I’ve been testing out the RYB2340 Bluetooth module, and it’s honestly one of the simplest ways I’ve found to add wireless control to Arduino or ESP8266 projects. In this video, I’ll walk you through ...

Espressif has unveiled its latest major chip in the form of the ESP32-E22. Officially referred to as a Radio Co-Processor (RCP), it’s intended to be used via its PCIe 2.1 or SDIO 3.0 host interface to ...

There’s a famous book that starts: “It is a truth universally acknowledged that a man in possession of a good e-ink display, must be in want of a weather station.” — or something like that, anyway. We ...

One of the main reasons Nano Banana has become so popular is its ability to generate image variations while maintaining consistency in elements that you wish to keep unchanged. For example, I asked it ...

Abstract: This study experimentally examined the energy usage of the ESP32 and Arduino Nano microcontroller boards in active and deep sleep (power-down) modes. Both boards were powered by a continuous ...

Arduino has shrunk the UNO R4 with the Arduino Nano R4 board equipped with the same 48 MHz Renesas RA4M1 32-bit Arm Cortex-M4F microcontroller, but offered in a much more compact form factor. It’s ...

Mobile network anomalies consistent with cell phone surveillance were detected at a July 4 protest at an Immigration and Customs Enforcement field office in Washington state. Those anomalies, ...

GUITION JC1060P470C is an ESP32-P4 board with an integrated 7-inch touchscreen display and an ESP32-C6 WiFi 6 and Bluetooth 5 module providing wireless connectivity. The display also features a ...

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. The ...

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 ...
