I2C bus lines

The KAmodMMA8653FC module is equipped with jumpers allowing to connect pull-up resistors to the positive power pole to the I2C bus line. The jumpers give the possibility of independent enabled of the pull-up for the SDA and SCL lines.

Battery connector

The KAmodM41T82 module has been equipped with a connector enabling the connection of a battery supporting the power supply in the event of a main power failure. Thanks to this, the module will not lose data regarding the time measured and will allow for uninterrupted work. A battery with a voltage between 2-5,5V may be connected to the connector.
