They came with this huge power management board, which I do not need and do not want to build in for space and weight reason. </p><p>I found that there are sets including the connectors from the attached photos. Sadly I cannot send the 3 PX4s back and order such sets but I also do not find any source where I can buy them. I contacted Holybro but didn´t get a feedback so far. Does anyone of you has an idea where I can purchase those connectors?? </p><p> </p><p>I hope I can find help here.</p><p> </p><p>Kind regards</p><p>Andreas<a href="{{#staticFileLink}}9673547065,original{{/staticFileLink}}"><img class="align-full" src="{{#staticFileLink}}9673547065,RESIZE_710x{{/staticFileLink}}" alt="9673547065?profile=RESIZE_710x" width="710" /></a></p></div>TAKEOFF WITHOUT GPShttps://diydrones.com/forum/topics/takeoff-without-gps2021-09-22T06:07:18.000Z2021-09-22T06:07:18.000ZBhaskarhttps://diydrones.com/members/Bhaskar682<div><p>Hi,<br />Im working on a autonomous drones and im using JETSON NANO and flight controller PIXHAWK .Im able to control my drone by giving rc commands on the MAVLINK terminal itself by connecting it with PIXHAWK but now i want a python code from which i can do some operations like:<br />takeoff,left ,right,forward,backward…and i am not using GPS…<br />Can anyone please help me…</p></div>Pixhawk 4 with high voltage digital servoshttps://diydrones.com/forum/topics/pixhawk-4-with-high-voltage-digital-servos2021-06-28T13:04:00.000Z2021-06-28T13:04:00.000ZJohanhttps://diydrones.com/members/Johan246<div><p>Hi everyone!

They are for a thrust vectoring mechanism of an electric ducted fan rocket. From what I've read, a 5V BEC can be connected to the pixhawk servo rails to power them, then the servos can be connected. However, that is for servos operating at 5v. For servos operating >5v, I've heard that one needs to run a 7.4v BEC from a battery, directly to the servos first. The servo + and ground wires connect to the BEC wires somehow. Then, connect the signal wires of each servo to the rails of the pixhawk. I had been searching for a wiring diagram/schematics of this setup as I have never used a digital servo, BEC or flight controller before as I am new to the RC world. In short, a complete novice. So far, I have come across only these few images attached. I would like to know if someone can please provide a schematic or guide as to where I can find this setup implemented. I have checked on google scholar and other youtube videos.<a href="{{#staticFileLink}}9153649068,original{{/staticFileLink}}"><img class="align-full" src="{{#staticFileLink}}9153649068,RESIZE_710x{{/staticFileLink}}" width="710" alt="9153649068?profile=RESIZE_710x" /></a></p></div>Flysky fs i6 not working on pixhawk 2.4.8https://diydrones.com/forum/topics/flysky-fs-i6-not-working-on-pixhawk-2-4-82020-12-26T02:45:45.000Z2020-12-26T02:45:45.000ZNurjana Ariffilah Idrishttps://diydrones.com/members/NurjanaAriffilahIdris<div><h4>Issue details</h4><p>Servos not working on Pixhawk 2.4.8, Im using Flysky Transmitter and IA6B receiver, when I tried to calibrate I found none of the servos were working even after using the arming switch.

The whole weight is 4kgs, and the quad flew for continuous 35 minutes. I was very happy about the long flight time and its good stability. Until last week, and just the second flight when I was trying video recording above a lake, and after 5 minutes flight, the quad began to wobble crazily, and I couldn't control it before it was falling into the lake and sunk. After five hours, I was able to extract it from 3 meters under water ,using a water bike and following last GPS position in QgroundControl.</span><br /><span style="font-size:12pt;">After reviewing the log, and connections, I concluded that the cause might be a disconnected wire from the power board which touched the board and caused it to burn, although the ESCs were directly connected to the battery and the pixhawk directly to the power module.</span><br /><span style="font-size:12pt;">I disassembled all the parts,clean, brush,dry.. and I was happy I could recover all of them except for the pixhawk.</span><br /><span style="font-size:12pt;">After first connect to Pc via usb port, it was powered normally, all leds and main light were functionning OK. But I couldn't power it from battery. Another thing was that I could install the px4 firmware on it but not the arducopter and the main led light never lit. And after a stupid try of installing px4io bootloader from sd card, the pixhawk was no longer seen from MP or Qgroundcontrol, I tried the python loader , it gave a message "waiting for the bootloader" although I tried to hold switch while powering the pixhawk.</span><br /></p><p><span><span style="font-size:12pt;"><strong>Note:</strong> the leds status when connected to pc in normal mode</span>:</span></p><p><strong>IO POWER AND FMU POWER:ON</strong><br /><strong>IO B/E: ON</strong><br /><strong>IO Act: blinking</strong><br /><br /><span>When in boot mode</span><br /><strong>IO POWER AND FMU POWER:ON</strong><br /><strong>IO B/E:blinking</strong><br /><strong>IO Act: OFF</strong></p><p><strong>Images before a<a href="{{#staticFileLink}}5334413883,original{{/staticFileLink}}" target="_blank">20200212_215731.jpg</a>nd after crash and log file are attached</strong><br /><span>Any help to recover my pixhawk back and also resolving powering problem from battery will be really appreciated.</span><br /><span>Thx in advance</span></p><p class="attachment"><a href="{{#staticFileLink}}5334414098,original{{/staticFileLink}}" target="_blank">20200317_154851.jpg</a></p><p class="attachment"><a href="{{#staticFileLink}}5334414853,original{{/staticFileLink}}" target="_blank">20200317_175513.jpg</a></p><p class="attachment"><a href="{{#staticFileLink}}5334415055,original{{/staticFileLink}}" target="_blank">CrashLog.rar</a></p></div>+5v output on a Holybro Pixhawk Minihttps://diydrones.com/forum/topics/5v-output-on-a-holybro-pixhawk-mini2020-02-22T11:05:41.000Z2020-02-22T11:05:41.000ZJames Broughamhttps://diydrones.com/members/JamesBrougham<div><p>I’m trying to get a +5v output on my Pixhawk mini, simple I thought, nope.
