2.2 Header Information

An eight pin header (J7) is provided as a means to monitor the various connections to the ADS121M08. This header allows access to the modulator clock, SDI, SDO, SCLK, DRDY, CS and the SYNC/RESET input.

J9 is a 5-pin dual row header that allows users to use the TIDA-010986 reference design with the ADS131M08MET-EVM. This reference design implements a hardware integration scheme for use with PCB based Rogowski coils. More details are found in the TIDA-010986 design guide.

J10 is a 5-pin two row JTAG header that allows further customization of the firmware that is loaded into the MSPM0G1506. Further details and access to the CCS project used for the ADS131M08MET-EVM is found in the MSPM0-SDK documentation.
