Removing apm 2.0 shield

Started this discussion. Last reply by Greg Owen Jul 24, 2012. 11 Replies

Has anyone removed the shield to allow remote location (for traditional heli)?Looks like it's possible to desolder the 6 pins (actually only 4 are soldered), and make an extension harness.Continue

MediaTek GPS and APM supply voltage, level shifter?

Started Oct 23, 2011 0 Replies

     I'm wondering if a 3.3 to 5 volt level shifter would provide more robust serial communication between the GPS and APM.   I don't see one, looks like the tx/rx lines just go straight between the…Continue

"How do the motors sound so cool and quiet?  Is it the isolation from the arm mounts?  Or are they big heavy motors and they look like pretty low kv?"

"Touched up the solder on the x y and neighboring pins.  now the y axis works normal again.   But the x axis output seems shorted to ground.  At the pins on the ADC, the y and z are 1.6 +- now, but the x is 0. "

SPI between ArduPilot, ArduIMU, SCP1000

Posted on January 4, 2010 at 10:30pm 15 Comments

Finaallly tonight got this to work more completely. SCP baro sensor to IMU was not so hard. Getting IMU and Pilot to work was more trouble for me.



The layout I chose is: ArduIMU is spi master, SCP1000 and ArduPilot are slaves.



ArduIMU requests airspeed from the ArduPilot, it will be used in combination with the gps based speed in the IMU. It will send the resulting AHRS data to the ArduPilot, as a predefined message, with variables in a certain order. The IMU requests baro… Continue
