The project started as a challenge for [Paul] to build the smallest ESP32 that would still function. That means carving away nearly everything normally found accompanying one of these chips.

It’s a straightforward enough CH340C design that also has a USBC-PD chip on-board allowing powering of an attached ESP32 from PD sources.

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 ...

According to researchers, the ESP32 is "a microcontroller that enables WiFi and Bluetooth connection." In 2023, Espressif reported that one billion units of its ESP32 chip had been sold globally.

The researchers warned that ESP32 is one of the world's most widely used chips for Wi-Fi + Bluetooth connectivity in IoT (Internet of Things) devices, so the risk of any backdoor in them is ...

Researchers have found undocumented commands in a popular bluetooth chip which is inside over a billion devices worldwide. The secret commands are in the ESP32 chip, which is made by Espressif ...

"While these debug commands exist, they cannot, by themselves, pose a security risk to ESP32 chips. Espressif will still provide a software fix to remove these undocumented commands," says Espressif.

According to researchers, the ESP32 is "a microcontroller that enables WiFi and Bluetooth connection." In 2023, Espressif reported that one billion units of its ESP32 chip had been sold globally.
