KX134-1211-EVK-001 Manual
KX134-1211-EVK-001 is an evaluation board for KX134-1211 accelerometer. This User’s Guide will show how to use KX134-1211-EVK-001 together
with Accelerometer Evaluation Kit that is sold as RKX-EVK-001.
Preparation
⚫KX134-1211-EVK-001 1pc
⚫RKX-EVK-001 1pc
Setting
1. Download and Install the latest release of the RoKiX
Windows GUI following this link:
https://www.rohm.com/support/accelerometer-evk-support
Note: After installation, the shortcuts to the RoKiX Windows
GUI and to the RoKiX Development Kit User’s Guide can
be found on the desktop, in the Windows Start menu under
RoKiX folder, and in the installation directory:
\Documents\RoKiX\
2. Start RoKiX Windows GUI. If Configuration update pop-up
window is shown, click Yes to download the latest
configurations from the server.

3. (Optional) The CY8CKIT-059 PSoC® 5LP Prototyping Kit
comes preloaded with the custom firmware when
purchased as part of RKX-EVK-001. The latest version of
the firmware can be found in the installation directory:
\Documents\RoKiX\RoKiX-Firmware\Cypress-PSoC
Note: The guide for programming the custom firmware to
the Cypress CY8CKIT-059 PSoC® 5LP Prototyping Kit can
be found in the RoKiX Development Kit User’s Guide.
4. Connect KX134-1211-EVK-001 to RKX-EVK-001 directly
to the 18-pin header J6 or using the provided ribbon cable.

Measurement
Start the RoKiX Windows GUI software and adjust your settings
as follows to get the device connected:
1. Select the board configuration from the Board menu:
CY8CKIT-059 / RoKiX adapter A3 / I2C
2. Select the desired configuration stream for the
corresponding accelerometer sensor from the Stream
menu: e.g.:
KX134-1211 / Accel data 50Hz ±8g high performance
3. If the settings are adjusted properly, data streaming should
start automatically, and the on-screen output should
display real time output for X, Y, and Z axes of KX134-1211
sensor.
