STM32 is mostly used for embedded circuit design and development, most notably for industrial robots: ST also offers a line of STM32 learning boards called NUCLEO priced starting at around $30.

An Arduino is by no means expensive, but that still doesn't mean that it suits your needs right out of the box. If you want to make your own custom board, Make shows you how in a three-part series.

The tutorial is intended for those rolling their own boards out of an Arduino-based prototype, but it will work in any situation where you need multiple connections to a single set of UART pins.

They can also ‘flex to fit’, conforming to a curved design. Designers can fold and shape their circuits into complex forms and, for example, create battery contacts, curved sliders, and buttons or LED ...
