T18_3.0 Schematic

[lacrimal]

Hi,
Can you publish schematic for T10_3.0 20190410 ?
Thanks

Yeah that would be really nice. It would be also good if you could add some description.
I like to know if one pin is connected internally to measure the battery voltage a.s.o.
Thx

I'm also interested :)

Please publish schematics for T18_3.0 20190410 !
I'm wondering if there is any connections for measuring battery voltage.

Me too, if you can publish schematics and if it's have the same measuring battery voltage like the T8 2.2 Lion Oled

Best,

[GearWalker]

Please, release it!

I take it this isn't the schematic? (Genuine question, I am just starting out and also looking for it)

from the schematic, battery voltage is on a voltage divider (100k/100k) on pin 35.

LED is at pin 5.

The BME280 isn't populated, but it would be at pins 20/21 for i2c.
