Fuel gauge BQ27441 breakout

Fuel gauge is a special type of accessory for lithium batteries that very precisely measures the state of the battery. This includes current voltage [mV], state of charge [%] and probably most interestingly: remaining capacity in the battery [mAh]. It is used with 1S batteries, and provides all this information via the I2C interface.

On our board you can find easyC connectors which allow I2C communication with microcontroller. Also, there is a JST input for any pouch battery you can find in our offer, as well as quick connect terminal connector for input if your source doesn’t have JST connector.

* For 1S batteries (4.2V)

* Communication: I2C

* Measures: voltage, state of charge, capacity

* Dimensions: 38 x 22 mm / 1.5 x 0.9 inch
