I would like to know :1. 5V input : Recommended operation voltage range ? Since I´m coming from APM/PX,which are limited to certain op voltage, and experienced that so called 5V BEC provide voltages…Continue
"Marc, please specify the Board with the u-blox NEO 8 (M8N ?) you are using. Or we will start to call the Brains just just ARM 32 F4, which is only part of the story. I personally own 4 different GPS boards with NEO M8N , one with MAX M8Q,…"
"Looks nice, just one rec. DJI changed @ E300 ESC to two caps in order to achieve a more flat design. Never mind attaching LED, since they do it only @ Phantom ESC. Btw. its BLHeli, probably the best FW out."
"-rc10 now works well as well as the -rc9 did. It wasn´t GPS reception...My MAG calibration has been messed up, and -rc10 requires reboot after flash.. I´m not sure about different EKF behavior. Switching between DCM / EKF still causes…"
"Thx Marc , it worked for me , I already did the upolad to ubrain with MP yesterday night and tried it this morning , which wasn´t too lucky though, probably due to bad GPS reception.
Concerning USB , I´ll have to find someone for…"
3.2 rc10 is online with APM mission planner. I had some success with my Vr Brain 4.5 but no way to do it via APM mission planner with my µBrain. I had to download firmware archive and make a DFU file for dFuse demo to upload…"
"Hi Roberto, EKF was the main reason, I prefer the uBrain over the Mini Versions of the APM. I am pretty sure that this great step ahead will be a standard pretty soon and bury other platforms not being able to handle . SBUS is important as well.Thx."
"Now the upload topic is solved. I was able to take it out of the VRX_binary-master and used the .vrx file.
But its much better now, since emile announced, that the recent sum rx version (-rc9) is hidden behind the 3.15 buttom. Thx."
"Edit: The diagram above is correct. For first trials (@ 3s) just use one 470 Ohm resistor connected to +V Bat commonly leading to + of two cheap LED and a KK Board buzzer. Not really bright, nor loud, but a fast no risk solution for those which are…"
Here is my second support request:Since the uBrain came with AC3.2-rc2, I wanted to update with rc7 .The MP (recent version) shows this :This is probably no problem, since I downloaded the recent (complete) package from VR and I can upload custom FW via MP onto the uBrain.Question is , since the MP takes .hex files and .vrx and both are offered @ by the VR FW package...which one to choose, v51.hex or v51.vrx ?…See More
I would like to know :1. 5V input : Recommended operation voltage range ? Since I´m coming from APM/PX,which are limited to certain op voltage, and experienced that so called 5V BEC provide voltages between 4.8-6V, I would like to know the recommended,safe operation voltage range for the uBrain, e.g. 4.7-5.9V ?2. ULN 2003 : Recommended operation wattage/mA (total) ? E.G. 500mA @ 3s (12,6V)3. LED / Buzzer / V_Batt : Since I did not find a diagram,and did not clearly understand your Wiki picture,…See More
