The UNBRK HEX is an improved and hexagonal version of the UNBRK breakout board. Like its predecessor, it supports QFP packages of 48, 64, 100, or 144 pins.
### Features:
- Compact form factor suitable for space-constrained, low-power designs.
- Supported QFP packages - Compatible with 48, 64, 100, and 144-pin QFP footprints.
- VCC bus runs along all six edges of the top side.
- GND bus runs along all six edges of the bottom side.
- Buses are positioned adjacent to breakout pads, simplifying MCU power routing and decoupling capacitor placement.
- Ruler markings function as a pin-identification aid, printed adjacent to the top-side pads to mitigate the difficulty of locating pins on a small board.
- Underside reserved as a prototyping zone for 0201 surface-mount components.
- Enables rapid MCU prototyping using components reclaimed from discarded mobile devices.
### Improvements
- **Multi-angle capability**: The design now supports operation at multiple, non-rectilinear angles, which enhances visibility when the board is viewed from various orientations.
- **Wider trace geometry**: Traces have been broadened to reduce resistance and improve low-power performance of microcontrollers, leading to more efficient power consumption.
- **Optional header pins**: The layout includes provisions for adding header pins, facilitating easy connection of external peripherals or test equipment.
- **Enhanced 0201 prototyping grid**: The 0201-size surface-mount prototyping area has been refined, providing a more reliable platform for assembling and testing ultra-small components.
