Hello All.I am building a project which requires two servos and two escs attached to by ArduPilot at once. Is it safe to plug both ESCs into Ardupilot at the same time, or will this give it too much…Continue

I am on the process of testing all electronics , before running the motors.
I would like to power transmitters and video TX, from an external power source ( I have not received my lipo battery yet),
So how could i power , the TX…"
Charles Winter replied to Shyam Balasubramanian's discussion IMU: Runs Infinitely!! Help Required..."This value is multiplied by the output of the sensors. I'm not brilliant at programming so couldn't figure out why it kept returning 0 for me, guess its something to do with floating points. You could just calculate the value by hand and…"
Luke Olson replied to Charles Winter's discussion Multiple ESCs and Servos attatched at once."Using more than one BEC (or ESC with a BEC) works fine in parallel *** only if the BEC is linear ***. If the BEC is switching this won't work and might cause damage. Most smaller ESC have a linear BEC but check the specifications for the…"
Søren Kuula replied to Charles Winter's discussion Multiple ESCs and Servos attatched at once."Hi,
That is topic often raising discussions. Principally, one should not connect voltage sources in parallel. In reality, there are rarely or never any problems with doing that with ESCs/BECs. They just have to have the same 5V rated output voltage.…"

"There is a blocking diode between the USB connection and the output rail so you cannot power the servos from the USB power."

Hello All.I am building a project which requires two servos and two escs attached to by ArduPilot at once. Is it safe to plug both ESCs into Ardupilot at the same time, or will this give it too much juice? I am using the 2560 board.Thanks in advance,Charles.See More
Charles Winter replied to Shyam Balasubramanian's discussion IMU: Runs Infinitely!! Help Required..."Hi Shyam.
I have just spent about half an hour trawling through the header files and have finally solved it. The problem lies in the file AP_InertialSensor_Oilpan.c
The values for _accel_scale.x, y and z are declared so as to always return 0. fix…"
Zoltan Horvath replied to Charles Winter's discussion Powering the Ardupilot Board"Thanks Chris for your quick reply! I have already powered my APM 2.5 on the output rail and the USB port at the same time, no issues. The alarm level for the RX supply is set to 4.6V as default and with my quick test gear (awaiting the frame and…"

"Zolton: I'm not quite sure why people thought you couldn't power the original APM 2.0 with both USB and the output rail at the same time (you could), but at any rate APM 2.5 is the same. You can power it from USB and ESC at the same…"
Zoltan Horvath replied to Charles Winter's discussion Powering the Ardupilot Board"Hello everybody,
While the APM2.5 is already available, would be great if somebody could refresh this topic. What are the major changes regarding the powering this board? Everything which was described here guilt for the new board too or we have now…"
DahaS replied to Charles Winter's discussion Powering the Ardupilot Board"A10 and A11 is from Amtel2560 so will be powered from wher you let your board to get power and is the same as A0 - A9. Sorry im not home and i dont have board with me but im 90% positive about this.
Think about why was this board made to be you guid…"
Josh Potter replied to Charles Winter's discussion Powering the Ardupilot Board"I've yet to fry anything with dual power and a USB, has something changed?"
John Grouse replied to Charles Winter's discussion Powering the Ardupilot Board"Hang on, the Vin on the base of the APM1 board says 6V-12V. If I de-solder the pad and put a jumper across from the 6V common rail to that Vin it should work. The APM's own voltage reg will drop it to 5V. Not sure how that…"
John Grouse replied to Charles Winter's discussion Powering the Ardupilot Board"I've got the APM1 board and IMU (oilpan). I can see the solder pad which can be de-soldered to separate the ESC/servo common +V rail from the +5V supplied to the APM board. The separate connector to power the the APM is near that…"

"DahaS: #1 is incorrect. You can power from ESC and USB at the same time with no problem. "
