Breakout for TI’s 16 bit RISC chip MSP430FR2111. This breakout includes a power LED, a status LED connected to P2.0, reset button, 3V3 regulator, and pinout for plugging directly into the MSP-EXP430FR2311 for development and uploading.
Why
I wanted to start programming for the MSP430 series, and get a more tangible sense of the capabilities and pitfalls of these chips. I went looking around LCSC for cheap but somewhat capable chips in the series, and stumbled upon the MSP430FR2111. It was one of the cheaper MSP430 chips in stock at LCSC at the time. I have nothing against programming and developing with the expansion board, and it certainly a lot cheaper and easier to get up and running. However, developing a breakout board, for me helps to force me into reading the datasheet and really trying to better understand the architecture. And if I don’t fumble things too badly, I’ll have a leg up on any future development. And thankfully, the first version of the board came out functional. I could program the board through the MSP-EXP430FR2311 board, and was able to make the onboard LED blink.
Additional
I do have a GitHub repo with the KiCad project and gerber files, should anyone be interested. I’ll probably add some test code, eventually, demonstrating some basic functionality that I was able to program with this chip. Although there are certainly fair better sources for that material, than anything I can come up with.
