Hello.

I’m looking for an antenna andcable that can be connected to the Xiao nRF54L15’s ECT818000500.
Can you tell me where I can purchase one?

Indeed, I got my hands on an engineering sample of one, and it literally took me 5 minutes to get the connector latched on.

According to a statements on the seed discord,

“The accompanying external FPC antenna for the XIAO nRF54L15 is expected to be available by the end of October.”

And it will be listed in the normal SEEED web store for purchases.
