From the project
Allwinner V3s prototype SBC
- Changed the Ethernet port , also this time it is right side - Changed power supply of Serial to USB chip for the board own power, no accidental pull down now - USB ports are more on board - Heartbeat led added on PF6 - battery pins are bigger, JST model - Added port for +5V - UART serial port is now near serial usb - Added func button - Pull-up for i2c - Added leds for CPU and Memory activity, through shift register

OzzyBoard: common questions
What microcontroller does the OzzyBoard use?
The OzzyBoard is built around the STM32, from the STM32 family.
How big is the OzzyBoard PCB?
The OzzyBoard measures 100 × 100 mm, has 4 copper layers and is 4.69 mm thick.
How many components are on the OzzyBoard?
278 components, from 92 distinct parts. The full bill of materials is listed on this page.
Where can I download the OzzyBoard design files?
From the vbalsan/OzzyBoard repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the OzzyBoard design in my own project?
Yes, under the terms of its GPL-2.0 license, which vbalsan chose for the repository.
Can I test firmware for the OzzyBoard without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
