Re: Guidelines for external antenna layout

We have some ESP32 Wrover B here but meant to get the Wover IB. I assume the only difference is that the model B is missing the Ipex connector and the O ohm jumper resistor needs to be moved from r15 to r14 correct?

Best:) :) :)

differnces between ESP32-WROOM-32U (16MB) and ESP32-WROVER-IB (16mb)?

Apart from the speed difference of ram (133 vs 144 mhz) what are the differnces between the 2 models?

Id choose the smaller size of the wroom over the wrover but not at the cost of loosing some memory. The documentation doesn't really make it totally clear so any insight is very welcome
