Qiotek ASP5033 Digital Air Speed Meter Sensor Kit for Pixhawk APM PIX Flight Controller RC Airplane

The ASP5033 driver has been incorporated into the ardupilot firmware. ASP5033 I2C sensor requires firmware version above arduplane 4.1 and firmware version below arduplane 4.1 or PX4 autopilot firmware, Please purchase ASP5033 CAN interface module.

In view of the fact that the official 4.1 firmware does not have a specific release date, we provide ardupilot 4.0.9 stable firmware driven by asp5033, which can be used through custom firmware flash.

At present, we can provide the following compiled flight control 4.0.9 stable firmware. If you need other flight control firmware, please contact customer service to compile it in advance. After the official version 4.1 firmware is released, we will delete the following firmware. Please use the official firmware directly.

provide for these board firmware:

The differential pressure sensor, digital output using I2C interface, the total error within the compensation range is less than 0.5%.

Automatic matching dynamic pressure & static pressure, Just the dynamic pressure and static pressure connected to the pitot tube are OK

Adopt GH1.25 terminal interface. The distribution terminal cable can be directly linked directly to the flight control I2C expansion board.

Sensor: Automatic matching dynamic pressure & static pressure

Corresponding to the connection of the airspeed tube

The arrow is installed forward of the aircraft. Connect the pitot tube two holes to the sensor holes.
