AUAV-X1 , a new vision of the PX4 autopilot


Arsov RC Technology is proud to introduce a new vision of the PX4 v2 Autopilot board. The Arsov AUAV X1 is another elegant design from Phillip Kocmoud and Nick Arsov. Our goal was to product a high quality, compact, lightweight and cost effective alternative to the PX4 V2 or PixHawk autopilots. This is our first attempt to join the PX4 community after developing several successful designs for the MatrixPilot community. After we have finalized the design we will release the design files and schematics. The schematics will be released immediately to new owners. Initial supplies are limited and a deposit insures a boards in the first production run.

New power supply based on TPS63061 DC-DC Buck-Boost
The TPS63061 device provides a power supply solution for products powered by either three-cell up to six-cell alkaline, NiCd or NiMH battery, or a one-cell or dual-cell Li-Ion or Li-polymer battery. Output currents can go as high as 2A while using a dual-cell Li-Ion or Li-Polymer Battery, and discharge it down to 5V or lower. So you can connect a 2 cell Li-Po directly to the AUAV X1, and run it completely flat before brownout. Since it's a buck-boost converter, you can also power from a 5V BEC while still in regulation. Additional info about this Buck-Boost regulator could be found here -

4 x UARTs - 3 of them have Vcc, Tx, Rx, GND and one has a full set - Vcc, Tx, Rx, RTS, CTS, GND
1 x CAN with MAX3051
1 x I2C
1 x SPI
2 x ADC + 2 x ADC for current and voltage sensing
8 x PWM Receiver Inputs
8 x PWM Servo Outputs
2 x JTAG connection specifically for the TC2030-CTX-NL 6-Pin cable
micro SD card holder
micro USB connector
All inputs and outputs are ESD and EMI protected

30mm x 43mm

    Bump, anyone know how to connect an analog airspeed sensor to the X1?

  • Moderator

    Old thread but still want to use my X1.

    How does one connect an analog airspeed sensor to the X1? There are pins for it on the X2 but what does one do for the X1?

  • Moderator

    No worries, my X2 is on it's way but not here yet.

  • Just wanted to make sure, because the posts before you were dealing with X2 ;-). The X2 doesn´t (normally) need to be set to 8 @ AHRS_ORIENT and COMPASS_ORIENT2

  • Moderator

    No, talking about the X1, (this is the X1 thread :)). SD card at the bottom and LEDs up. From Nick Arsov: "Yes, our X1 needs Roll 180 if you want it with LEDs upside"

  • Graham,are u talking of the X-2 ? If so, I guess, you mounted the X2 upside down. SD-Slot is located @ the bottom.

    AHRS_ORIENTATION has to be set to 8 (Roll180) on this board, it seems that COMPASS_ORIENT2 has to also be set to 8 (Roll180). I kept getting Error Compass Variance with ACv3.3rc10 until I changed that.

    LOKI v2(Locate, Observe, Krack, Isolate) The Kali Linux Drone with AUAV X2

    Track radio collars through RFID, Bluetooth, GSM, or Wifi for Wildlife Conservation.  This is version 2.  It is almost done.  The first version was mostly a mockup with all the control in place but none of the embedded systems.  The AUAV X2 was straightforward for setup, installation and flight.

  • Hi Steven,

    X2 has 3 row 2.54mm right angled ( straight on request ) headers on front and rear sides ( ) and 6 x 1mm pitch two side connectors for telemetry and SPI.

  • What connectors are used on the X2? For example, DF-13 or Molex picoblade?
