Page 6: Overview
LDC is controlled by an MSP430, which interfaces to a host computer. The LDC2112 is the two-channel version of the LDC2114. The LDC2112 does not have a dedicated EVM. Instead, the four-channel LDC2114 EVM should be used to evaluate the technology and performance. -
Page 7: Compatible Sensor Evm
The EVM does not include any example sensors, but can easily be connected to sensors by using either the ZIF connector or soldering wires to the header pins on the PCB. The LDC2114 EVM is compatible with the LDCCOILEVM, which is available on the TI estore and contains 19 different sensor designs. -

10. Perforation and probing header: These pads can be used for probing any signals between the MSP430 and the LDC2114. It can be populated with a standard 2x11 pin 2.54mm header for ease of access. It is also possible to break the LDC along the perforation and attach a different microcontroller to these pins. -
