This project can be tested in two primary configurations: a basic UART loopback for initial validation and a full RS-485 setup using TTL to RS-485 converters. The following sections detail the wiring ...

Ever wondered how hackers “talk” to a device when there's no screen, no keyboard, and no software interface? Welcome to the world of UART — a hardware communication protocol quietly hiding in plain ...

🛠️ No debugger? No problem. UART is your best friend. Before JTAG, before SWD, before fancy IDEs — engineers shipped real firmware with nothing but a serial terminal and printf. UART debugging is ...

The ESP32 Bus Pirate project has received a major update, further transforming it into a powerful and affordable embedded systems debugging platform. Originally inspired by the Classic Bus Pirate, ...

USB-Cereal is a powerful, fully open-source development tool that simplifies the testing, development, debugging, and manufacturing of devices that utilize USB-C. This USB-Cereal fork by 0xDA makes ...

We’ve seen some interesting USB hardware hacking/debugging boards in the last two months with Tigard, Ollie, and Glasgow Interface Explorer each with their own price point and features, but with the ...

The microcontroller (MCU) is a brilliant invention, but it can be truly frustrating when it doesn’t function as expected. Most issues can be traced back to one of two things: a failure to understand a ...
