Raspberry Pi 3 Model A+
Best compact controller for space constrained DIY electronics projects.
This is the perfect choice for minimalist builds where space is at a premium but processing power remains non-negotiable. By stripping away the Ethernet port and extra USB slots, it delivers a streamlined, compact footprint without sacrificing the essential GPIO compatibility needed for serious hardware projects.
