Hello today I wanted share quick summary specification of current controller board design,

and as this project is meant to be opensource I want to share some sources today I Think both will be good summary for entry round of this contest :).

Controller software:

https://github.com/krzysztofkrzeslak/pixpi-controller-app

it's Python app sources which is running on controller.

Hardware specification:

1 x Optoisolated camera port(2,5mm jack) for camera focus/wake and trigger

2 x Optoisolated Flash port(3,5mm jack) for flash triggering

3 x module port, which can be used in following modes:

      Port Red: Input, Output, Com(1-wire), Pulse

      Port Green: Input, Output, Pulse

      Port Blue: Input, Output, Pulse

      Each port has 3 pins: Signal, 12V, Gnd

      Ports connector fits standard servo connectors

8 x Gpio pins

1 x mini-B usb connector for accessing Linux command line/serial console.

1 x 1,27mm 6pin SPI connection for complete flash writing(unbricking, bootloader change, etc. )

1 x DC jack for 12v supply (should be tolerant up to 22v)

2 x status led: supply, ready

3 x port status led

1 x Buzzer for state indication

Powered with opensource VoCore2 system on module (https://vocore.io)

Which provides:

- Mediatek MT7628, 580 MHz SoC

- Memory(ram): 128MB, DDR2

-  Flash: 16MB

- Running under Linux(OpenWrt) control.

It's also fully OpenSource: Complete specifications and sources available on: https://vocore.io/v2.html
