Regulated voltage level? #3
Comments
V1.0 has a 3.3V regulator. V1.2 and V1.3 used a 3V regulator. In theory, you get better battery life with a 3V regulator, since you can use the 4.2V to 3.0V range of the battery. I don't know if it actually makes a significant difference in practice, since the Li-po's voltage is not linear with the state of charge. So if you worry about low voltage, using the 3.3V should be fine (this is the one I use). The microcontroler (nRF51822) used by the Redox support an input voltage between 1.8V and 3.6V. |
I come here from this issue and am interested in integrating this into my Redox. While looking through the repo I got confused about the regulated voltage of the most recent design.
At the bottom of the README it says "Change regulated voltage from 3.3V to 3V", but the schematic mentions a "3.3V regulator" with no further specification of
VREG
. So – which is it?I'm asking because my current hypothesis to mitigate connectivity issues I'm facing is running the Redox at a slightly elevated voltage.
