Hello,
May I ask what would be the most efficient on-board antenna for ZOE-M8Q in general purpose?
Thank you,
Jun
This one works well https://www.sparkfun.com/products/9145 - though, depending on your use-case/needs, you might want to look into the https://www.sparkfun.com/products/15210 which is very similar but has an on-chip antenna
Hope this helps!
