Re: [Paparazzi-devel] minimal input voltage for the tiny 2.1

[Michel GORRAZ]

Typping error, sorry : read Vin min = 6.1v :

- based on the PTH08080W datasheet (page 3) : if  3.4 V < Vout < 5.5 V, Vin min = Vout + 1.1V
- on tiny v2, Vout = 5V, so Vin min = 5 + 1.1 = 6.1v

...and Vin max = 18V...

I have tested the supply down to 5.5V which I thought was the rated minimum.  Below 5.5V the 5V line goes to Vin - 0.5V and I verified this under load as well, down to 3.5V where the MCU crashes.  I hope you are incorrect Michel, because 6.6V will not work for 2 cell lipo which can easily go below 6V under load when depleted.

Hi,
In order to maintain the 5v power supply for the servos, the minimal input voltage for the Tiny v2 is 6.6v : so you can fly with a 2 cells lipo...

Hi,
what is the minimal input voltage for the tiny 2.1?
Can i fly with two lipo cells?
