WebMar 15, 2024 · Hello! I'm currently trying to communicate my ESP32 DevKitV1 through serial. I bought a TTL-RS232 like this one: // Note the format for setting a serial port is as follows: Serial2.begin (baud-rate, protocol, RX pin, TX pin); I'm using HardwareSerial since I've seen everyone saying it's better that SoftwareSerial, and what I want to do is to ... http://praktische-elektronik.dr-k.de/Praktikum/Digital/Le-LogikPegel.html

If there's no pull-up to 5V you're in luck: your 0-3.3V signal will just plug and play, without translation. If however the input is 5V 'CMOS', it will have an input-high level of about 2/3 Vcc, or 3.3V.
