Arduino Serial1 reliability across different boards?

john cary 120

Quick question for developers working with Arduino boards 👇

Has anyone compared UART/Serial reliability between the Uno Q, Teensy 4.1, and Giga R1 for continuous high-speed sensor data streams?

I’m especially curious about real-world experience with:

packet integrity at 115200 baud,

buffer handling,

and long continuous Serial1 communication without dropped bytes.

Would love to hear what boards people trust most for stable sensor/LiDAR communication projects.
