U0TXD Resistor

[cowlum]

Hi

Im designing my own PCB and have a question about the resistor on page 9 section 2.8 UART of the esp32_hardware_design_guidelines_en.pdf.

If I'm using the esp-wroom32e module am I required to place this resistor on the board?

I cannot see the resistor in the schmatic on page 19 of the esp32-wroom-32_datasheet_en.pdf

Further information that may or may not help. I will be transmitting to a max2323 in order for that chip to make the signal RS232.

Thanks

The schematic for that module is in figure 4, page 22, of the datasheet. That indicates that the resistor already is embedded in the module, so you don't need to add it externally.

Thank you very much.
