UNBRK is a 3.2x3.2cm QFP48/64/100/144 breakout board with a VCC bus on all four edges of the topside of the board and a GND bus on all four edges on the bottom of the board. The buses have been placed adjacent to the breakout pads to simplify the process of powering the MCU and the placement of decoupling capacitors where this might be necessary. Due to the board being as small as it is, we've added ruler lines to the breakout pads on the top of the board to ease finding the correct pin numbers when using the pinout diagrams on this page. The remaining area on the bottom of the UNBRK functions as a prototyping area for 0201-sized surface-mount components. The aim of the project is to allow rapid prototyping with MCUs by using components salvaged from discarded mobile phones. Full documentation is currently under development.
UNBRK is a compact breakout board (3.2x3.2cm) that supports QFP packages of 48, 64, 100, or 144 pins.
### Features:
- Compact form factor - 3.2x3.2cm board 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 four edges of the top side.
- GND bus runs along all four 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.
- Salvage-friendly design - Enables rapid MCU prototyping using components reclaimed from discarded mobile devices.
