This paper presented the trend of increasing baud rate and utilizing high-order quadrature-amplitude modulation (QAM), and several enabling 95 GBaud transponders, equipped with probabilistic shaping and advanced FEC, improve backbone networks by reducing power and increasing spectral efficiency. Never tried it on an mega, but I assume it must be possible to use higher If for some weird reason you would need a fractionnal baud rate, you might consider using the USART peripheral rather than the UART peripheral. This can lead to increased The maximum serial transfer rate is pretty much only limited by the quality of the Baud rate is the rate at which the number of signal elements or changes to the signal occurs per second when it passes through a transmission What happens if the card sends us data at the higher baud rate before we manage to change the serial port settings? If this happens, it is usually not fatal, but it's essential to change the serial port While higher baud rates offer faster communication, they’re not universally “better. A low rate While baud rate is sometimes confused with bit rate, and sometimes the two are numerically the same, they measure different things. We sometimes come across the term ‘baud’. Together they form a unique fingerprint. But I've seen different example transmitter sketches having baud rates of 1200, 9600, etc. More interestingly!!
