Interested in getting one of the smallest, low-cost, high-power miniature
IMU/Autopilots or a Linux onboard computer baseboard? Then please read on, it only
takes about 5 minutes. If you participate, you can influence the design of our autopilot
hardware and make sure it suits your needs.
We're currently getting
the pxIMU: Autopilot and IMU [ http://pixhawk.ethz.ch/electronics/imu ] ready for
the MAV community, but before we make the hardware available, we'd like to hear
from the community where we could improve.
This page consists of five short
A summary on pxIMU
A summary on additional electronics that might be relevant for you (e.g.
Linux onboard computer boards)
An example for a fixed wing setup (and the difference to a quadrotor setup)

pxIMU Autopilot and Inertial Measurement Unit Board
Please watch this short video for a quick overview of the unit. Please note
that the autonomous flight in the video requires not only the IMU, but also an onboard
processing unit like the pxCOMEx and at least one camera. GPS based or manual flight
is of course possible using just the IMU.

pxIMU Autopilot Details
[ http://pixhawk.ethz.ch/electronics/imu ]
60 MHz ARM7, 32 KB RAM, 512 KB Flash
State observer attitude / Kalman position fusion filters in floating point
Production costs (machine assembly, low quantities): ~ USD 350-430 The
more people are interested in the unit, the cheaper we can arrange the first
production batch. In case of really strong interest it could get even much cheaper
than USD 350.
pxPower: Power Supply Board [ http://pixhawk.ethz.ch/electronics/power ]
(high-output power supply for pxOvero, video cameras, etc.)
pxCOMex: COM Express [ http://pixhawk.ethz.ch/electronics/base_large ] (COMExpress
baseboard without CPU, needs a micro COM Express Board on-top, e.g. Intel Core
2 DUO 1.86 GHz from Kontron)
pxFTDIx4 [ http://pixhawk.ethz.ch/electronics/ftdi_x4 ] (4x USB to 3.3V
All you need for a quadrotor are the following parts:
4x BLMC (e.g. Mikrokopter BLMCs)
4x Motor and Propeller
Which makes pxIMU the smallest quadrotor solution currently available (think
of a mini-quadrotor for indoor flight) and, as it combines the functions of multiple
boards in other projects, also relatively cheap.
The image on the right shows the pxIMU Autopilot / Inertial measurement unit
in a typical fixed-wing setup. One of the questions below asks wether you would
prefer to merge these two boards into one. For flying a quadrotor no extra board
would be needed, as the PPM from the remote can be directly fed in and the I2C signal
for the motor controllers is directly sent from the IMU.
pxPower - Power supply and servo output board, 20g
Futaba FASST standard receiver with PPM sum signal mod [ http://pixhawk.ethz.ch/tutorials/receiver_sum_signal
] (other receivers work as well, e.g. ACT DSL, Spektrum Satellites (no main
receiver required), etc.)
GPS Module (not shown on the image)
Differential pressure sensor (not shown on the image)
Please note the USB cable on the pxIMU. It is only for flashing the device
over USB and not used in flight. Flashing over serial is also possible.
Please fill out the poll below, it will significantly help to improve the
module. Please also use the discussion field on the bottom of the page to give additonal
Mailing List and Discussion
We like to get feedback! Please join the PIXHAWK mailing list/Google group and/or
leave a comment on this page. Do you own/work in an electronics company and you
think that you can make a better/cheaper offer for the production? Contact us! We'd
like to offer the community the best price we can.
