Perhaps without many of us realising it, our single board computers perform the task of making programming their processor or SoC a lot easier. They take care of setting the right lines or commands to ...

I'm a big fan of the ESP32, and I have a few different boards that I play around with. I have two of the "classic" ESP32 microcontrollers, an ESP32-C6 with Zigbee and Thread support, and an ESP32-S3.

Recent reports have circulated concerning ESP32 chips, initially suggesting the presence of a “backdoor.” This claim originated from a press release by the Tarlogic research team, which has since been ...

The CL-32 is a work-in-progress pocket-sized PC that combines modern hardware with classic design inspired by systems from the 1980s like the TRS-80 Pocket Computer. While some details haven’t been ...

Update 3/9/25: After receiving concerns about the use of the term 'backdoor' to refer to these undocumented commands, we have updated our title and story. Our original story can be found here. The ...

A hot potato: The ESP32 chip, found in over a billion devices worldwide, contains undocumented vendor-specific commands that could potentially be misused to access device memory and manipulate ...

Researchers have uncovered a proprietary undocumented command in Chinese manufacturer Espressif's ESP32 chips that could be exploited, to the potential detriment of millions of users. The ESP32 chip ...

When working on a project, plenty of us will reach for an Atmel microcontroller because of the widespread prevalence of the Arduino platform. A few hackers would opt for a bit more modern part like an ...
