This is a list of tested hardware for the BBBMINI. If you have other hardware in use, please let me know, so I can update the list.
OrangeRX R615X and R815, via S.BUS, 3.3V VCC, R4 = 0 Ohm, R5 = not used (open)
When I get some spare time I'll also test out my RFD900 radios..... May take me a week or two to get to it.
does the R825 is working reliable with only 3.3V. The input voltage should be 3.7V and 9.6V ?
Just checked that with my R615X if you are using 5V VCC, the CPPM signal is still 3V.
My hardware tested
Hi Mirko, Seems I was confused the other day (can you edit a previous post older than 15 mins?).... Yes signal is 3.3 regardless of input voltage it seems.
It should be:
I was about to test my R815 again when I accidently put it through reverse polarity, lets just say it didnt like it. I think I've blown the voltage regulator, I think it's a 7333A in a SOT89 package, can anyone confirm if that right? My other R815 went on a one way flight a month ago, so I cant compare it unfortunately..... I cant read the figures off my R615X, it's too small even with a magnifying glass, thinking of pulling out the DSLR with good zoom to see the writing....
I have a RCIN 5V board with just a bridge on R4, once I fix up my voltage reg I'll see if it works on that one.
Once I fix the R815X I'll put it up too.
I think that it puts the 5V input rail through the regulator for all the electronics on board so I reckon that is why the signal is only 3.3V.
Once I do up a couple of plugs to prevent me from putting reverse polarity, I'll try my OpenLRS RX's on it.
I can add three GPS's to the list.
I have few other stuffs but I will test this setup first to do more tests and update this post.
Thanks, Vinicius, could you tell me the value of R4 and R5 please.
Hi Mirko, I'm using 2k2 and
I was flying yesterday for first time and I was with an issue. Sometimes the controls are not been working, for instance, I try a yaw for some degrees and the command was ignored. In first impression was just a Yaw problem, but testing - my total time was around 15 minutes, I see this happens for all commands.
I was looking logs and I didn't see anything wrong, so my next step is first, change the PPM Encoder for a second model, and then use a DR8-II receiver - I ordered some cables to update firmware and can use ppm encoding directly from the receiver.
BTW, this frame is my test frame, so with same setup I tried Crius 1.1, Crius 2.0, Apm 2.6, Naze 32 and the bests results was with BBB Mini - extremely stable and precise - even with this minor issue of control.
