CAUTION:
DO NOT put any non-rechargeable battery, like dry cell, into the battery holder. Serious consequences including explosion may occur if you try to charge a non-rechargeable battery.
DO NOT put any non-rechargeable battery, like dry cell, into the battery holder. Serious consequences including explosion may occur if you try to charge a non-rechargeable battery.
SAFETY MEASUREMENTS:
- Li-ion and Li-po batteries are quite unstable. They may cause fire, personal injury, or property damage, if they're not properly recharged or used.
- Do not reversely connect the polarities when recharging or discharging the battery. Do not use inferior charger/charging panel to recharge the battery.
- Do not mix use old batteries with new ones, avoid using batteries of different brands.
- When buying Lithium battery, should always make sure the battery specification is compatible with the expansion board. Choose batteries from formal manufacturer, and ensure the batteries will work stably and safely by aging test.
- Lithium batteries have limited cycle life, they will also deteriorate as time goes by. Should be replaced with new ones when the batteries reaching their max cycle life, or working over two years, whichever comes first.
- Should be placed carefully and properly, keep it away from inflammables and explosives articles, away from children, avoid any safety accident caused by careless storage.

10-DOF IMU Sensor Module for Raspberry Pi Pico Onboard MPU9250 and LPS22HB Chip (ws pico 10dof)
Incorporates 9-axis motion sensor MPU9250 and baroceptor LPS22HB
Raspberry Pi Pico header compatibility
Features at a glance
The Pico-10DOF-IMU is an IMU sensor expansion module specialized for Raspberry Pi Pico. It incorporates sensors including gyroscope, accelerometer, magnetometer, baroceptor, and uses I2C bus for communication.
Combined with the Raspberry Pi Pico, it can be used to collect environment sensing data like temperature and barometric pressure, or to easily DIY a robot that detects motion gesture and orientation.
- Standard Raspberry Pi Pico header, supports Raspberry Pi Pico series
- Onboard MPU9250 (3-axis gyroscope, 3-axis accelerometer, and 3-axis magnetometer) for detecting motion gesture, orientation, and magnetic field
- Onboard LPS22HB barometric pressure sensor, for sensing the atmospheric pressure of the environment
- Comes with development resources and manual (Raspberry Pi Pico C/C and MicroPython examples)
