It is now cheap and simple to design circuit boards for microcontrollers. Development host systems are also cheap, especially when using [[Open-source software|open source]] software. Higher level programming languages [[Abstraction (computer science)|abstract]] details of the hardware, making differences between specific processors less obvious to the application programmer. Rewritable flash memory has replaced slow programming cycles, at least during program development. Accordingly, almost all development now is based on cross-compilation from personal computers and programs are downloaded to the controller board through a serial-like interface, usually appearing to the host as a USB device.
 
The original market demand for a simplified board implementation is no longer as relevant for microcontrollers. Single-board microcontrollers are still important, but have shifted their focus to:
