Hey Fergus,

Welcome back to the forum.

I have just updated the product page with a translated datasheet, our attachments can take a quick sec to upload, but you should have access to it soon!

Could you elaborate on what you meant by the above? I’m not super familiar with this board myself but I may be able to help with a bit more info.

Hi Peter,

Was the issue that it is poorly translated or does the link not open a .pdf at all?
The link is working for me though I’ll admit the auto-translation still needs some improvement.

Thanks Peter, the datasheet is good. There are some videos it links to which are all in Chinese.

We would like to be able to connect remotely to the Bluetooth module and be able to read and write some GPIO pins. Thanks
