Hi,
I assume that the z-uno can be supplied from a charging LiPo battery (can vary from 3,5-4 V) via the 3,3 V in port, that is regulated by a MCP1700, is that correct?

Input from LiPo
Re: Input from LiPo
It isn't. Z-Uno tolerated up to 3.6. even 3.7 is too big
Re: Input from LiPo
So the only way to connect power via the onboard MCP1700 regulator is to the USB port? If that is the case, can I use lower voltage then 5 V to the USB? I cant go via the NCP1117, it has to high dropout.
Or maybe would my best option be to put a TO-92 LDO in the 3.3 VIN holes, like a LE33CZ for example?

Re: Input from LiPo
Lipo has a really high amount of current flow characteristics.So be careful while you are using it. A small size lipo can make a large amount of explosion.
Re: Input from LiPo
You can use the 5V input for it - but do not use USB AND LiPo parallel.
Use the Lipo for powering the Z-Uno and a serial connection without USB poer for programming, if you need parallel work.
Or use while programming via USB a diode in serial to the LiPo cell - but not for production (because of drop voltage at diode)
I using it since a long time together with solar charging module.
Good idea is to control the voltage via Z-Uno.
