KAmodMPL3115A2

Description

KAmodMPL3115A2 is a module with an atmospheric pressure sensor MPL3115A2 from NXP. The board is equipped with a Pmod I2C standard connector and a KAMAMI connector, that allow to easy connection of the module to the evaluation kits. Due to its small dimensions, the product can be used in many development projects, while the Pmod connector allows to connect the boards in the series.

Basic features and parameters

• MPL3115A2 chip from NXP

I2C bus lines

The KAmodMPL3115A2 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.

Interrupt line INT2

The KAmodMPL3115A2 module has been equipped with a jumper enabling connection of the INT2 interrupt output line to the Pmod compatible connector. Thanks to the possibility of disconnecting the MPL3115A2 interrupt line from Pmod connectors, the user does not have to worry about the consequences of possible conflicts resulting from the connection of Pmod-compatible module modules with different logic states.
