SNAU163C August 2014 – October 2016 FDC1004
J1, J2: 4x1 Header: the I/O ports of sections between the USBtoI2C and the FDC1004 sections. This provides the I2C communication channel and the power connections between these two sections should the EVM be separated into sections. A simple 4 wire cable can be used to interface the sections.
J3: USB interface to connect the EVM to a PC; it also provides power to the EVM.
J4: 10x1 Headers. This is not populated by default. It provides an easy method to change sensors or to remotely place the sensor away from the FDC1004. This connector with its counterpart, J5, allows the communication of the two modules through a 10-wire cable.
J5: 10x1 Header, for the electrical connection between the FDC1004 and the sensor section.
