At the fundamental level, the ESP32 is the same as Arduino and RPi Pico boards: it’s a microcontroller that’s useful for any DIY project involving heavy circuitry, robotics, or automation.

An ESP32 serves as the heart of this build. It’s hooked up with a JSY-MK-194G energy metering module, which uses a current clamp and transformer in order to accurately monitor the amount of ...

Raspberry Pi HATs offer small, stackable data acquisition with features like analog and digital I/O.

When we think of threats from cybercriminals, we immediately think about Wi-Fi and the internet. Consequently, most of the ...

It’s time to start up some tutorials! The ESP32 module comes preloaded with a ROM image with an AT command set, just like the ESP8266 did. If you want to waste 95% of this chip’s potential by ...

The M5Stack Tab5 may look like a small tablet, but it's an ESP32-P4 IoT development kit with a 5-inch touchscreen display, a ...

Espressif’s popular ESP32 microchip, found in over a billion devices, has been caught with its digital trousers down, thanks to an undocumented "backdoor" lurking in its Bluetooth firmware.

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 is significant. In their ...

The researchers presented their findings at RootedCON in Madrid, revealing undocumented proprietary HCI commands in the ESP32's Bluetooth firmware. This set of 29 hidden vendor-specific commands ...

Researchers at security firm Tarlogic discovered 29 undocumented Host Controller Interface commands within the ESP32’s Bluetooth firmware. These commands enable low-level control over some ...
