README
README.mdDraco
Draco is opensource HW&SW UAV flight controller board. It was primary designed for my needs, but anybody can manufacture it, use it or modify it. If you would like to own one, you can contact me.
It has two MCUs on it. The smaller one is used for OSD. The bigger one is running TauLabs flight code.
###Features###
- main MCU STM32F4, MCU for OSD STM32F303CC
- 32MBit serial flash
- MPU9250 in SPI mode
- MS5611 in SPI mode
- CAN bus transceiver
- microSD slot via SDIO
- 4x A/D inputs
- slot for telemetry module (XBee or PirateBee)
- half-duplex inverted serial line for new FrSky S.PORT telemetry bus
- GPS port with power, UART and I2C for external compass
- 2x extension port with UART/I2C and GPIOs
- extension SPI port
- dedicated sonar port with power and trigger+echo signals
- microUSB
- 12x PWM in/out + 1x S.BUS/CPPM pin on 2.54mm header
- 6x LEDs
- micro button
- OSD with resolution 320x240, automatic PAL/NTSC detection
- dimmensions: 62x47mm
###TauLabs### Draco is currently one of the non-official TauLabs target. You can find ported code at my fork. There are still some things missing and I will probably add them in short time:
-
support for microSD card logging
-
support of FrSky S.PORT telemetry protocol
-
micro button support

Questions
How big is the Draco PCB?
It measures 47.5 × 62 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Draco use?
164 parts, built around the STM32F303CCT6, STM32F405VGT6, SN65HVD233D and EL1883IS. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Draco KiCad files?
From the xdandys/draco repository on GitHub, at the commit this page was made from: the board is hw/export/rev0.9/eurocircuits/draco.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Draco design in my own project?
Its repository states no licence, so its author keeps all rights: ask xdandys before reusing the design.
