KAmodLIS35DE is a module with the MEMS LIS35DE chip from STMicroelectronics. The chip has a digital signal output (I2C or SPI bus) and allows acceleration measurement in three axes. Thanks to the programmable interrupt generator outputs, it is possible to wake up the microcontroller after detecting free fall or object movement. The board is equipped with a Pmod standard connector and a KAMAMI connector, allowing easy attachment of the module to development kits. Due to its small dimensions, the product can be used in many development projects and the Pmod through connector allows the boards to be connected in series.

I2C interface line

The KAmodLIS35DE module is equipped with jumpers enabling the connection of pull-up resistors to the power supply to the I2C bus line. Jumpers allow the independent activation for SDA and SCL lines.

I2C interface address

The KAmodLIS35DE module is equipped with a jumper that allows you to change the I2C bus address. The jumper allows you to switch the address between the value 0x1C and 0x1D.

INT interrupt line

The KAmodLIS35DE module has a jumper to connect the INT2 interrupt output line to the connector compatible with the Pmod standard. Thanks to the ability to disconnect the KAmodLIS35DE interrupt line from the Pmod connectors, the user does not have to worry about the consequences of any conflicts arising from connecting modules compatible with Pmod with different logic states.

Communication bus

The KAmodLSM303C module has the option of choosing a communication bus between I2C and SPI. The active bus is selected by soldering the jumper in the right place in the form of a 0R resistor on the board. By default, the module is configured for communication via the I2C bus.

Power supply voltage jumper

The KAmodLIS35DE module has a jumper that allows the module to be supplied with voltage supplied to the KAMAMI connector without the 3.3 V regulator. To configure the module in this way, solder the ZW1 jumper located next to the regulator.
