IMU Board (3D Gyroscope & 3D Accelerometer) (Wi-Fi & Bluetooth)

Hardware

The IMU Board is powered by the Espressif ESP32-WROOM-32E module, featuring two 32-bit LX6 Xtensa MCUs. This versatile module supports Wi-Fi (802.11 b/g/n), Bluetooth Classic, and Bluetooth Low Energy (BLE), enabling a wide range of applications, including:

• IoT devices
• AI/ML edge computing
• Low-power sensor networks
• Audio streaming
• General control systems

Key features include:

• Rich peripheral set: SPI, I2C, I2S, ADC, UART
• 4 MB flash memory for program storage
• Integrated 3-axis gyroscope and 3-axis accelerometer with temperature sensing
• Standard 0.1” header spacing for easy bread board prototyping
  

Capabilities

Motion Sensor

The board uses the TDK InvenSense ICM-42688, a high-precision 6-axis MEMS motion tracking device, combining:

• 3D digital accelerometer (±2, ±4, ±8, ±16 g)
• 3D digital gyroscope (±15.6 to ±2000 dps range)
• Digital interface via I2C to the ESP32

This sensor provides reliable motion tracking for robotics, navigation, VR/AR devices, and gesture-based controls.

Wireless Connectivity

• Wi-Fi: 802.11 b/g/n, data rates up to 150 Mbps
• Bluetooth: Classic + BLE for low-energy applications

Software Compatibility

The IMU Board is designed for flexible development, supporting:

• Arduino framework – Arduino Store
• MicroPython (with Thonny IDE) – Thonny.org
• Example code available on GitHub: OBS-DEV-ENG
