M5Stack ESP32-S3-Pico-based devkits: ATOMS3R with 0.85-inch color display, and ATOMS3R Cam with VGA camera

M5Stack ATOMS3R and ATOMS3R Cam are two tiny devkits based on ESP32-S3-Pico system-in-package and a similar design but the first one features a 0.85-inch color color IPS display, while the other is equipped with a GC0308 VGA camera. Both modules measure just 24x24mm with a thickness of around 13mm, integrate BMM150 and BMI270 motion sensors, offer GPIO expansion through female headers and a grove connector, and feature an infrared transmitter and a USB Type-C port for power and programming. Those are the second devkits based on the ESP32-S3-Pico SiP after we covered the tiny OMGS3 module earlier this week. M5Stack ATOMS3R with display ATOMS3R specifications: SiP – Espressif ESP32-S3-PICO-1-N8R8 SoC ESP32-S3 dual-core Tensilica LX7 up to 240 MHz with 512KB SRAM, 16 KB RTC SRAM Wireless – WiFi 4 and Bluetooth 5 LE + Mesh Memory – 8MB QSPI PSRAM Storage – 8MB QSPI flash Display – 0.85-inch color IPS screen […]

nRFBOX V2 ESP32 wireless hacking tool can scan, analyze, spoof, and jam the whole 2.4GHz spectrum

CiferTech has recently introduced the nRFBOX V2 ESP32-based wireless hacking tool designed for spectrum analysis, jamming, BLE device emulation, and more. The device is built around an ESP32-WROOM-32U module and includes an NRF24 module covering the whole 2.4GHz spectrum. Additionally, the device has a 0.96-inch OLED display, a five-way microswitch control pad, and a WS2812 RGB LED for feedback. The device can also be operated with a single 3.7V lithium battery, and that batter’s charging is handled by a TP4056 charging IC. All these features make this device useful for wireless security testing, educational environments, research, and hobbyist projects. Previously we have written about similar portable hacking tools like the DSTIKE Deauther Watch X, the HackBat pen-testing device, and the popular Flipper Zero wireless hacking tool. Feel free to check those out if you are looking for similar products. nRFBOX V2 specifications Microcontroller – ESP32-WROOM-32U with ESP32 dual-core wireless microcontroller […]

Bluetooth 6.0 features accurate two-way ranging using Channel Sounding, latency reduction, improved scanning efficiency, and more

The Bluetooth Special Interest Group (SIG) has just announced the release of the Bluetooth 6.0 Core Specification with features and feature enhancements that include Bluetooth Channel Sounding for two-way ranging between BLE devices, decision-based advertising filtering and monitoring advertisers to improve device scanning efficiency, an enhancement to the Isochronous Adaptation Layer (ISOAL) for lower latency and higher reliability, the LL extended feature set, and a frame space update for throughput optimization. Bluetooth 5.4 was released as a minor update mostly adding electronic shelf label (ESL) support in February 2023, or about 18 months ago, but Bluetooth 6.0 is a major update with the most notable feature being Bluetooth Channel Sounding to enable two-way ranging between two Bluetooth LE devices. It’s not the first time we’ve heard about “Bluetooth Channel Sounding” for distance measurements as it was implemented in WiFi 7/6 and Bluetooth 5.4 chipsets such as Synaptics SYN4382 and Broadcom […]
