@jezerca said in 10000 mAh Li-Po battery with TTGO T-Call&PMU SIM800L ?:

Hi all,
Expect the long charging time, would there any problem to use such kind of battery? Does the AXP192 board support it?

Hi. You can use this 3.7V battery, the default charging current is 500ma, you can modify it by programming.

esp32 uses FFAT32, the file system supports up to 32G

@destroyedlolo Great idea, we actually already have a similar product. Such as T-SIM7000 series.

Only the welding port of the BME280 sensor is reserved. The default is without BME280 sensor.

@scheeri about 200ma

@scheeri It can be connected to 5v, but after connecting to 5v, you cannot plug in USB at the same time.

@erongd Cool .👍

@fdaher 👍

D1 and D2 pins are I2C

@caz that's great , if you have any other questions in use, please feel free to contact us.

hi, GPIO35 is usually used as a battery status detection pin. Can you post pictures of your products? We can correspondingly find the schematic diagram to give you accurate answers. thanks.
