MSP-EXP430FR2433: How to make a custom board

Hello, 

I wrote firmware required for my application on the dev board for the micro. The dev board has too much stuff for my application. I need to make my own custom board which will be much smaller. I only need two components from the dev board. The micro and the USB connector. The links are below:

I do see that the PC to the micro interface is via UART0. But how do I make the connections? Do I use the following connector:

I did find the schematic for the above component. I can incorporate it into my custom board. But is there a simpler way?

Thank you

    Hello,

    The LaunchPad design files are a great start and can be used to trim down based on your needs.

    Another good design reference that we recommend is the MSP-TS430RGE24A target socket board for the MSP430FR2433 device. It includes the most important components including passives, JTAG connections, etc. for proper programming, power-up and operation. While the PCB design files aren't available, you can find the schematic for the socket board in the MSP430 Hardware Tools User's Guide.

    If you need the UART communication only during development, then you could just use some UART RX/TX headers on your board and connect those pins to a USB-to-serial adapter. You'll also need to program the MSP430FR2433 on your board, so you'll want to add headers or a connector for that. You can use the MSP-FET or the eZ-FET debugger on-board the MSP-EXP430FR2433.

    At the top of the MSP-EXP430G2ET LaunchPad, you'll notice a small programming footprint, J100, for Tag-Connect cables that could be used in your design.
