Ardupilot/PX4 communities : DIY hardware Innovation is still alive and well - the new XRacer V1.0

AUAV is proud to announce our latest high quality PixHawk derivative - The XRacer V1. This project was developed in cooperation with Lorenz Meier, David Sidrane, Leonard Hall and many others. This board combines the latest IMU offerings from InvenSense and a large number of capabilities in a micro 36mmx36mm form factor.


Below are some pictures to peak your interest.


XRacer V1 specifications:

  • MCU - STM32F427VIT6 rev.3
  • FRAM - FM25V02-G
  • Ultra low noise LDOs for sensors and FMU
  • Sensors used - MPU9250, HMC5983 ( optional ), ICM20608 ( optional ), baro MS5611
  • Connectors - GPS+I2C, RC-IN, PPM-IN, RSSI, SBus-IN, Spektrum-IN, USART3 ( TxD, RxD, CTS, RTS ), USART2 ( TxD, RxD, CTS, RTS ), FRSky-IN, FRSky-OUT, CAN, USART8 ( TxD, RxD ), ESP8266 ( full set ),      SERVO1-SERVO6, USART7 ( TxD, RxD ), JTAG ( SWDIO, SWCLK ), POWER-BRICK ( VDD, Voltage, Current, GND ), BUZZER-LED_BUTTON
  • MicroSD card reader
  • Micro USB
  • ESP8266 802.11bgn ( optional )
  • Dimensions - 36 x 36mm with 30.5 x 30.5mm hole grid with 3.2mm holes
  • Molex Clik-Mate ( JST GH series ) connectors for easy peripheral connect.
  • Full set of ready made cables for almost any peripheral module.
  • Power supply - 5-5.5VDC from USB or PowerBrick connector. Soon the  ACSP4 ( 36 x 36mm power distribution, current, voltage sensor with 5V/2.5A ultra low noise buck and 12V/2A ultra low noise buck ) companion will be announced.


The price and availability will be announced within a few weeks.


Thank you again for your support.

Awesome. I'll take one!

Very nice and really small. Please what about barometer ? I am correct it's on the blue add-on module ?

Comment by Nick Arsov on November 3, 2015 at 9:07am

Hi Paul,

The barometer ( MS5611 ) is on the bottom side...close to the microSD card socket.

The Blue module is an optional (ESP8266) WIFI module, With the goal of removing the USB tether.

Wow. This looks great and truly innovative. I am not an FPV racer myself but small is always better.

Hi Marc,

The XRacer is just its name, but the controller can be used for any copter, fixed wing or rover project.

Hi Nick,

another great piece of hardware again !

Just one question: Is this board fully Pixhawk compatible ?

I'll just ask because it seems the second microcontroller (STM32F100C8T6) is missing ...

Comment by Nick Arsov on November 3, 2015 at 10:02am

I think the firmware gurus will make their best to make it Pixhawk compatible. More, that was the idea ;-)

Comment by Nick Arsov on November 3, 2015 at 10:04am

Forgot to mention that the FMU connections are very very similar to PX4 ( with a few exceptions ).

Comment by Phillip Kocmoud on November 3, 2015 at 10:24am

We do have developer assurances that it both Ardupilot and PX4 will support this board.
