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.

Not for the faint of heart

Incomprehensible manual, never achieved connection with an Arduino

Horrible Quality Control, ordered two, one failed during testing. This is what I found!

I opened the case and removed the failed part, I don't know why it failed, but there was a little chunk of solder floating around in the case. It also became clear for reasons unknow the manufacture had "tried" to lift off, or scrape off different sections of the copper land. But they left part of it sticking up, soldering very rough on several areas. I don't know why it failed, but very likely the solder chunk shorted out something.

No computer connection.

Not wireless. Wires dangling out that you have to figure out what to do with them. Useless for me. Just use free cell phone app. I think it can do everything this device might be able to do. Save your money.

Unable to use with Arduino

Unable to use with Arduino. Severe lack of information. Returned for refund. Purchased WT901C-TTL. It works with Arduino.

Disappointed .....

Much to difficult to set up with the instructions provided. Is this sensor for Android or IPhone or PC?
