ESP32-WROOM-32U

Postby rahmaevao » Thu Nov 01, 2018 12:38 pm

My sketch for ESP32-WROOM works flawlessly.
But when I load it into ESP32-WROOM-32U I have problems:
for example I2C does not start at 80 MHz, but WIFI does not start at 40 MHz.

What is the difference between the two types of controllers :?:
How to migrate from just WROOM to WROOM-32D / U :?:

I use ESP32 arduino.
