Simultaneous RFID Reader Missing Font Like Error

Sensors NFC & RFID

Hi, I have a Simultaneous RFID Reader on a Arduino board. I used the Example1_Constant_Read and I was able to upload into the board. But when I check the Serial Monitor, I am getting ??? text like its missing a font. Any ideas? I am new to this.

Attached image is the serial monitor error

That usually means the “baud rate” selected doesn’t match; I believe that board uses 115200…also make sure the UART switch is on “SW” https://learn.sparkfun.com/tutorials/si … stant-read

The “baud rate” was the fix. Thanks!
