Please confirm the date of delivery to Poland, thank you

The date is displayed on the product details page (for reference only), you can also consult Amazon's official customer service. Thank you for your understanding and support.

I'm interested in using this sensor with an Arduino Nano. Are there any arduino libraries or code examples?

Instead of the nano I've used SeedStudio XIAO 52840 Sense (Available from Amazon) The Sense version has integrated accelerometers. , BLE, WIFI, and LiPo battery charger. It can be used with Arduino IDE and has sample programs to capture sensor data.

Can this be used with open source flight controllers such as inav or betaflight?

Thank you for your question. This requires the adaptation of the protocol. The specific use effect is subject to the actual situation.
