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.
Connect sensors from the LDCCOILEVM with unshielded twisted pair wires to J6 of the LDC2114 EVM.
NOTE:
Schematics, Layout, and Coil characteristics of the
are described in the
LDCCOILEVM
shows the connection options for each coil type.

NOTE:
When connecting the coil board to the EVM, it is recommended to attach the assembly to a
static object using tape or screws. This will prevent the cables from moving and potentially
changing the output code reading or reporting false triggers.
