Texas Instruments has introduced the MSPM0C1104, which it describes as the world's smallest microcontroller, expanding its MSPM0 MCU portfolio. Measuring only 1.38mm², this wafer chip-scale package MCU is 38% smaller than existing alternatives. It is designed for applications where board space is limited, such as medical wearables and personal electronics, while maintaining functionality. The MSPM0C1104 includes a 24MHz Arm Cortex-M0+…
That looks like a real pain in the ass to solder with a 0.35mm pin pitch.
Not something I would try to hand-solder. Not something that feels relevant for me as a hobbyist either, although it’s very cool.
Imagine the arduino-clone boards with these… For very small hands!
