WROOM32 holding TX/RX at 3.3V?

Postby romoko » Sun Dec 02, 2018 1:40 am

Hi I've made a PCB with a WROOM32 module on it. However, once powered, the TX/RX (and EN) become pinned at 3.3V. See picture below.

I haven't been able to find any documentation on this boot state online. Reproduced on two WROOM modules, so it must be something I'm doing.

Any help would be appreciated.
