DEV-SOMRT1061 Development Board

The NNDK-SOMRT1061-KIT includes a DEV-SOMRT1061 development board with a SOMRT1061-200IR SOM soldered onto a small CAR-SOMRT1061 carrier board. The carrier board enables you to remove or replace the SOMRT1061 SOM on the development board. The information in this section details the connectors, jumpers and headers on the development board as well as suggestions for use.

A typical configuration is:

USB for power and serial communication. The serial port provides status messages as the system runs, and can be used for your application status messages as well. The default microprocessor serial port is LPUART3. Alternatively, you can adjust the jumpers and use the RS-232 DB9 port J13. The boot LPUART is selectable though the configuration screen of the SOM.
The input power range is 5V to 24V.
J1-J4 and P1-P4 are the same SOMRT1061 signals. The headers are provided for ease of use during development.
Ethernet 0 utilizes the Ethernet PHY on the SOMRT1061-200IR. Ethernet 1 requires an external PHY, which is located on the DEV-SOMRT1061.
