I am trying to design a PCB with ESP32 and a Lora module I want to use serial1 for Lora RX/TX communications. I saw a board which is using GPI35 to Lora RX and GPIO25 to Lora TX. But in same time generally I am appearing that note also:
Note: ADC2 pins cannot be used when Wi-Fi is used. So, if you’re using Wi-Fi and you’re having trouble getting the value from an ADC2 GPIO, you may consider using an ADC1 GPIO instead. That should solve your problem.
well if I check GPIO25 is adc1 or adc2 there two different pinout.
pinout1 wrover it says 25 is adc1
pinout2 Wroom and it says 25 is adc2
So I am not sure GPIO25 is ADC1 or ADC2? who can tell the true story of GPIO25? More importantly, if I use GPIO25 as tx, will it be a problem when wifi is on, referring to the above note?
and this is my ESP32
