**V1.2 is in a untested state! Please dont order pcbs until this note vanished**
STM32F072 devboard featuring USB 2.0 full-speed, DFU Bootloader, USB-PD Phy, Arduino nano alike pinout and size.
More documentation and firmware examples will be aviable soon.
## Building and Flashing
### Via Arduino
[You can build and flash the firmware via Arduino as described here.](https://github.com/stm32duino/Arduino_Core_STM32)
## Via Makefile and DFU
Or you can generate a basic firmware with HAL init and Makefile with CubeMX. The binary can then be build with make flashed with dfu-utils.
$ make
$ dfu-util -a 0 -s 0x08000000:leave -D build/firmware.bin
