Story

I was very curios on this extremely small 32 ARM MCU from Texas Instruments the MSPM0C1104S8YCJR. I decided to try and make my own small evalboard with breakout pins for measurements and a QWIIC connector + power circuit.<br>I soldered the MCU on to several boards and it worked like a charm. Incredible that its possible to solder this tiny part on to a PCB with simple tools at home.<br>Have a look on the project in the video below<br>">
