Nice work !!
I need one for tracks robot !
You have to try JLCPCB it's really cheap and good quality

As soon as board for backers are sent you will be able to order your board if you want=)

can you add + and - pad for Vbattery when we use 3s lipo ?

[Mike118]

In such a case you can still connect to V+ and V- but do not put jumper to link V1 and V+ nor V2 and V+. You will need to provide your own 5V or othe voltage you want for your servo on V1 and V2.
@James Flosse (Snyp) is this option ok for you?

[Snyp54]

high risk with this option :/
i don't like when high power an low power are so closed

[Mike118]

why do you want to put 3S on this board ? You can just connect your 5V Bec on this board...
@James Flosse (Snyp) other option, if you really need a 12V bus, because we added "the veroboard part " you can solder anything you want there.

[Mike118]

So is that ok for you or you still have a request ?

[Snyp54]

no ^^

[Mike118]

Ok I will take it as " no i don't have more requests "

wow that's a pretty cool board. i can totally see how that can be useful!
the silk screen at the bottom pad is a bit confusing. it took me a while until i figured out why there's a V1 label when the whole line already is V1.
specifically the small rectangle silk at the V1 / V2 pads at the bottom.
it's a cool board

[Mike118]

Two little jumper will be provided with the board
@fire_ned the jumper can be used to connect V1 V+ and V2 V+ with V+ being the battery 1S input.
but you can also choose to connect V1 with 5V instead and V2 with 3V instead but of course if you do so do not connect V+ with V1 or V2 if already connected to another voltage...

[firened]

yes. quite ingenious design

[Mike118]

I don't know if you will find it usefull or not but there is also the 4*12 veroboard space where you can solder any component you need. And around the veroboard space there are the four voltage available V+ GND 5V 3V in order to easily make a strap with a wire.

Good the the I2C fuel gauge for exemple

[Mike118]

yes the I2C fuel gauge of the ups board can be soldered there
add on this hat our custom fuel gauge or the sparkfun one https://www.sparkfun.../products/10617 a 5V step up https://fr.aliexpres...3037394080.html and the charger https://fr.aliexpres...3032500223.html and you will have a ups board hat for maker ^^

Vigibot firmware is able to dectect low battery voltage and turn of the PI ?

[Mike118]

Currently there is no clean raspberry pi "auto shutdown" but it is not very difficult to implement it. Instead off keeping some juice to properly shutdown the robot we prefer keep all the juice to try to save the robot from dying out off battery... This is why ... But we may add an option if there is multiple people asking for this feature...
