About the MotionSense-IMU PCB

MotionSense-IMU is an open source PCB design by igilarranz, published on GitHub. It is a 2-layer board measuring 35.4 × 27.5 mm, with 12 components from 8 distinct parts.

Other key parts include the AP2112K-3.3 and LSM6DSM. By type, the board carries 4 capacitors, 4 resistors, 2 ICs and 2 connectors.

It belongs with the sensors, dev boards & breakouts and test & measurement designs in this gallery.

From the project

2-layer USB-C powered LSM6DSM IMU breakout board designed in KiCad

MotionSense IMU is a custom 2-layer PCB built around the ST LSM6DSM 6-axis accelerometer and gyroscope.

The board takes 5 V from USB-C, regulates it to 3.3 V, and breaks out the IMU's I2C interface and interrupt signal through a 5-pin header.

LSM6DSM 6-axis accelerometer + gyroscope AP2112K-3.3 LDO regulator USB-C 5 V input 4.7 kΩ pull-up resistors on SDA and SCL Decoupling capacitors for the regulator and IMU 5-pin interface header 2-layer PCB Board size: approximately 35 mm × 27 mm
