Technical overview

Connects via the standard 40-pin GPIO header of Raspberry Pi boards; no pin header needed on Raspberry Pi Zero, but one is required for Raspberry Pi 4.
Onboard 9-axis sensor ICM20948: 3-axis accelerometer, 3-axis gyroscope and 3-axis magnetometer with 16-bit resolution.
Onboard barometer LPS22HB for air-pressure measurement; 24-bit pressure resolution, 16-bit temperature resolution.
Onboard temperature/humidity sensor SHTC3: temperature range -30 to 100 °C, humidity range 0–100 % rH.
Onboard color sensor TCS34725: 4 channels RGBC, 16 bits per channel.
Onboard ADC SGM58031: 4 channels, 16-bit resolution, expands the system with external sensors over I2C.
All onboard sensors have distinct I2C addresses and can be used simultaneously: ADS1015 0x48, ICM20948 0x68, LPS22HB 0x5C, SHTC3 0x70, TCS34725 0x29.
Operating voltage 3.3 V; dimensions 65 mm x 30.5 mm.

Commands and examples – verify before use:

sudo raspi-config
sudo reboot
sudo wget http://www.airspayce.com/mikem/bcm2835/bcm2835-1.71.tar.gz
sudo tar zxvf bcm2835-1.71.tar.gz
cd bcm2835-1.71/
sudo ./configure && sudo make && sudo make check && sudo make install
sudo apt-get install wiringpi
wget https://files.waveshare.com/wiki/common/wiringpi-latest.deb
sudo dpkg -i wiringpi-latest.deb
gpio -v
sudo git clone https://github.com/WiringPi/WiringPi
cd WiringPi
sudo ./build
sudo su
wget https://github.com/joan2937/lg/archive/master.zip
unzip master.zip
cd lg-master
sudo make install
sudo apt update
sudo apt install python3-pip

Notes and version constraints

The demo package includes examples for several host platforms (Raspberry Pi, VisionFive2, STM32); not all examples are available for every platform.
On Bookworm systems only the lgpio library is available; bcm2835 and wiringPi cannot be installed or used there.
Mixing different libraries can cause abnormal behavior; restarting the Raspberry Pi resolves such issues.
For serial output problems in the STM32 demo, confirm the baud rate is set to 115200 and the correct connection type (USART2, PA2 TXD / PA3 RXD) is selected.
Before using external sensors over the I2C bus, check for address conflicts.
