Deep dives into hardware security, embedded systems, and cybersecurity research
UART (Universal Asynchronous Receiver/Transmitter) is a hardware communication protocol used for asynchronous serial communication between devices. It's one of the simplest ways to send data between microcontrollers, computers, and peripherals.
READ MORE →UART stands for Universal Asynchronous Receiver/Transmitter. It's basically a hardware communication protocol that acts like a translator between your computer and other serial devices, sending data one bit at a time over just a couple of wires.
