How to use RX pin for USART to receive data

I am using a Nucleo-L476RG board and I am using USART2 for serial communication. I bought the sparkfun QR scanner module and it has a TX and RX pin. Can I simply connect the TX pin from the scanner to the RX pin (PA3) of USART2 and receive the data from the QR scanner?

These look to generate CMOS levels, so TX to STM32 UART-RX, appropriate baud rate / format
