CUAV Core X7 and NORA experience

@maciek252

Many thanks for your answers, but I haven’t been able to identify an exact plug type. Is this something of that kind?

(of course here is 10pos and discontinued, but I could even cut it to fix)

It is the good one. You can have it with 6 connectors.

Hi! I’m working with X7 pro but I’m not able to monitor the battery.
Do you know if I can adapt some of these values to my set up ? (10000mAh 12S battery and X7 pro, in addition Im using the PMU SE of CUAV connected to Power C port) .
I cannot find proper documentation about how to parametrize those values. Thanks

Hi @mlebret , @xfacta ,
I have problem about the Battery remaining Indicator (In percent) that shows very fast current consumption which is NOT consistent with “battery consumed” indicator on the same display. Any idea how to solve this problem? I have tried to increase the total battery capacity parameter, but problem still exist. Anybody could help how to solve this problem? Thank you.

I have created new thread about this Battery Indicator Problem here:

Cuav nora battery remaining indicator (using can pm) is wrong, but current is correct, how to solve?

I have built two same quad copters with same configuration using CUAV NORA, and 6S battery. Both have same problem: Wrong battery remaining indicator. Nora supplied CAN Power module in the package (lite version), so I followed all the instruction, that this CAN PM should be installed on the C power port of NORA. Battery monitoring parameter is set to 8 , so Battery Voltage and Current are correctly displayed as expected without any adjustment/calibration. Both Quad copters fly well, however so…

Use the initial parameters calculator to set the correct battery voltage-related parameters for a start.

Hello,

two questions about the CUAV Nora:

• what are the pins for BATT2? Is BATT2_VOLT_PIN=4 correct? What is the setting for the current?

• it has been announced in one of the threads that Nora will finally get the UART3 (the one on the side) enabled. I’m looking at the release notes and can’t see that this has happened. Any news?

[cuav_le]

• BATT_V0LT_PIN=16
• BATT_CURR_PIN=17
  nora supports only one analog power supply. UART3(Serial7) is already supported, please enable it in all parameters.

Thanks for your answer. I can confirm that the battery2 pins are working fine. Will check the UART3. Please update the docs:

including adding the detailed description of differences between Nora and Nora+, in particular if DSHOT telemetry is expected to work for the former one and for which outputs.
