"For anyone elses notes, Pins 1 and 5 are 0V for the Radio port and 5V when USB is connected. I confirmed that those levels are correct for my board and yet the data from the radio isn't making it on Radio.
The data still has to go through TS5A23157, and that is where I think my problem is. It isn't switching from the data to travel through the telemetry port while the USB connection works fine. SJ1 and SJ4 are hardwired to…"
"Thanks for all the help. I learned a few things today.
The hardware warranty from 3DR Robotics is only 90 days from date of purchase
That I am 90% sure that the failing part is the TS5A23157, so since they are only $1.10 each from Digikey, I…"
"Here is what I have learned so far, but it seems like the the TS5A23157 could be bad. 2014-07-16 09_28_38-1 Schematic - C__Users_Mike_Documents_APM_APM_v..."
My problem is that I am trying to figure out why I don't have Telemetry on the 3DR port when powered by the power module. It isn't a radio configuration issue as I have actually had them…"
Would anyone know if there are Eagle files for the 2.6 board?I have an intermittent connection on the 3DR connector for some reason and I want to know if I can jumper over to the pads labeled UART2.Mike
I ordered 5 of them. If you want to send me your board, I can fix it if you are not comfortable doing it. Zoltan at NGHobbies in Woodbridge (Toronto) can do it also.
From what I read, adding the cap on the +5v rail really helps too.…"
I've jut built up an EasyStar II and did the first test flights tonight.I did some testing with Loiter which for the most part worked fine. I did a have a funny glitch in the path of the plane while it setup for Loiter. I almost reached for the…
