Description

The Pololu MinIMU-9 v5 is an inertial measurement unit (IMU) that packs an LSM6DS33 3-axis gyro and 3-axis accelerometer and an LIS3MDL 3-axis magnetometer onto a tiny 0.8″ × 0.5″ board. An I²C interface accesses nine independent rotation, acceleration, and magnetic measurements that can be used to calculate the sensor’s absolute orientation. The MinIMU-9 v5 board includes a voltage regulator and a level-shifting circuit that allow operation from 2.5 to 5.5 V, and the 0.1″ pin spacing makes it easy to use with standard solderless breadboards and 0.1″ perfboards.

Pinout

PINDescription
SCL Level-shifted I²C clock line: HIGH is VIN, LOW is 0 V
SDA Level-shifted I²C data line: HIGH is VIN, LOW is 0 V
GND The ground (0 V) connection for your power supply. Your I²C control source must also share a common ground with this board.
VIN This is the main 2.5 V to 5.5 V power supply connection. The SCL and SDA level shifters pull the I²C bus high bits up to this level.
VDD 3.3 V regulator output or low-voltage logic power supply, depending on VIN. When VIN is supplied and greater than 3.3 V, VDD is a regulated 3.3 V output that can supply up to approximately 150 mA to external components. Alternatively, when interfacing with a 2.5 V to 3.3 V system, VIN can be left disconnected and power can be supplied directly to VDD. Never supply voltage to VDD when VIN is connected, and never supply more than 3.6 V to VDD.
SA0 3.3V-logic-level input to determine I²C slave addresses of the two ICs (see below). It is pulled high by default through 10 kΩ resistor. This pin is not level-shifted and is not 5V-tolerant.
