Introduction

The Makerfabs IMU Module features the 6-axis MPU-6050 MEMS sensor from InvenSense. Each of these 6DoF IMU features an ESP32 with an MPU-6050 which contains a 3-axis gyroscope as well as a 3-axis accelerometer. The MPU-6050 uses 16-bit analog-to-digital converters (ADCs) for digitizing 6 axes. By combining a MEMS 3-axis gyroscope and a 3-axis accelerometer on the same silicon die together with an onboard Digital Motion Processor™ (DMP™). It can be used as a helicopter/quadcopter.

Model: IMU
