Hi all MINIM OSD users, I'm investigating about a bug on RSSI screen indication, but I've not the necessary H/W to test it. Will be usefull for me have some help about the signals directed on MINIM in order to simulate it: 1) RSSI signal PWM type : Voltage level (may be max 5V?) and what is the min ...

Hi Kata, My 2nd minim board (rctimer version) worked okay at home, but it's malfunctioning now when I did flight test this morning, still dont know why .

If I can add a suggestion, For the ALT reading, add an option that will allow it to 0 on arm. ie: Sensor shows 539 ft when disarmed, when you arm and take off, your "home" point is 0 ft, instead of 539. Which MWii version are you using? I know that with an old MWii vers. at statup we had ...

Yes, in the middle is RSSI icon and you can disable entering in OSD menu page 4 and set it to OFF.

I forgot to tell that since 150-200 cm/s is quite fast for descending, first of all you should have perfect PIDs on all axes , and perhaps should have some TPA adjustments too.

Hi Kata and other developers,
