6DOF IMU click
Product Information
The 6DOF IMU click is a click board that carries Maxim’s
MAX21105 6-axis inertial measurement unit. It consists of a 3-axis
gyroscope and a 3-axis accelerometer. The chip provides highly
accurate measurements and operates stably over a wide temperature
range. The board can communicate with the target MCU through
mikroBUSTM SPI or I2C interfaces. It requires a 3.3V power
supply.
Product Usage Instructions
- Soldering the headers:
- Before using the click board, solder 1×8 male headers to both
the left and right sides of the board. - Turn the board upside down and place the shorter pins of the
header into the appropriate soldering pads. - Turn the board upward and align the headers perpendicular to
the board. Carefully solder the pins.
- Once you have soldered the headers, your board is ready to be
placed into the desired mikroBUSTM socket. - Align the cut in the lower-right part of the board with the
markings on the silkscreen at the mikroBUSTM socket. - If all the pins are aligned correctly, push the board all the
way into the socket.
Once you have done all the necessary preparations, you can start
using your click board. Examples for mikroCTM, mikroBasicTM, and
mikroPascalTM compilers can be downloaded from the Libstock
website.
The board has three sets of jumpers:
- INT SEL: Used to specify which interrupt line will be
used. - COMM SEL: Used to switch from I2C to SPI.
- ADDR SEL: Used to select the I2C address.

6DOF IMU click
1. Introduction
6DOF IMU click carries Maxim’s MAX21105 6-axis inertial measurement unit comprising a 3-axis gyroscope and a 3-axis accelerometer. The chip is a highly accurate inertial measurement unit with long-term stable operation over a wide temperature range. The board communicates with the target MCU either through mikroBUSTM SPI (CS, SCK, MISO, MOSI pins) or I2C interfaces (SCL, SDA). Additional INT pin also available. Uses 3.3V power supply only. Downloaded from Arrow.com.
2. Soldering the headers
Before using your click boardTM, make sure
to solder 1×8 male headers to both left and
right side of the board. Two 1×8 male headers
are included with the board in the package.

Turn the board upside down so that the bottom side is facing you upwards. Place shorter pins of the header into the appropriate soldering pads.
Turn the board upward again. Make sure to align the headers so that they are perpendicular to the board, then solder the pins carefully.
4. Essential features
6DOF IMU click is suitable for designing platform stabilization systems, for example in cameras and drones The MAX21105 IC has a low and linear gyroscope zero-rate level drift over temperature, and low gyroscope phase delay. 512-byte FIFO buffer saves resources of the target MCU. The gyroscope has a fullscale range of ±250, ±500, ±1000, ±2000 dps. The accelerometer has a full-scale range of ±2, ±4, ±8, ±16g.
3. Plugging the board in
Once you have soldered the headers your board is ready to be placed into the desired mikroBUSTM socket. Make sure to align the cut in the lower-right part of the board with the markings on the silkscreen at the mikroBUSTM
socket. If all the pins are aligned correctly, push the board all the way into the socket.
