Olá pessoal! Estou tentando comunicar, sem sucesso, um ESP32 S3 N16R8 com um módulo RFID RC522. Estou usando esta programação (ela é o auto teste que vem junto com a library)
// ESP32-S3-DevKitC-1 - ESP32_S3 to MFRC522 CheckFirmware test
/*
* --------------------------------------------------------------------------------------------------------------------
* Example to test your firmware.
* --------------------------------------------------------------------------------------------------------------------
* This is a MFRC522 library example; for further details and other examples see: https://github.com/OSSLibraries/Arduino_MFRC522v2
*
* This example test the firmware of your MFRC522 reader module, only known version can be checked. If the test passed
* it do not mean that your module is faultless! Some modules have bad or broken antennas or the PICC is broken.

Porém está dando erro e o serial está retornando o seguinte:

Até agora já tentei:
- Refiz a montagem com fios de protoboard e fios menores
- Testei com outro módulo RC522
- Testei continuidade entre cada pino, revisando conexão e se a pinagem estava certa
