MOD-RFID1356MIFARE + UART + ESP32-EVB

[GeorgeFlorian]

Hello.

I am looking to integrate the RF-ID reader to an ongoing project on ESP32-EVB and I am curios as to what pins from the UART does the RFID1356MIFARE use.

Currently I am using the following pins from the UART:

• Pin 5 - GPIO 16
• Pin 6 - GPIO 13
• Pin 7 - GPIO 15
• Pin 9 - GPIO 14
• Pin 10 - GPIO 17

Which is almost all of them, except for Pin 3(GPIO4), Pin 4(GPIO36) and Pin 8(GPIO2).

I want to use the RFID1356MIFARE exclusively in UART Mode to receive the information via Serial. The documentation states that it uses Pin 2(GND), Pin 3(GPIO4) and Pin 4(GPIO36).

Firstly, I would like to know if I can read cards using the RFID1356MIFARE in UART Mode.

Secondly, I want to know if there will be any problem for the RFID1356MIFARE if I send or receive signals on the other UART pins. Will that interfere in some way ?

Thank you.

Seems ok.

It would be mostly a software effort but as long as you establish UART between the ESP32 and RFID1356MIFARE - everything should work. Remember the UART requires 38400 baud.

Ok.

Thank you.
