SDA?

[Saikho-Labs]

Hey all,

So recently I soldered together a mintypi v3 but my SDA pin never had continuity to the test pad. I connected a wire to the test pad directly however the pad came off. I am unsure if there is a connection but wanted to know if it is a necessary pin for basic functions. I read it's for BT or WiFi but I dont plan to use either if that helps the situation.

Thanks!

I believe that is for audio, so you should connect it. Send a picture and we can help
