I am a sensor expansion board specially designed for Raspberry Pi. It has a gyroscope, accelerometer, magnetometer, barometer, temperature and humidity sensor, etc. onboard. I2C interface communication supports more external sensors.

If you want to DIY the Raspberry Pi into a robot that can detect movement posture and orientation, or want the Raspberry Pi to collect sensor data such as temperature, humidity, and atmospheric pressure in the surrounding environment, then take me.

Features:

Onboard Raspberry Pi 40pin GPIO interface, suitable for Raspberry Pi series motherboards

Onboard ICM20948 (3-axis acceleration, 3-axis gyroscope and 3-axis magnetometer), which can detect movement posture, azimuth and magnetic field

The onboard SHTC3 digital temperature and humidity sensor can sense the temperature and humidity of the environment

The onboard LPS22HB atmospheric pressure sensor can sense the atmospheric pressure of the environment

Onboard TCS34725 color recognition sensor, which can recognize the color of surrounding objects

Onboard ADS1015 chip, 4-channel 12-bit precision ADC, expandable AD function to connect more sensors

Leads out the I2C control interface for easy access to the main control board such as STM32

Parameters:

Working voltage: 3.3V

Communication interface: I2C

Logic voltage: 3.3V
