+OtterPill is a 3$ STM32F072 devboard featuring USB 2.0 full-speed, a DFU Bootloader, a USB-PD Phy and Arduino nano alike pinout and size.
-HW v1.1 is finished and tested, v1.2 will be finished and tested soon. New features/changelog: BOM cost reduction by ~40%, PCB can be fully populated by JLCSMT, more efficient buck converter (PCB gets less warm at 20V), GND-hook for probing, Reset-Pin will be exposed as pad, power pads for 20V/5A

More documentation and firmware examples will be aviable soon (including pinout diagram).
