1-Wire Bus Master chip. It is used to off-load the time critical 1-Wire waveform generation from the MCU to the 1-Wire Bus Master to achieve error free operation with longer 1-Wire bus situations. Board header layout is compatible with TaaraNode and JeeNode microcontroller boards. There is on-board 5V LDO regulator, strong pull-up mosfet and the level converter for 5V to 3.3V i2c interface.
