I2C Communication connector KIT34704AEPEVBE 8-Channel Evaluation Board, Rev. 1 Freescale Semiconductor 11 KIT34704AEPEVBE - Using Hardware 8.2 Input/Output power supply terminal blocks A three-pin terminal block serves as the input terminal for the main power between 2.7 and 5.5V to operate the KIT34704AEPEVBE, as well as providing access to the reference voltage VDDI generated by the MC34704A to supply configuration voltages. Regulator 1 uses a three-pin terminal block to provide GND reference and VO1 output at 5V with a maximum current capability of 500mA. It also provide access to the internal Gate voltage VG for monitoring purposes Regulator 2 through 8 use a two-pin terminal block to provide each GND reference and VOx respectively. To learn how to configure the output voltage on each regulator, please refer to the MC34704 datasheet that can be found at www.freescale.com The following diagram shows each of the terminals and its respective output voltage identificator.

Input/Output terminal blocks 8.3 Starting up the KIT34704AEPEVBE To Start working with the KIT34704AEPEVBE, provide an input voltage between 2.7V and 5.5V connecting the (+) probe to the VIN terminal and the (-) probe to the GDN terminal on the Input power terminal block. Turn on the power supply and the LEDRST should turn on. At this moment the three stand alone regulators (REG2, REG3 and REG4) should be providing pre-configured output voltage. To operate the rest of the MC34704A functions, it is necessary to use I2C communication.
