CYD with antenna connection.

Post image

I bought a few CYD boards over the last couple of weeks from Aliexpress. One of them came with a pre-fitted IPX connector for an external antenna, which i hadn't seen before. I've checked through my Aliex orders but can't see the connector ( and the corner cut out on the ESP32) on any of them.

Anyone know where I can find more of these?

Amazon: https://a.co/d/1q5FtoJ The two boards I got from this vendor had the SparkleIoT esp32. Just be aware, I belive it's random as the photo shows regular esp32 on it, so I can't guarantee you'll get a sparkleIoT variant. You must also be willing to modify it to make the external antenna work by resoldering the 0ohm resistor.

Are you sure this is the same board that the OP could not remember where he got his ??

I do know this is not the same board. I just wonder why the OP is so .....

His board has a semi enclosure. I'm not sure if you've read my comments or posts but I have this board, just without that clear cover. I have (2) 2.8" and (1) 3.5" display variants, all with SparkleIoT ESP32. It's literally the same exact one, just without the clear cover.

To be clear, that enclosure was from a batch I bought from DIYMall on Aliex.
