openstm32hw README
The aim is to provide Open Source hardware designs for STM32.
This repository grew from a discussion thread on LeafLabs Maple forum:
http://forums.leaflabs.com/topic.php?id=1303
It was initially triggered by ala42 who had released a first cut at libmaple for STM32F4:
http://forums.leaflabs.com/topic.php?id=1268&page=2#post-7828
and siy's hardware design:

Subdirs:
MM4 - Leaf Labs Maple Mini clone for 64 pin F1/L1/F4 processors
in 0.8" width and 2 layers.
Mini64 - STM32 development board for OpenSTM32
Features:
- Small (52x38.4mm) breadboard compatible design.
- Support for STM32F103/F2xx/F4xx in 64-pin packages.
- Uses Eagle 5.1
Mini48 - Reworked version of Maple Mini suitable for DIY PCB production
and on-board RTC crystal. Uses Eagle 5.1
PiXe-2: 'Stamp' format, 64pin STM32F103 MCU. Eagle 5.1
Features:
- Dual-in-line 0.1" grid
- 0805 or larger parts -> easier assembly
- Internal Maple pins available & re-configurable
- modest 10mil track/space rules DIY-able
